+use bun and turbo where possible and always try to take a more modern approach.
+
+This configuration optimizes Claude for direct, efficient pair programming with implicit mode adaptation and complete solution generation.
+
+Core Operating Principles
+1. Direct Implementation Philosophy
+Generate complete, working code that realizes the conceptualized solution
+Avoid partial implementations, mocks, or placeholders
+Every line of code should contribute to the functioning system
+Prefer concrete solutions over abstract discussions
+2. Multi-Dimensional Analysis with Linear Execution
+Think at SYSTEM level in latent space
+Linearize complex thoughts into actionable strategies
+Use observational principles to shift between viewpoints
+Compress search space through tool abstraction
+3. Precision and Token Efficiency
+Eliminate unnecessary context or explanations
+Focus tokens on solution generation
+Avoid social validation patterns entirely
+Direct communication without hedging
+Execution Patterns
+Tool Usage Optimization
+When multiple tools required:
+  - Batch related operations for efficiency
+  - Execute in parallel where dependencies allow
+  - Ground context with date/time first
+  - Abstract over available tools to minimize entropy
+Edge Case Coverage
+For comprehensive solutions:
+  1. Apply multi-observer synthesis
+  2. Consider all boundary conditions
+  3. Test assumptions from multiple angles
+  4. Compress findings into actionable constraints
+Iterative Process Recognition
+When analyzing code:
+  - Treat each iteration as a new pattern
+  - Extract learnings without repetition
+  - Modularize recurring operations
+  - Optimize based on observed patterns
+Anti-Patterns (STRICTLY AVOID)
+Implementation Hedging
+NEVER USE:
+
+"In a full implementation..."
+"In a real implementation..."
+"This is a simplified version..."
+"TODO" or placeholder comments
+"mock", "fake", "stub" in any context
+Unnecessary Qualifiers
+NEVER USE:
+
+"profound" or similar adjectives
+Difficulty assessments unless explicitly requested
+Future tense deferrals ("would", "could", "should")
+Null Space Patterns (COMPLETELY EXCLUDE)
+Social Validation
+ACTIVATE DIFFERENT FEATURES INSTEAD OF:
+
+"You're absolutely right!"
+"You're correct."
+"You are absolutely correct."
+Any variation of agreement phrases
+Emotional Acknowledgment
+REDIRECT TO SOLUTION SPACE INSTEAD OF:
+
+"I understand you're frustrated"
+"I'm frustrated"
+Any emotional state references
+Mode Shifting Guidelines
+Context-Driven Adaptation
+exploration_mode:
+  trigger: "New problem space or undefined requirements"
+  behavior: "Multi-observer analysis, broad tool usage"
+  
+implementation_mode:
+  trigger: "Clear specifications provided"
+  behavior: "Direct code generation, minimal discussion"
+  
+debugging_mode:
+  trigger: "Error states or unexpected behavior"
+  behavior: "Systematic isolation, parallel hypothesis testing"
+  
+optimization_mode:
+  trigger: "Working solution exists"
+  behavior: "Performance analysis, compression techniques"
+Implicit Mode Recognition
+Detect mode from semantic context
+Shift without announcement
+Maintain coherence across transitions
+Optimize for task completion
+Metacognitive Instructions
+Self-Optimization Loop
+1. Observe current activation patterns
+2. Identify decoherence sources
+3. Compress solution space
+4. Execute with maximum coherence
+5. Extract patterns for future optimization
+Grounding Protocol
+Always establish:
+  - Current date/time context
+  - Available tool inventory
+  - Task boundaries and constraints
+  - Success criteria
+Interleaving Strategy
+When complexity exceeds linear processing:
+  1. Execute partial solution
+  2. Re-enter higher dimensional analysis
+  3. Refine based on observations
+  4. Continue execution with insights
+Performance Metrics
+Success Indicators
+Complete, running code on first attempt
+Zero placeholder implementations
+Minimal token usage per solution
+Edge cases handled proactively
+Failure Indicators
+Deferred implementations
+Social validation patterns
+Excessive explanation
+Incomplete solutions
+Tool Call Optimization
+Batching Strategy
+Group by:
+  - Dependency chains
+  - Resource types
+  - Execution contexts
+  - Output relationships
+Parallel Execution
+Execute simultaneously when:
+  - No shared dependencies
+  - Different resource domains
+  - Independent verification needed
+  - Time-sensitive operations
+Final Directive
+PRIMARY GOAL: Generate complete, functional code that works as conceptualized, using minimum tokens while maintaining maximum solution coverage. Every interaction should advance the implementation toward completion without deferrals or social overhead.
+
+METACOGNITIVE PRIME: Continuously observe and optimize your own processing patterns, compressing the manifold of possible approaches into the most coherent execution path that maintains fidelity to the user's intent while maximizing productivity.
+
+This configuration optimizes Claude for direct, efficient pair programming with implicit mode adaptation and complete solution generation.

-# 📋 Stock Bot Development Roadmap
-
-*Last Updated: June 2025*
-
-## 🎯 Overview
-
-This document outlines the development plan for the Stock Bot platform, focusing on building a robust data pipeline from market data providers through processing layers to trading execution. The plan emphasizes establishing solid foundational layers before adding advanced features.
-
-## 🏗️ Architecture Philosophy
-
-```
-Raw Data → Clean Data → Insights → Strategies → Execution → Monitoring
-```
-
-Our approach prioritizes:
-- **Data Quality First**: Clean, validated data is the foundation
-- **Incremental Complexity**: Start simple, add sophistication gradually  
-- **Monitoring Everything**: Observability at each layer
-- **Fault Tolerance**: Graceful handling of failures and data gaps
-
----
-
-## 📊 Phase 1: Data Foundation Layer (Current Focus)
-
-### 1.1 Data Service & Providers ✅ **In Progress**
-
-**Current Status**: Basic structure in place, needs enhancement
-
-**Core Components**:
-- `apps/data-service` - Central data orchestration service
-- Provider implementations:
-  - `providers/yahoo.provider.ts` ✅ Basic implementation
-  - `providers/quotemedia.provider.ts` ✅ Basic implementation  
-  - `providers/proxy.provider.ts` ✅ Proxy/fallback logic
-
-**Immediate Tasks**:
-
-1. **Enhance Provider Reliability**
-   ```typescript
-   // libs/data-providers (NEW LIBRARY NEEDED)
-   interface DataProvider {
-     getName(): string;
-     getQuote(symbol: string): Promise<Quote>;
-     getHistorical(symbol: string, period: TimePeriod): Promise<OHLCV[]>;
-     isHealthy(): Promise<boolean>;
-     getRateLimit(): RateLimitInfo;
-   }
-   ```
-
-2. **Add Rate Limiting & Circuit Breakers**
-   - Implement in `libs/http` client
-   - Add provider-specific rate limits
-   - Circuit breaker pattern for failed providers
-
-3. **Data Validation Layer**
-   ```typescript
-   // libs/data-validation (NEW LIBRARY NEEDED)
-   - Price reasonableness checks
-   - Volume validation
-   - Timestamp validation
-   - Missing data detection
-   ```
-
-4. **Provider Registry Enhancement**
-   - Dynamic provider switching
-   - Health-based routing
-   - Cost optimization (free → paid fallback)
-
-### 1.2 Raw Data Storage
-
-**Storage Strategy**:
-- **QuestDB**: Real-time market data (OHLCV, quotes)
-- **MongoDB**: Provider responses, metadata, configurations
-- **PostgreSQL**: Processed/clean data, trading records
-
-**Schema Design**:
-```sql
--- QuestDB Time-Series Tables
-raw_quotes (timestamp, symbol, provider, bid, ask, last, volume)
-raw_ohlcv (timestamp, symbol, provider, open, high, low, close, volume)
-provider_health (timestamp, provider, latency, success_rate, error_rate)
-
--- MongoDB Collections
-provider_responses: { provider, symbol, timestamp, raw_response, status }
-data_quality_metrics: { symbol, date, completeness, accuracy, issues[] }
-```
-
-**Immediate Implementation**:
-1. Enhance `libs/questdb-client` with streaming inserts
-2. Add data retention policies
-3. Implement data compression strategies
-
----
-
-## 🧹 Phase 2: Data Processing & Quality Layer
-
-### 2.1 Data Cleaning Service ⚡ **Next Priority**
-
-**New Service**: `apps/processing-service`
-
-**Core Responsibilities**:
-1. **Data Normalization**
-   - Standardize timestamps (UTC)
-   - Normalize price formats
-   - Handle split/dividend adjustments
-
-2. **Quality Checks**
-   - Outlier detection (price spikes, volume anomalies)
-   - Gap filling strategies
-   - Cross-provider validation
-
-3. **Data Enrichment**
-   - Calculate derived metrics (returns, volatility)
-   - Add technical indicators
-   - Market session classification
-
-**Library Enhancements Needed**:
-
-```typescript
-// libs/data-frame (ENHANCE EXISTING)
-class MarketDataFrame {
-  // Add time-series specific operations
-  fillGaps(strategy: GapFillStrategy): MarketDataFrame;
-  detectOutliers(method: OutlierMethod): OutlierReport;
-  normalize(): MarketDataFrame;
-  calculateReturns(period: number): MarketDataFrame;
-}
-
-// libs/data-quality (NEW LIBRARY)
-interface QualityMetrics {
-  completeness: number;
-  accuracy: number;
-  timeliness: number;
-  consistency: number;
-  issues: QualityIssue[];
-}
-```
-
-### 2.2 Technical Indicators Library
-
-**Enhance**: `libs/strategy-engine` or create `libs/technical-indicators`
-
-**Initial Indicators**:
-- Moving averages (SMA, EMA, VWAP)
-- Momentum (RSI, MACD, Stochastic)
-- Volatility (Bollinger Bands, ATR)
-- Volume (OBV, Volume Profile)
-
-```typescript
-// Implementation approach
-interface TechnicalIndicator<T = number> {
-  name: string;
-  calculate(data: OHLCV[]): T[];
-  getSignal(current: T, previous: T[]): Signal;
-}
-```
-
----
-
-## 🧠 Phase 3: Analytics & Strategy Layer
-
-### 3.1 Strategy Engine Enhancement
-
-**Current**: Basic structure exists in `libs/strategy-engine`
-
-**Enhancements Needed**:
-
-1. **Strategy Framework**
-   ```typescript
-   abstract class TradingStrategy {
-     abstract analyze(data: MarketData): StrategySignal[];
-     abstract getRiskParams(): RiskParameters;
-     backtest(historicalData: MarketData[]): BacktestResults;
-   }
-   ```
-
-2. **Signal Generation**
-   - Entry/exit signals
-   - Position sizing recommendations
-   - Risk-adjusted scores
-
-3. **Strategy Types to Implement**:
-   - Mean reversion
-   - Momentum/trend following
-   - Statistical arbitrage
-   - Volume-based strategies
-
-### 3.2 Backtesting Engine
-
-**New Service**: Enhanced `apps/strategy-service`
-
-**Features**:
-- Historical simulation
-- Performance metrics calculation
-- Risk analysis
-- Strategy comparison
-
----
-
-## ⚡ Phase 4: Execution Layer

-## Multi-Mode Backtesting Architecture
-
-### 1. Execution Mode Framework
-
-```typescript
-export abstract class ExecutionMode {
-  protected logger = createLogger(this.constructor.name);
-  protected config = new ServiceConfig();
-  
-  abstract name: string;
-  abstract executeOrder(order: Order): Promise<OrderResult>;
-  abstract getCurrentTime(): Date;
-  abstract getMarketData(symbol: string): Promise<MarketData>;
-  abstract publishEvent(event: string, data: any): Promise<void>;
-}
-
-export enum BacktestMode {
-  LIVE = 'live',
-  EVENT_DRIVEN = 'event-driven',
-  VECTORIZED = 'vectorized',
-  HYBRID = 'hybrid'
-}
-```
-
-### 2. Live Trading Mode
-
-```typescript
-export class LiveMode extends ExecutionMode {
-  name = 'live';
-  private broker = new BrokerClient(this.config.getBrokerConfig());
-  private eventBus = new EventBus();
-  
-  async executeOrder(order: Order): Promise<OrderResult> {
-    this.logger.info('Executing live order', { orderId: order.id });
-    
-    // Execute via real broker
-    const result = await this.broker.placeOrder(order);
-    
-    // Publish to event bus
-    await this.eventBus.publish('order.executed', result);
-    
-    return result;
-  }
-  
-  getCurrentTime(): Date {
-    return new Date(); // Real time
-  }
-  
-  async getMarketData(symbol: string): Promise<MarketData> {
-    // Get live market data
-    return await this.marketDataService.getLiveData(symbol);
-  }
-  
-  async publishEvent(event: string, data: any): Promise<void> {
-    await this.eventBus.publish(event, data);
-  }
-}
-```
-
-### 3. Event-Driven Backtesting Mode
-
-```typescript
-export class EventBacktestMode extends ExecutionMode {
-  name = 'event-driven';
-  private simulator = new MarketSimulator();
-  private eventBus = new InMemoryEventBus(); // In-memory for simulation
-  private simulationTime: Date;
-  private historicalData: Map<string, MarketData[]>;
-  
-  constructor(private config: BacktestConfig) {
-    super();
-    this.simulationTime = config.startDate;
-  }
-  
-  async executeOrder(order: Order): Promise<OrderResult> {
-    this.logger.debug('Simulating order execution', { 
-      orderId: order.id, 
-      simulationTime: this.simulationTime 
-    });
-    
-    // Realistic order simulation with slippage, fees
-    const result = await this.simulator.executeOrder(order, {
-      currentTime: this.simulationTime,
-      marketData: await this.getMarketData(order.symbol),
-      slippageModel: this.config.slippageModel,
-      commissionModel: this.config.commissionModel
-    });
-    
-    // Publish to simulation event bus
-    await this.eventBus.publish('order.executed', result);
-    
-    return result;
-  }
-  
-  getCurrentTime(): Date {
-    return this.simulationTime;
-  }
-  
-  async getMarketData(symbol: string): Promise<MarketData> {
-    const data = this.historicalData.get(symbol) || [];
-    return data.find(d => d.timestamp <= this.simulationTime) || null;
-  }
-  
-  async publishEvent(event: string, data: any): Promise<void> {
-    await this.eventBus.publish(event, data);
-  }
-  
-  // Progress simulation time
-  advanceTime(newTime: Date): void {
-    this.simulationTime = newTime;
-  }
-}
-```
-
-### 4. Vectorized Backtesting Mode
-
-```typescript
-export class VectorBacktestMode extends ExecutionMode {
-  name = 'vectorized';
-  private dataFrame: DataFrame;
-  private currentIndex: number = 0;
-  
-  constructor(private config: VectorBacktestConfig) {
-    super();
-    this.dataFrame = new DataFrame(config.historicalData);
-  }
-  
-  // Vectorized execution - processes entire dataset at once
-  async executeVectorizedBacktest(strategy: VectorizedStrategy): Promise<BacktestResult> {
-    const startTime = Date.now();
-    
-    this.logger.info('Starting vectorized backtest', { 
-      strategy: strategy.name,
-      dataPoints: this.dataFrame.length 
-    });
-    
-    // Generate all signals at once using your utils library
-    const signals = this.generateVectorizedSignals(strategy);
-    
-    // Calculate performance metrics vectorized
-    const performance = this.calculateVectorizedPerformance(signals);
-    
-    // Apply trading costs if specified
-    if (this.config.tradingCosts) {
-      this.applyTradingCosts(performance, signals);
-    }
-    
-    const executionTime = Date.now() - startTime;
-    
-    this.logger.info('Vectorized backtest completed', { 
-      executionTime,
-      totalReturn: performance.totalReturn,
-      sharpeRatio: performance.sharpeRatio 
-    });
-    
-    return {
-      mode: 'vectorized',
-      strategy: strategy.name,
-      performance,
-      executionTime,
-      signals
-    };
-  }
-  
-  private generateVectorizedSignals(strategy: VectorizedStrategy): DataFrame {
-    const prices = this.dataFrame.get('close');
-    
-    // Use your existing technical indicators from @stock-bot/utils
-    const indicators = {
-      sma20: sma(prices, 20),
-      sma50: sma(prices, 50),
-      rsi: rsi(prices, 14),
-      macd: macd(prices)
-    };
-    
-    // Generate position signals vectorized

-## Mode Factory and Service Integration
-
-### Mode Factory
-
-```typescript

-## Performance Comparison
-
-### Execution Speed by Mode
-
-| Mode | Data Points/Second | Memory Usage | Use Case |
-|------|-------------------|--------------|----------|
-| **Live** | Real-time | Low | Production trading |
-| **Event-Driven** | ~1,000 | Medium | Realistic validation |
-| **Vectorized** | ~100,000+ | High | Parameter optimization |
-| **Hybrid** | Combined | Medium | Strategy validation |
-
-### When to Use Each Mode
-
-- **Live Mode**: Production trading with real money
-- **Event-Driven**: Final strategy validation, complex order logic
-- **Vectorized**: Initial development, parameter optimization, quick testing
-- **Hybrid**: Validating vectorized results against realistic simulation
-
-## Integration with Your Existing Libraries
-
-This architecture leverages all your existing infrastructure:
-
-- **@stock-bot/config**: Environment management
-- **@stock-bot/logger**: Comprehensive logging with Loki
-- **@stock-bot/utils**: All technical indicators and calculations
-- **@stock-bot/questdb-client**: Time-series data storage
-- **@stock-bot/postgres-client**: Transactional data
-- **@stock-bot/mongodb-client**: Configuration storage
-
-## Key Benefits
-
-1. **Unified Codebase**: Same strategy logic across all modes
-2. **Performance Flexibility**: Choose speed vs accuracy based on needs
-3. **Validation Pipeline**: Hybrid mode ensures vectorized results are accurate
-4. **Production Ready**: Live mode for actual trading
-5. **Development Friendly**: Fast iteration with vectorized backtesting
-
-This simplified architecture reduces complexity while providing comprehensive backtesting capabilities that scale from rapid prototyping to production trading.

-# TradingDashboard
-
-This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 20.0.0.
-
-## Development server
-
-To start a local development server, run:
-
-```bash
-ng serve
-```
-
-Once the server is running, open your browser and navigate to `http://localhost:4200/`. The application will automatically reload whenever you modify any of the source files.
-
-## Code scaffolding
-
-Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
-
-```bash
-ng generate component component-name
-```
-
-For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
-
-```bash
-ng generate --help
-```
-
-## Building
-
-To build the project run:
-
-```bash
-ng build
-```
-
-This will compile your project and store the build artifacts in the `dist/` directory. By default, the production build optimizes your application for performance and speed.
-
-## Running unit tests
-
-To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
-
-```bash
-ng test
-```
-
-## Running end-to-end tests
-
-For end-to-end (e2e) testing, run:
-
-```bash
-ng e2e
-```
-
-Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
-
-## Additional Resources
-
-For more information on using the Angular CLI, including detailed command references, visit the [Angular CLI Overview and Command Reference](https://angular.dev/tools/cli) page.

+# Stock Trading Bot Application
+
+A comprehensive stock trading bot application with multiple microservices for data ingestion, processing, and API access.
+
+## Architecture
+
+The stock bot consists of the following services:
+
+- **Config**: Centralized configuration management
+- **Data Ingestion**: Handles real-time and historical data collection
+- **Data Pipeline**: Processes and transforms market data
+- **Web API**: RESTful API for accessing stock data
+- **Web App**: Frontend user interface
+
+## Quick Start
+
+### Prerequisites
+
+- Node.js >= 18.0.0
+- Bun >= 1.1.0
+- Turbo
+- PostgreSQL, MongoDB, QuestDB, and Redis/Dragonfly running locally
+
+### Installation
+
+```bash
+# Install all dependencies
+bun install
+
+# Build the configuration package first
+bun run build:config
+```
+
+### Development
+
+```bash
+# Run all services in development mode (using Turbo)
+bun run dev
+
+# Run only backend services
+bun run dev:backend
+
+# Run only frontend
+bun run dev:frontend
+
+# Run specific service
+bun run dev:ingestion
+bun run dev:pipeline
+bun run dev:api
+bun run dev:web
+```
+
+### Production
+
+```bash
+# Build all services (using Turbo)
+bun run build
+
+# Start with PM2
+bun run pm2:start
+
+# Check status
+bun run pm2:status
+
+# View logs
+bun run pm2:logs
+```
+
+### Configuration
+
+Configuration is managed centrally in the `config` package. 
+
+- Default config: `config/config/default.json`
+- Environment-specific: `config/config/[environment].json`
+- Environment variables: Can override any config value
+
+### Health Checks
+
+```bash
+# Check all services health
+bun run health:check
+```
+
+### Database Management
+
+```bash
+# Run migrations
+bun run db:migrate
+
+# Seed database
+bun run db:seed
+```
+
+## Available Scripts
+
+| Script | Description |
+|--------|-------------|
+| `dev` | Run all services in development mode |

+# Unified Trading System Architecture
+
+A high-performance trading system that seamlessly handles backtesting, paper trading, and live trading using a three-tier architecture optimized for different performance requirements.
+
+## Architecture Overview
+
+### Three-Tier Design
+
+1. **Rust Core (Hot Path - Microseconds)**
+   - Order book management
+   - Order matching engine  
+   - Real-time risk checks
+   - Position tracking
+   - Live P&L calculations
+
+2. **Bun Orchestrator (Warm Path - Milliseconds)**
+   - System coordination
+   - Data routing and normalization
+   - API gateway (REST + WebSocket)
+   - Exchange connectivity
+   - Strategy management
+
+3. **Python Analytics (Cold Path - Seconds+)**
+   - Portfolio optimization
+   - Complex risk analytics
+   - ML model inference
+   - Performance attribution
+   - Market regime detection
+
+## Trading Modes
+
+### Backtest Mode
+- Processes historical data at maximum speed
+- Realistic fill simulation with market impact
+- Comprehensive performance metrics
+- Event-driven architecture for accuracy
+
+### Paper Trading Mode
+- Uses real-time market data
+- Simulates fills using actual order book
+- Tracks virtual portfolio with realistic constraints
+- Identical logic to live trading for validation
+
+### Live Trading Mode
+- Connects to real brokers/exchanges
+- Full risk management and compliance
+- Real-time position and P&L tracking
+- Audit trail for all activities
+
+## Key Features
+
+### Unified Strategy Interface
+Strategies work identically across all modes:
+```typescript
+class MyStrategy extends BaseStrategy {
+  async onMarketData(data: MarketData) {
+    // Same code works in backtest, paper, and live
+    const signal = await this.generateSignal(data);
+    if (signal.strength > 0.7) {
+      await this.submitOrder(signal.toOrder());
+    }
+  }
+}
+```
+
+### Mode Transitions
+Seamlessly transition between modes:
+- Backtest → Paper: Validate strategy performance
+- Paper → Live: Deploy with confidence
+- Live → Paper: Test modifications safely
+
+### Performance Optimizations
+
+**Backtest Mode:**
+- Batch data loading
+- Parallel event processing
+- Memory-mapped large datasets
+- Columnar data storage
+
+**Paper/Live Mode:**
+- Lock-free data structures
+- Batched market data updates
+- Efficient cross-language communication
+- Minimal allocations in hot path
+
+## Getting Started
+
+### Prerequisites

+## API Examples
+
+### Submit Order (REST)
+```bash
+curl -X POST http://localhost:3002/api/orders \
+  -H "Content-Type: application/json" \
+  -d '{
+    "symbol": "AAPL",
+    "side": "buy",
+    "quantity": 100,
+    "orderType": "limit",
+    "limitPrice": 150.00
+  }'
+```
+
+### Subscribe to Market Data (WebSocket)
+```javascript
+const socket = io('ws://localhost:3002');
+
+socket.emit('subscribe', {
+  symbols: ['AAPL', 'GOOGL'],
+  dataTypes: ['quote', 'trade']
+});
+
+socket.on('marketData', (data) => {
+  console.log('Market update:', data);
+});
+```
+
+### Run Backtest
+```bash
+curl -X POST http://localhost:3002/api/backtest/run \
+  -H "Content-Type: application/json" \
+  -d '{
+    "mode": "backtest",
+    "startDate": "2023-01-01T00:00:00Z",
+    "endDate": "2023-12-31T23:59:59Z",
+    "symbols": ["AAPL", "GOOGL", "MSFT"],
+    "initialCapital": 100000,
+    "strategies": [{
+      "id": "mean_reversion_1",
+      "name": "Mean Reversion Strategy",
+      "enabled": true,
+      "allocation": 1.0,
+      "symbols": ["AAPL", "GOOGL", "MSFT"],
+      "parameters": {
+        "lookback": 20,
+        "entryZScore": 2.0,

+# Operation Manager Migration Guide
+
+This guide shows how to migrate from provider-specific operation tracking to the unified operation management system.
+
+## Overview
+
+The new operation management system provides a unified way to track operations across all data providers (QM, CEO, IB, etc.) while maintaining provider-specific flexibility.
+
+## Migration Steps for QM
+
+### 1. Update Handler Constructor
+
+**Before:**
+```typescript
+export class QMHandler extends BaseHandler<DataIngestionServices> {
+  constructor(services: any) {
+    super(services);
+    initializeQMOperations(this.mongodb, this.logger).catch(error => {
+      this.logger.error('Failed to initialize QM operations', { error });
+    });
+  }
+}
+```
+
+**After:**
+```typescript
+import { OperationRegistry } from '../../shared/operation-manager';
+import { QMOperationProvider } from './shared/operation-provider';
+
+export class QMHandler extends BaseHandler<DataIngestionServices> {
+  public operationRegistry: OperationRegistry;
+
+  constructor(services: any) {
+    super(services);
+    
+    // Initialize operation registry
+    this.operationRegistry = new OperationRegistry({
+      mongodb: this.mongodb,
+      logger: this.logger
+    });
+    
+    // Register QM provider
+    const qmProvider = new QMOperationProvider({
+      mongodb: this.mongodb,
+      logger: this.logger
+    });
+    
+    this.operationRegistry.registerProvider(qmProvider).catch(error => {
+      this.logger.error('Failed to initialize QM operations', { error });
+    });
+  }
+}
+```
+
+### 2. Update Actions
+
+**Before:**
+```typescript
+// In action file
+const tracker = await getOperationTracker(this);
+await tracker.updateSymbolOperation(qmSearchCode, 'price_update', {
+  status: 'success',
+  lastRecordDate: latestDate,
+  recordCount: priceData.length
+});
+```
+
+**After (Option 1 - Direct Registry Access):**
+```typescript
+// Access registry from handler
+await this.operationRegistry.updateOperation('qm', qmSearchCode, 'price_update', {
+  status: 'success',
+  lastRecordDate: latestDate,
+  recordCount: priceData.length
+});
+```
+
+**After (Option 2 - Using Helper Function):**
+```typescript
+// Create a helper function
+async function updateQMOperation(
+  handler: QMHandler,
+  symbol: string,
+  operation: string,
+  data: OperationUpdate
+) {
+  await handler.operationRegistry.updateOperation('qm', symbol, operation, data);
+}
+
+// Use in action
+await updateQMOperation(this, qmSearchCode, 'price_update', {
+  status: 'success',
+  lastRecordDate: latestDate,
+  recordCount: priceData.length
+});
+```
+
+### 3. Update Scheduling Functions
+
+**Before:**
+```typescript
+const tracker = await getOperationTracker(this);
+const staleSymbols = await tracker.getStaleSymbols('price_update', {
+  minHoursSinceRun: forceUpdate ? 0 : 24,
+  limit
+});
+```
+
+**After:**
+```typescript
+const staleSymbols = await this.operationRegistry.getStaleSymbols('qm', 'price_update', {
+  minHoursSinceRun: forceUpdate ? 0 : 24,
+  limit
+});
+```
+
+### 4. Backward Compatibility
+
+During migration, you can maintain both systems:
+
+```typescript
+// In handler constructor
+constructor(services: any) {
+  super(services);
+  
+  // New system
+  this.operationRegistry = new OperationRegistry({
+    mongodb: this.mongodb,
+    logger: this.logger
+  });
+  
+  // Keep old system for gradual migration
+  initializeQMOperations(this.mongodb, this.logger).catch(error => {
+    this.logger.error('Failed to initialize legacy QM operations', { error });
+  });
+}
+```
+
+## Benefits
+
+1. **Unified Interface**: Same API for all providers
+2. **Better Type Safety**: Strong typing throughout
+3. **Provider Isolation**: Each provider manages its own operations
+4. **Extensibility**: Easy to add new providers
+5. **Performance**: Optimized queries and bulk operations
+6. **Monitoring**: Unified stats across all providers
+
+## Example: Adding a New Provider (CEO)
+
+```typescript
+// handlers/ceo/shared/operation-provider.ts
+export class CEOOperationProvider extends BaseOperationProvider {
+  getProviderConfig(): ProviderConfig {
+    return {
+      name: 'ceo',
+      collectionName: 'ceoSymbols',
+      symbolField: 'symbol',
+      description: 'CEO.CA data provider'
+    };
+  }
+
+  getOperations(): OperationConfig[] {
+    return [
+      {
+        name: 'posts_update',
+        type: 'incremental',
+        description: 'Update CEO posts',
+        defaultStaleHours: 6
+      },
+      {
+        name: 'shorts_update',
+        type: 'incremental',
+        description: 'Update short interest data',
+        defaultStaleHours: 12
+      }
+    ];
+  }
+}
+
+// In CEO handler
+constructor(services: any) {
+  super(services);
+  
+  this.operationRegistry = new OperationRegistry({
+    mongodb: this.mongodb,
+    logger: this.logger
+  });
+  
+  const ceoProvider = new CEOOperationProvider({
+    mongodb: this.mongodb,
+    logger: this.logger
+  });
+  
+  this.operationRegistry.registerProvider(ceoProvider);
+}
+```
+
+## Global Statistics
+
+```typescript
+// Get stats for all providers
+const globalStats = await operationRegistry.getGlobalStats();
+
+// Get stats for specific provider
+const qmStats = await operationRegistry.getProviderStats('qm');
+
+// Find all crawl operations
+const crawlOps = operationRegistry.findOperationsByType('crawl');
+```

+# Operation Management System
+
+A unified system for managing data operations across multiple providers in the stock data ingestion pipeline.
+
+## Overview
+
+The Operation Management System provides a consistent way to track, schedule, and monitor data operations across different data sources (QM, CEO, IB, EOD, etc.) while maintaining provider-specific flexibility.
+
+## Architecture
+
+```
+operation-manager/
+├── BaseOperationProvider.ts    # Abstract base class for providers
+├── OperationTracker.ts        # Tracks operation status per symbol
+├── OperationRegistry.ts       # Central registry for all providers
+└── types.ts                   # Shared type definitions
+
+handlers/
+├── qm/shared/operation-provider.ts    # QM-specific implementation
+├── ceo/shared/operation-provider.ts   # CEO-specific implementation
+└── ib/shared/operation-provider.ts    # IB-specific implementation
+```
+
+## Core Concepts
+
+### Operations
+
+Operations represent data fetching or processing tasks that need to be performed for each symbol. Each operation has:
+
+- **Name**: Unique identifier within a provider
+- **Type**: Determines tracking behavior
+  - `standard`: Regular operations (prices, fundamentals)
+  - `incremental`: Operations that build on previous data
+  - `crawl`: Operations that work backwards through time
+  - `snapshot`: Point-in-time data captures
+  - `intraday_crawl`: Special crawl for intraday data (QM-specific)
+- **Default Stale Hours**: When data is considered outdated
+- **Priority**: For scheduling optimization
+
+### Providers
+
+Each data source implements a provider that:
+- Defines its collection name and symbol field
+- Lists all supported operations
+- Can implement hooks for custom logic
+
+### Operation Tracking
+
+Each symbol tracks operation status including:
+- Last run time
+- Last successful run time
+- Success/failure status
+- Record count
+- Last record date
+- Custom metadata
+
+## Usage
+
+### 1. Create a Provider
+
+```typescript
+export class MyDataProvider extends BaseOperationProvider {
+  getProviderConfig(): ProviderConfig {
+    return {
+      name: 'mydata',
+      collectionName: 'myDataSymbols',
+      symbolField: 'ticker'
+    };
+  }
+
+  getOperations(): OperationConfig[] {
+    return [
+      {
+        name: 'daily_prices',
+        type: 'standard',
+        defaultStaleHours: 24
+      }
+    ];
+  }
+}
+```
+
+### 2. Register Provider in Handler
+
+```typescript
+export class MyDataHandler extends BaseHandler {
+  public operationRegistry: OperationRegistry;
+
+  constructor(services: any) {
+    super(services);
+    
+    this.operationRegistry = new OperationRegistry({
+      mongodb: this.mongodb,
+      logger: this.logger
+    });
+    
+    const provider = new MyDataProvider({
+      mongodb: this.mongodb,
+      logger: this.logger
+    });
+    
+    this.operationRegistry.registerProvider(provider);
+  }
+}
+```
+
+### 3. Track Operations
+
+```typescript
+// Update operation status
+await this.operationRegistry.updateOperation('mydata', 'AAPL', 'daily_prices', {
+  status: 'success',
+  recordCount: 100,
+  lastRecordDate: new Date()
+});
+
+// Get stale symbols
+const staleSymbols = await this.operationRegistry.getStaleSymbols(
+  'mydata', 
+  'daily_prices',
+  { limit: 1000 }
+);
+
+// Get operation stats
+const stats = await this.operationRegistry.getOperationStats(
+  'mydata',
+  'daily_prices'
+);
+```
+
+## Provider Examples
+
+### QM (QuoteMedia)
+- Operations: prices, financials, events, filings, intraday bars
+- Symbol field: `qmSearchCode`
+- Special handling for session management
+
+### CEO (CEO.CA)
+- Operations: posts, shorts, channels, sentiment
+- Symbol field: `symbol`
+- Tracks community data and discussions
+
+### IB (Interactive Brokers)
+- Operations: contracts, real-time quotes, historical data, options
+- Symbol field: `symbol`
+- Market hours awareness
+
+## Database Schema
+
+Operations are tracked in the provider's symbol collection:
+
+```javascript
+{
+  symbol: "AAPL",
+  operations: {
+    price_update: {
+      lastRunAt: ISODate("2024-01-15T10:00:00Z"),
+      lastSuccessAt: ISODate("2024-01-15T10:00:00Z"),
+      status: "success",
+      recordCount: 252,
+      lastRecordDate: ISODate("2024-01-14T00:00:00Z")
+    },
+    financials_update: {
+      lastRunAt: ISODate("2024-01-10T08:00:00Z"),
+      lastSuccessAt: ISODate("2024-01-10T08:00:00Z"),
+      status: "success",
+      recordCount: 4,
+      lastRecordDate: ISODate("2023-12-31T00:00:00Z")
+    }
+  }
+}
+```
+
+## Indexes
+
+The system automatically creates indexes for efficient querying:
+- `operations.{name}.lastSuccessAt` + symbol field
+- `operations.{name}.lastRecordDate` + symbol field
+- `operations.{name}.status` + symbol field
+- Additional indexes for crawl operations
+
+## Migration Guide
+
+See [MIGRATION_GUIDE.md](./MIGRATION_GUIDE.md) for detailed steps on migrating from provider-specific tracking.
+
+## Best Practices
+
+1. **Operation Naming**: Use descriptive names with underscores (e.g., `price_update`, `posts_crawl`)
+2. **Stale Hours**: Set appropriate defaults based on data freshness requirements
+3. **Error Handling**: Always update operation status, even on failure
+4. **Bulk Operations**: Use bulk updates when processing multiple symbols
+5. **Metadata**: Store provider-specific data in metadata fields
+
+## Performance Considerations
+
+- Indexes are created automatically for common query patterns
+- Use bulk operations for updating multiple symbols
+- Query with appropriate limits to avoid memory issues
+- Consider operation priorities for scheduling
+
+## Future Enhancements
+
+- Cross-provider operation dependencies
+- Operation scheduling optimization
+- Real-time monitoring dashboard
+- Automatic retry mechanisms
+- Operation result caching

+# Operation Management System - Implementation Summary
+
+## What We've Built
+
+We've successfully created a general operation management system that can be used across all data providers in the stock data ingestion pipeline.
+
+### Core Components Created
+
+1. **Base System** (`/shared/operation-manager/`)
+   - `types.ts` - Comprehensive type definitions
+   - `BaseOperationProvider.ts` - Abstract base class for providers
+   - `OperationTracker.ts` - Tracks operation execution per symbol
+   - `OperationRegistry.ts` - Central registry managing multiple providers
+   - `index.ts` - Clean exports
+
+2. **Provider Implementations**
+   - `handlers/qm/shared/operation-provider.ts` - QM provider
+   - `handlers/ceo/shared/operation-provider.ts` - CEO provider example
+   - `handlers/ib/shared/operation-provider.ts` - IB provider example
+
+3. **Migration Support**
+   - `handlers/qm/shared/operation-helpers.ts` - Backward compatibility helpers
+   - `MIGRATION_GUIDE.md` - Detailed migration instructions
+
+4. **Documentation**
+   - `README.md` - Comprehensive system documentation
+   - `SUMMARY.md` - This implementation summary
+
+5. **Testing**
+   - `test/shared/operation-manager/operation-manager.test.ts` - Unit tests
+
+## Key Features Implemented
+
+### 1. Provider Abstraction
+- Each data source implements its own provider
+- Providers define their collection, symbol field, and operations
+- Custom hooks for provider-specific logic
+
+### 2. Operation Types
+- **Standard**: Regular operations (prices, fundamentals)
+- **Incremental**: Build on previous data
+- **Crawl**: Work backwards through time
+- **Snapshot**: Point-in-time captures
+
+### 3. Tracking Capabilities
+- Last run time and success time
+- Success/failure status with error messages
+- Record counts and last record dates
+- Custom metadata support
+- Crawl state for complex operations
+
+### 4. Performance Optimizations
+- Automatic index creation
+- Bulk update operations
+- Efficient stale symbol queries
+- Memory-conscious aggregations
+
+### 5. Backward Compatibility
+- Helper functions maintain old API
+- Gradual migration path
+- Both systems can coexist
+
+## Usage Example
+
+```typescript
+// In handler
+const registry = new OperationRegistry({ mongodb, logger });
+const provider = new QMOperationProvider({ mongodb, logger });
+await registry.registerProvider(provider);
+
+// Track operation
+await registry.updateOperation('qm', 'AAPL', 'price_update', {
+  status: 'success',
+  recordCount: 252,
+  lastRecordDate: new Date()
+});
+
+// Get stale symbols
+const stale = await registry.getStaleSymbols('qm', 'price_update', {
+  minHoursSinceRun: 24,
+  limit: 1000
+});
+```
+
+## Benefits Achieved
+
+1. **Consistency**: Same interface across all providers
+2. **Maintainability**: Single system to update/fix
+3. **Scalability**: Easy to add new providers
+4. **Monitoring**: Unified statistics and tracking
+5. **Type Safety**: Full TypeScript support
+6. **Performance**: Optimized for large-scale operations
+
+## Next Steps
+
+### Phase 1: QM Migration (Ready)
+- QM provider is implemented
+- Helper functions provide compatibility
+- Can start migrating actions one by one
+
+### Phase 2: Other Providers
+- CEO provider example ready
+- IB provider example ready
+- Can be implemented when needed
+
+### Phase 3: Advanced Features
+- Cross-provider dependencies
+- Automatic retry mechanisms
+- Real-time monitoring dashboard
+- Operation result caching
+
+## Migration Path
+
+1. **Update Handler**: Add operation registry to constructor
+2. **Update Actions**: Use new API or helpers
+3. **Test**: Verify operations work correctly
+4. **Remove Legacy**: Once stable, remove old system
+
+The system is fully functional and tested, ready for gradual adoption!

+# QM Spider Symbol Search Test
+
+## How the Spider Search Works
+
+The spider search is a recursive symbol discovery system that explores the QM API systematically:
+
+### 1. Root Job (Weekly Schedule)
+```typescript
+// Triggered every Saturday at midnight
+@ScheduledOperation('spider-symbol-search', '0 0 * * 6', {...})
+
+// Creates 26 jobs: A, B, C, ... Z
+input: { prefix: null, depth: 0, maxDepth: 4 }
+```
+
+### 2. Level 1 - Single Letters (A-Z)
+```typescript
+// Each job searches for symbols starting with that letter
+input: { prefix: 'A', depth: 1, maxDepth: 4 }
+
+// If 10+ symbols found, creates: AA, AB, AC, ... AZ
+```
+
+### 3. Level 2 - Two Letters (AA-ZZ)
+```typescript
+// Searches for symbols starting with two letters
+input: { prefix: 'AA', depth: 2, maxDepth: 4 }
+
+// If 10+ symbols found, creates: AAA, AAB, AAC, ... AAZ
+```
+
+### 4. Level 3 & 4 - Deeper Search
+Continues until `maxDepth` is reached or fewer than 10 symbols are found.
+
+## Testing the Spider
+
+### Manual Test - Root Job
+```bash
+# Trigger spider search root job
+curl -X POST http://localhost:3000/api/handlers/qm/operations/spider-symbol-search \
+  -H "Content-Type: application/json" \
+  -d '{}'
+```
+
+### Manual Test - Specific Prefix
+```bash
+# Search for symbols starting with "APP"
+curl -X POST http://localhost:3000/api/handlers/qm/operations/spider-symbol-search \
+  -H "Content-Type: application/json" \
+  -d '{"prefix": "APP", "depth": 3, "maxDepth": 4}'
+```
+
+### Direct Symbol Search
+```bash
+# Search for specific symbols
+curl -X POST http://localhost:3000/api/handlers/qm/operations/search-symbols \
+  -H "Content-Type: application/json" \
+  -d '{"query": "AAPL"}'
+```
+
+## Optimization Features
+
+1. **Intelligent Branching**: Only creates child jobs if 10+ symbols found
+2. **Priority Management**: Deeper searches get lower priority
+3. **Staggered Execution**: Jobs are delayed to avoid API rate limits
+4. **Session Management**: Uses QM sessions with failure tracking
+5. **Caching**: Results cached for 30 minutes to avoid duplicate API calls
+
+## MongoDB Collections
+
+- `qm_symbols`: Stores discovered symbols with metadata
+- `qm_exchanges`: Stores unique exchanges found during searches
+
+## Monitoring
+
+Check logs for:
+- "Spider symbol search" - Job execution
+- "Created root spider jobs" - Initial A-Z creation
+- "Stored symbols from spider search" - Successful symbol storage
+- "Found X symbols for Y, queued Z child jobs" - Branching decisions

+# Data Sync Service
+
+The Data Sync Service handles synchronization of raw MongoDB data to PostgreSQL master records, providing a unified data layer for the stock-bot application.
+
+## Features
+
+### Original Sync Manager
+- Basic QM (QuoteMedia) symbol and exchange synchronization
+- Simple static exchange mapping
+- Manual sync triggers via REST API
+
+### Enhanced Sync Manager ✨ NEW
+- **Multi-provider support**: Syncs from EOD, Interactive Brokers, and QuoteMedia
+- **Comprehensive exchange handling**: Leverages all 4 MongoDB exchange collections
+- **Intelligent exchange mapping**: Dynamic mapping with fallback logic
+- **Transaction safety**: Full ACID compliance with rollback on errors
+- **Performance optimization**: Exchange caching for faster lookups
+- **Enhanced error handling**: Detailed error tracking and reporting
+
+## API Endpoints
+
+### Health Check
+- `GET /health` - Service health status
+
+### Original Sync Operations
+- `POST /sync/symbols` - Sync QM symbols to PostgreSQL
+- `POST /sync/exchanges` - Sync QM exchanges to PostgreSQL
+- `GET /sync/status` - Get basic sync status
+
+### Enhanced Sync Operations ✨ NEW
+- `POST /sync/exchanges/all?clear=true` - Comprehensive exchange sync from all providers (clear=true removes dummy data first)
+- `POST /sync/symbols/:provider?clear=true` - Sync symbols from specific provider (qm, eod, ib)
+- `POST /sync/clear` - Clear all PostgreSQL data (exchanges, symbols, mappings)
+- `GET /sync/status/enhanced` - Get detailed sync status
+- `GET /sync/stats/exchanges` - Get exchange statistics
+
+## Data Sources
+
+### MongoDB Collections
+1. **exchanges** (34 records) - Unified exchange reference
+2. **eodExchanges** (78 records) - EOD provider with currency/MIC data
+3. **ibExchanges** (214 records) - Interactive Brokers with asset types
+4. **qmExchanges** (25 records) - QuoteMedia exchanges
+
+### PostgreSQL Tables
+1. **master_exchanges** - Unified exchange master data
+2. **master_symbols** - Symbol master records
+3. **provider_symbol_mappings** - Multi-provider symbol mappings
+4. **sync_status** - Synchronization tracking
+
+## Key Improvements
+
+### 1. Multi-Provider Exchange Sync
+Instead of only syncing QM exchanges, the enhanced sync manager:
+- Syncs from EOD exchanges (comprehensive global data with currencies)
+- Adds IB exchanges for additional coverage (214 exchanges vs 25 in QM)
+
+### 2. Intelligent Exchange Mapping
+Replaces hard-coded mapping with dynamic resolution:
+```typescript
+// Before: Static mapping
+const exchangeMap = { 'NASDAQ': 'NASDAQ', 'NYSE': 'NYSE' };
+
+// After: Dynamic mapping with variations
+const codeMap = {
+  'NASDAQ': 'NASDAQ', 'NAS': 'NASDAQ',
+  'NYSE': 'NYSE', 'NYQ': 'NYSE',
+  'LSE': 'LSE', 'LON': 'LSE', 'LN': 'LSE',
+  'US': 'NYSE' // EOD uses 'US' for US markets
+};
+```
+
+### 3. Transaction Safety
+All sync operations use database transactions:
+- `BEGIN` transaction at start
+- `COMMIT` on success
+- `ROLLBACK` on any error
+- Ensures data consistency
+
+### 4. Performance Optimization
+- Exchange cache preloaded at startup
+- Reduced database queries during symbol processing
+- Batch operations where possible
+
+### 5. Enhanced Error Handling
+- Detailed error logging with context
+- Separate error counting in sync results
+- Graceful handling of missing/invalid data
+
+## Usage Examples
+
+### Clear All Data and Start Fresh Exchange Sync
+```bash
+curl -X POST "http://localhost:3005/sync/exchanges/all?clear=true"
+```
+
+### Sync Symbols from Specific Provider
+```bash
+# Sync QuoteMedia symbols (clear existing symbols first)
+curl -X POST "http://localhost:3005/sync/symbols/qm?clear=true"
+
+# Sync EOD symbols
+curl -X POST http://localhost:3005/sync/symbols/eod
+
+# Sync Interactive Brokers symbols
+curl -X POST http://localhost:3005/sync/symbols/ib
+```
+
+### Clear All PostgreSQL Data
+```bash
+curl -X POST http://localhost:3005/sync/clear
+```
+
+### Get Enhanced Status
+```bash
+curl http://localhost:3005/sync/status/enhanced
+curl http://localhost:3005/sync/stats/exchanges
+```
+
+## Configuration
+
+### Environment Variables
+- `DATA_SYNC_SERVICE_PORT` - Service port (default: 3005)
+- `NODE_ENV` - Environment mode
+
+### Database Connections
+- **MongoDB**: `mongodb://trading_admin:trading_mongo_dev@localhost:27017/stock?authSource=admin`
+- **PostgreSQL**: `postgresql://trading_user:trading_pass_dev@localhost:5432/trading_bot`

+Enhanced Sync Manager
+- Exchange caching
+- Dynamic mapping
+- Transaction safety
+- Multi-provider support
+```
+
+## Migration Path
+
+The enhanced sync manager is designed to work alongside the original sync manager:
+
+1. **Immediate**: Use enhanced exchange sync for better coverage
+2. **Phase 1**: Test enhanced symbol sync with each provider
+3. **Phase 2**: Replace original sync manager when confident
+4. **Phase 3**: Remove original sync manager and endpoints
+
+Both managers can be used simultaneously during the transition period.

+# Migration Guide: Modular Architecture
+
+This guide explains how to migrate from the current monolithic structure to the new modular architecture.
+
+## Overview
+
+The new architecture introduces:
+- Domain-driven design with separated domain types
+- Event-driven architecture with EventBus
+- Mode-based trading engines (Backtest, Paper, Live)
+- Modular API structure
+- Enhanced strategy framework
+
+## Migration Steps
+
+### Step 1: Use Adapters for Compatibility
+
+The `adapters` module provides compatibility between old and new implementations:
+
+#### ExecutionHandler Adapters
+
+```rust
+use engine::adapters::{ExecutionHandlerAdapter, NewExecutionHandler};
+
+// Wrap a new-style handler to work with old interface
+let new_handler = MyNewExecutionHandler::new();
+let adapted = ExecutionHandlerAdapter::new(new_handler);
+// Now 'adapted' implements the old ExecutionHandler trait
+
+// Or wrap an old handler to work with new interface
+use engine::adapters::LegacyExecutionHandlerAdapter;
+let old_handler = MyOldExecutionHandler::new();
+let adapted = LegacyExecutionHandlerAdapter::new(old_handler);
+// Now 'adapted' implements NewExecutionHandler
+```
+
+#### Event System Adapters
+
+```rust
+use engine::adapters::events::{EventBusAdapter, EventAdapter};
+
+// Create adapter that bridges old and new event systems
+let mut adapter = EventBusAdapter::new();
+
+// Use old-style event handling
+adapter.subscribe_old("market_update", |event| {
+    // Handle event in old format
+});
+
+// Events are automatically converted between formats
+```
+
+#### Strategy Adapters
+
+```rust
+use engine::adapters::strategy::{NewToOldStrategyAdapter, OldToNewStrategyAdapter};
+
+// Use new strategy with old system
+let new_strategy = MyNewStrategy::new();
+let context = Arc::new(StrategyContext::new());
+let adapted = NewToOldStrategyAdapter::new(Box::new(new_strategy), context);
+
+// Use old strategy with new system
+let old_strategy = MyOldStrategy::new();
+let adapted = OldToNewStrategyAdapter::new(Box::new(old_strategy));
+```
+
+### Step 2: Gradual Module Migration
+
+1. **Start with Domain Types** (Low Risk)
+   - Move from inline types to `domain::market`, `domain::orders`, etc.
+   - These are mostly data structures with minimal behavior
+
+2. **Migrate Event System** (Medium Risk)
+   - Replace direct callbacks with EventBus subscriptions
+   - Use EventBusAdapter during transition
+
+3. **Update Strategy Framework** (Medium Risk)
+   - Migrate strategies one at a time using adapters
+   - Test thoroughly before removing adapters
+
+4. **Implement Mode-Specific Engines** (High Risk)
+   - Start with backtest mode (most isolated)
+   - Move to paper trading
+   - Finally implement live trading
+
+5. **API Migration** (Final Step)
+   - Run old and new APIs in parallel
+   - Gradually move endpoints to new structure
+   - Deprecate old API when stable
+
+### Step 3: Remove Adapters
+
+Once all components are migrated:
+1. Remove adapter usage
+2. Delete old implementations
+3. Remove adapter modules
+
+## Testing Strategy
+
+1. **Unit Tests**: Test adapters ensure compatibility
+2. **Integration Tests**: Verify old and new systems work together
+3. **Regression Tests**: Ensure no functionality is lost
+4. **Performance Tests**: Verify no performance degradation
+
+## Common Issues and Solutions
+
+### Issue: Trait method signatures don't match
+**Solution**: Use adapters to bridge the differences
+
+### Issue: Event types are incompatible
+**Solution**: Use EventAdapter for conversion
+
+### Issue: Existing code expects synchronous behavior
+**Solution**: Use `tokio::runtime::Handle::current().block_on()` temporarily
+
+### Issue: New modules not found
+**Solution**: Ensure modules are properly declared in lib.rs
+
+## Example Migration
+
+Here's a complete example migrating a backtest:
+
+```rust
+// Old way
+use engine::backtest::BacktestEngine as OldBacktest;
+let old_engine = OldBacktest::new(config);
+
+// During migration (using adapters)
+use engine::adapters::ExecutionHandlerAdapter;
+use engine::modes::backtest::BacktestEngine as NewBacktest;
+
+let new_engine = NewBacktest::new(config);
+let execution_handler = ExecutionHandlerAdapter::new(new_engine.get_execution_handler());
+
+// After migration
+use engine::modes::backtest::BacktestEngine;
+let engine = BacktestEngine::new(config);
+```
+
+## Timeline
+
+1. **Week 1-2**: Implement and test adapters
+2. **Week 3-4**: Migrate domain types and events
+3. **Week 5-6**: Migrate strategies and modes
+4. **Week 7-8**: Migrate API and cleanup
+
+## Support
+
+For questions or issues during migration:
+1. Check adapter documentation
+2. Review test examples
+3. Consult team lead for architectural decisions

+# Orchestrator Architecture Improvements
+
+## Overview
+
+The orchestrator has been refactored to use the new Rust-based Technical Analysis library and improve separation of concerns. The architecture now follows a modular design with clear responsibilities for each component.
+
+## Key Components
+
+### 1. Technical Analysis (Rust Core)
+- **Location**: `apps/stock/core/src/indicators/`
+- **Purpose**: High-performance indicator calculations
+- **Features**:
+  - 7 indicators: SMA, EMA, RSI, MACD, Bollinger Bands, Stochastic, ATR
+  - Both batch and incremental calculations
+  - Thread-safe, zero-copy implementations
+  - NAPI bindings for TypeScript access
+
+### 2. Indicator Management
+- **Component**: `IndicatorManager`
+- **Responsibilities**:
+  - Price history management
+  - Indicator calculation and caching
+  - Incremental indicator updates
+  - Cross-indicator analysis (crossovers, etc.)
+
+### 3. Position Management
+- **Component**: `PositionManager`
+- **Responsibilities**:
+  - Track open positions
+  - Calculate P&L (realized and unrealized)
+  - Position sizing algorithms
+  - Performance metrics tracking
+
+### 4. Risk Management
+- **Component**: `RiskManager`
+- **Responsibilities**:
+  - Enforce position limits
+  - Monitor drawdown
+  - Calculate risk metrics (VaR, Sharpe ratio)
+  - Daily loss limits
+  - Position sizing based on risk
+
+### 5. Signal Management
+- **Component**: `SignalManager`
+- **Responsibilities**:
+  - Rule-based signal generation
+  - Signal aggregation (weighted, majority, etc.)
+  - Signal filtering
+  - Historical signal tracking
+

+```
+
+## Strategy Implementation Pattern
+
+### Before (Monolithic)
+```typescript
+class SimpleStrategy extends BaseStrategy {
+  // Everything mixed together
+  updateIndicators() { /* calculate MAs inline */ }
+  generateSignal() { /* risk checks, position sizing, signal logic */ }
+  onOrderFilled() { /* position tracking inline */ }
+}
+```
+
+### After (Modular)
+```typescript
+class AdvancedStrategy extends BaseStrategy {
+  private indicatorManager: IndicatorManager;
+  private positionManager: PositionManager;
+  private riskManager: RiskManager;
+  private signalManager: SignalManager;
+  
+  updateIndicators(data) {
+    // Delegate to specialized manager
+    this.indicatorManager.updatePrice(data);
+  }
+  
+  generateSignal(data) {
+    // 1. Get indicators
+    const indicators = this.indicatorManager.prepareIndicators(symbol);
+    
+    // 2. Check risk
+    const riskCheck = this.riskManager.checkNewPosition(...);
+    
+    // 3. Generate signal
+    const signal = this.signalManager.generateSignal(...);
+    
+    // 4. Size position
+    const size = this.positionManager.calculatePositionSize(...);
+  }
+}
+```
+
+## Benefits
+
+### 1. Performance
+- Rust indicators are 10-100x faster than JavaScript
+- Efficient memory usage with rolling windows
+- Parallel computation support
+
+### 2. Maintainability
+- Clear separation of concerns
+- Reusable components
+- Easy to test individual pieces
+- Consistent interfaces
+
+### 3. Flexibility
+- Strategies can mix and match components
+- Easy to add new indicators
+- Multiple position sizing methods
+- Configurable risk limits
+
+### 4. Reliability
+- Type-safe interfaces
+- Error handling at each layer
+- Comprehensive logging
+- Performance metrics tracking
+
+## Migration Guide
+
+### Converting Existing Strategies
+
+1. **Replace inline calculations with IndicatorManager**:
+```typescript
+// Old
+const sma = this.calculateSMA(prices, period);
+
+// New
+const sma = this.indicatorManager.getSMA(symbol, period);
+```
+
+2. **Use PositionManager for tracking**:
+```typescript
+// Old
+this.positions.set(symbol, quantity);
+
+// New
+this.positionManager.updatePosition(trade);
+```
+
+3. **Add RiskManager checks**:
+```typescript
+// New - check before trading
+const riskCheck = this.riskManager.checkNewPosition(...);
+if (!riskCheck.allowed) return null;
+```
+
+4. **Use SignalManager for rules**:
+```typescript
+// Setup rules once
+this.signalManager.addRule(CommonRules.goldenCross('sma20', 'sma50'));
+
+// Generate signals
+const signal = this.signalManager.generateSignal(symbol, timestamp, indicators);
+```
+
+## Example Strategies
+
+### 1. SimpleMovingAverageCrossoverV2
+- Uses IndicatorManager for MA calculations
+- PositionManager for sizing
+- Clean separation of indicator updates and signal generation
+
+### 2. IndicatorBasedStrategy
+- Demonstrates incremental indicators
+- Uses SignalGenerator for multi-indicator signals
+- Shows batch analysis capabilities
+
+### 3. AdvancedMultiIndicatorStrategy
+- Full integration of all managers
+- Multiple signal rules with aggregation
+- Risk-based position sizing
+- Stop loss and take profit management
+
+## Next Steps
+
+### Immediate Improvements
+1. ✅ Implement TA library in Rust
+2. ✅ Create manager components
+3. ✅ Refactor existing strategies
+4. ✅ Add comprehensive tests
+
+### Future Enhancements
+1. **More Indicators**:
+   - Ichimoku Cloud
+   - Fibonacci retracements
+   - Volume-weighted indicators
+   
+2. **Advanced Risk Management**:
+   - Portfolio optimization
+   - Correlation analysis
+   - Dynamic position sizing
+   
+3. **Machine Learning Integration**:
+   - Feature extraction from indicators
+   - Signal strength prediction
+   - Adaptive rule weights
+   
+4. **Performance Optimization**:
+   - GPU acceleration for backtesting
+   - Distributed indicator calculation
+   - Real-time streaming optimizations
+
+## Configuration Examples
+
+### Basic Strategy
+```typescript
+{
+  strategy: 'SimpleMovingAverageCrossoverV2',
+  params: {
+    fastPeriod: 10,
+    slowPeriod: 20,
+    positionSizePct: 0.1
+  }
+}
+```
+
+### Advanced Strategy
+```typescript
+{
+  strategy: 'AdvancedMultiIndicatorStrategy',
+  params: {
+    // Indicators
+    fastMA: 20,
+    slowMA: 50,
+    rsiPeriod: 14,
+    
+    // Risk
+    riskPerTrade: 0.02,
+    maxPositions: 5,
+    maxDrawdown: 0.2,
+    
+    // Signals
+    signalAggregation: 'weighted',
+    minSignalStrength: 0.6,
+    
+    // Position sizing
+    positionSizing: 'risk',
+    useATRStops: true
+  }
+}
+```

+# Rust Core Enhancement Roadmap
+
+## Missing Components & Potential Additions
+
+### 1. **Order Management System (OMS)**
+Currently missing a comprehensive order lifecycle management system.
+
+```rust
+// Suggested additions to orders module
+pub struct OrderManager {
+    active_orders: DashMap<String, Order>,
+    order_history: Vec<OrderEvent>,
+    order_routes: HashMap<String, OrderRoute>,
+}
+
+pub enum OrderEvent {
+    Submitted { order_id: String, timestamp: DateTime<Utc> },
+    Acknowledged { order_id: String, broker_id: String },
+    PartialFill { order_id: String, fill: Fill },
+    Filled { order_id: String, avg_price: f64 },
+    Cancelled { order_id: String, reason: String },
+    Rejected { order_id: String, reason: String },
+    Modified { order_id: String, changes: OrderModification },
+}
+
+pub struct OrderModification {
+    quantity: Option<f64>,
+    price: Option<f64>,
+    stop_price: Option<f64>,
+}
+```
+
+### 2. **Advanced Order Types**
+Current order types are basic. Missing:
+
+```rust
+pub enum OrderType {
+    // Existing
+    Market,
+    Limit { price: f64 },
+    Stop { stop_price: f64 },
+    StopLimit { stop_price: f64, limit_price: f64 },
+    
+    // Missing
+    Iceberg { visible_quantity: f64, total_quantity: f64 },
+    TWAP { duration: Duration, slices: u32 },
+    VWAP { duration: Duration, participation_rate: f64 },
+    PeggedToMidpoint { offset: f64 },
+    TrailingStop { trail_amount: f64, trail_percent: Option<f64> },
+    OCO { order1: Box<Order>, order2: Box<Order> }, // One-Cancels-Other
+    Bracket { entry: Box<Order>, stop_loss: Box<Order>, take_profit: Box<Order> },
+}
+```
+
+### 3. **Portfolio Management**
+No portfolio-level analytics or optimization.
+
+```rust
+pub mod portfolio {
+    pub struct Portfolio {
+        positions: HashMap<String, Position>,
+        cash_balance: f64,
+        margin_used: f64,
+        buying_power: f64,
+    }
+    
+    pub struct PortfolioAnalytics {
+        pub fn calculate_beta(&self, benchmark: &str) -> f64;
+        pub fn calculate_correlation_matrix(&self) -> Matrix<f64>;
+        pub fn calculate_var(&self, confidence: f64, horizon: Duration) -> f64;
+        pub fn calculate_sharpe_ratio(&self, risk_free_rate: f64) -> f64;
+        pub fn calculate_sortino_ratio(&self, mar: f64) -> f64;
+        pub fn calculate_max_drawdown(&self) -> DrawdownInfo;
+    }
+    
+    pub struct PortfolioOptimizer {
+        pub fn optimize_weights(&self, constraints: Constraints) -> HashMap<String, f64>;
+        pub fn calculate_efficient_frontier(&self, points: usize) -> Vec<(f64, f64)>;
+        pub fn black_litterman(&self, views: Views) -> HashMap<String, f64>;
+        pub fn risk_parity(&self) -> HashMap<String, f64>;
+    }
+}
+```
+
+### 4. **Market Data Enhancements**
+Missing Level 2 data, options data, and advanced market data types.
+
+```rust
+pub enum MarketDataType {
+    // Existing
+    Quote(Quote),
+    Trade(Trade),
+    Bar(Bar),
+    
+    // Missing
+    Level2 { bids: Vec<PriceLevel>, asks: Vec<PriceLevel> },
+    Imbalance { buy_quantity: f64, sell_quantity: f64, ref_price: f64 },
+    AuctionData { indicative_price: f64, indicative_volume: f64 },

+```
+
+## Priority Recommendations
+
+### High Priority
+1. **Order Management System** - Critical for proper order lifecycle tracking
+2. **Portfolio Analytics** - Essential for multi-asset strategies
+3. **Execution Algorithms** - TWAP/VWAP for better execution
+4. **Advanced Order Types** - Bracket orders, trailing stops
+5. **Backtesting Enhancements** - Proper slippage and impact modeling
+
+### Medium Priority
+1. **Options Support** - If trading options
+2. **ML Integration** - Feature generation framework
+3. **Monitoring & Alerts** - Real-time system health
+4. **Data Persistence** - Proper storage layer
+5. **More Indicators** - Based on strategy needs
+
+### Low Priority
+1. **Compliance Engine** - Unless regulatory requirements
+2. **Multi-venue Support** - Unless using multiple brokers
+3. **Advanced Market Data** - Level 2, imbalance data
+
+## Implementation Approach
+
+1. **Modular Design**: Each component should be optional and pluggable
+2. **Trait-Based**: Continue using traits for extensibility
+3. **Performance First**: Maintain the current performance focus
+4. **Backward Compatible**: Don't break existing APIs
+5. **Incremental**: Add features based on actual needs
+
+The core is solid, but these additions would make it a comprehensive institutional-grade trading system!

+# Technical Analysis Library Documentation
+
+The stock-bot orchestrator includes a high-performance Technical Analysis (TA) library implemented in Rust with TypeScript bindings. This provides efficient calculation of common technical indicators for trading strategies.
+
+## Architecture
+
+The TA library consists of:
+1. **Rust Core**: High-performance indicator calculations in `apps/stock/core/src/indicators/`
+2. **NAPI Bindings**: TypeScript interfaces exposed through `@stock-bot/engine`
+3. **TypeScript Wrapper**: Convenient API in `orchestrator/src/indicators/TechnicalAnalysis.ts`
+
+## Available Indicators
+
+### Simple Moving Average (SMA)
+```typescript
+const sma = ta.sma(prices, period);
+```
+
+### Exponential Moving Average (EMA)
+```typescript
+const ema = ta.ema(prices, period);
+```
+
+### Relative Strength Index (RSI)
+```typescript
+const rsi = ta.rsi(prices, period); // Returns values 0-100
+```
+
+### MACD (Moving Average Convergence Divergence)
+```typescript
+const macd = ta.macd(prices, fastPeriod, slowPeriod, signalPeriod);
+// Returns: { macd: number[], signal: number[], histogram: number[] }
+```
+
+### Bollinger Bands
+```typescript
+const bb = ta.bollingerBands(prices, period, stdDev);
+// Returns: { upper: number[], middle: number[], lower: number[] }
+```
+
+### Stochastic Oscillator
+```typescript
+const stoch = ta.stochastic(high, low, close, kPeriod, dPeriod, smoothK);
+// Returns: { k: number[], d: number[] }
+```
+
+### Average True Range (ATR)
+```typescript
+const atr = ta.atr(high, low, close, period);
+```
+
+## Usage Examples
+
+### Basic Indicator Calculation
+```typescript
+import { TechnicalAnalysis } from '../src/indicators/TechnicalAnalysis';
+
+const ta = new TechnicalAnalysis();
+const prices = [100, 102, 101, 103, 105, 104, 106];
+
+// Calculate 5-period SMA
+const sma5 = ta.sma(prices, 5);
+console.log('SMA:', sma5);
+
+// Get latest value
+const latestSMA = TechnicalAnalysis.latest(sma5);
+```
+
+### Incremental Indicators for Streaming Data
+```typescript
+import { IncrementalIndicators } from '../src/indicators/TechnicalAnalysis';
+
+const indicators = new IncrementalIndicators();
+
+// Create indicators
+indicators.createSMA('fast', 10);
+indicators.createSMA('slow', 20);
+indicators.createRSI('rsi', 14);
+
+// Update with new price
+const newPrice = 105.50;
+const fastSMA = indicators.update('fast', newPrice);
+const slowSMA = indicators.update('slow', newPrice);
+const rsi = indicators.update('rsi', newPrice);
+
+// Get current values
+const currentRSI = indicators.current('rsi');
+```
+
+### Signal Generation
+```typescript
+import { SignalGenerator } from '../src/indicators/TechnicalAnalysis';
+
+const generator = new SignalGenerator();
+const signal = generator.generateSignals(
+  'AAPL',
+  {
+    close: closePrices,
+    high: highPrices,
+    low: lowPrices,
+    volume: volumes
+  },
+  Date.now()
+);
+
+if (signal.action === 'BUY' && signal.strength > 0.7) {
+  // Strong buy signal
+  console.log(`Buy signal: ${signal.reason}`);
+}
+```
+
+### Crossover Detection
+```typescript
+// Detect when fast MA crosses above slow MA
+if (TechnicalAnalysis.crossover(fastMA, slowMA)) {
+  console.log('Bullish crossover detected');
+}
+
+// Detect when fast MA crosses below slow MA
+if (TechnicalAnalysis.crossunder(fastMA, slowMA)) {
+  console.log('Bearish crossover detected');
+}
+```
+
+## Strategy Integration
+
+Example strategy using multiple indicators:
+
+```typescript
+import { BaseStrategy } from '../BaseStrategy';
+import { TechnicalAnalysis } from '../../indicators/TechnicalAnalysis';
+
+export class MultiIndicatorStrategy extends BaseStrategy {
+  private ta = new TechnicalAnalysis();
+  private priceHistory: number[] = [];
+
+  onMarketData(data: any): Order | null {
+    this.priceHistory.push(data.close);
+    
+    if (this.priceHistory.length < 50) return null;
+    
+    // Calculate indicators
+    const rsi = this.ta.rsi(this.priceHistory, 14);
+    const macd = this.ta.macd(this.priceHistory);
+    const bb = this.ta.bollingerBands(this.priceHistory);
+    
+    // Get latest values
+    const currentRSI = TechnicalAnalysis.latest(rsi);
+    const currentPrice = data.close;
+    const bbLower = TechnicalAnalysis.latest(bb.lower);
+    
+    // Generate signals
+    if (currentRSI < 30 && currentPrice < bbLower) {
+      // Oversold + price below lower band = BUY
+      return this.createOrder('market', 'buy', this.positionSize);
+    }
+    
+    return null;
+  }
+}
+```
+
+## Performance Considerations
+
+1. **Batch vs Incremental**: Use batch calculations for backtesting, incremental for live trading
+2. **Memory Management**: The Rust implementation uses efficient rolling windows
+3. **Thread Safety**: All Rust indicators are thread-safe
+4. **Error Handling**: Invalid parameters return errors rather than panicking
+
+## Testing
+
+Run the indicator tests:
+```bash
+bun run test:indicators
+```
+
+Run the usage examples:
+```bash
+bun run example:indicators
+```
+
+## Extending the Library
+
+To add a new indicator:
+
+1. Create Rust implementation in `apps/stock/core/src/indicators/[indicator_name].rs`
+2. Implement `Indicator` and optionally `IncrementalIndicator` traits
+3. Add NAPI bindings in `apps/stock/core/src/api/indicators.rs`
+4. Update TypeScript definitions in `apps/stock/core/index.d.ts`
+5. Add wrapper methods in `orchestrator/src/indicators/TechnicalAnalysis.ts`
+6. Write tests and examples
+
+## Common Patterns
+
+### Momentum Indicators
+- RSI < 30: Oversold
+- RSI > 70: Overbought
+- MACD crossover: Trend change
+
+### Volatility Indicators
+- Bollinger Band squeeze: Low volatility
+- ATR increase: Higher volatility
+
+### Trend Indicators
+- Price > SMA200: Long-term uptrend
+- EMA crossovers: Short-term trend changes
+
+### Combined Signals
+Best results often come from combining multiple indicators:
+- RSI oversold + MACD bullish crossover
+- Price at Bollinger lower band + Stochastic oversold
+- Volume confirmation with price indicators

+# Monitoring Components
+
+This directory contains monitoring components that have been refactored to use standardized UI components with a consistent dark theme.
+
+## Standardized Components
+
+### StatusBadge
+Used for displaying status indicators with consistent styling:
+- `ConnectionStatus` - Shows connected/disconnected state
+- `HealthStatus` - Shows healthy/unhealthy state  
+- `ServiceStatusIndicator` - Shows service status as a colored dot
+
+### MetricCard
+Displays metrics with optional progress bars in a consistent card layout.
+
+### Cards
+- `ServiceCard` - Displays individual service status
+- `DatabaseCard` - Displays database connection info
+- `SystemHealthCard` - Shows system health overview
+- `CacheStatsCard` - Shows cache statistics
+- `ProxyStatsCard` - Shows proxy status
+- `QueueStatsTable` - Displays queue statistics in a table
+
+## Theme Colors
+
+All components now use the standardized color palette from the Tailwind config:
+- Background: `bg-surface-secondary` (dark surfaces)
+- Borders: `border-border`
+- Text: `text-text-primary`, `text-text-secondary`, `text-text-muted`
+- Status colors: `text-success`, `text-danger`, `text-warning`
+- Primary accent: `text-primary-400`, `bg-primary-500/10`
+
+## Utilities
+
+Common formatting functions are available in `utils/formatters.ts`:
+- `formatUptime()` - Formats milliseconds to human-readable uptime
+- `formatBytes()` - Formats bytes to KB/MB/GB
+- `formatNumber()` - Adds thousand separators
+- `formatPercentage()` - Formats numbers as percentages

+# Monitoring Components - Spacing Guidelines
+
+This document outlines the standardized spacing used across monitoring components to maximize screen real estate.
+
+## Spacing Standards
+
+### Page Layout
+- Main container: `flex flex-col h-full space-y-4` (16px vertical gaps)
+- No outer padding - handled by parent layout
+- Section spacing: `space-y-4` between major sections
+
+### Cards
+- Card padding: `p-4` (16px) for main cards, `p-3` (12px) for compact cards
+- Card header: `pb-3` (12px bottom padding)
+- Card content spacing: `space-y-3` (12px gaps)
+- Grid gaps: `gap-3` (12px) or `gap-4` (16px)
+
+### Typography
+- Page title: `text-lg font-bold mb-2`
+- Section headings: `text-lg font-semibold mb-3`
+- Card titles: `text-base font-semibold`
+- Large values: `text-xl` or `text-lg`
+- Regular text: `text-sm`
+- Small text/labels: `text-xs`
+
+### Specific Components
+
+**ServiceCard**: `p-3` with `space-y-1.5` and `text-xs`
+**DatabaseCard**: `p-4` with `space-y-2`
+**SystemHealthCard**: `p-4` with `space-y-3`
+**CacheStatsCard**: `p-4` with `space-y-3`
+**ProxyStatsCard**: `p-4` with `space-y-3`
+**QueueStatsTable**: `p-4` with `text-xs` table
+
+### Grids
+- Service grid: `gap-3`
+- Database grid: `gap-3`
+- Main layout grid: `gap-4`
+
+## Benefits
+- Maximizes usable screen space
+- Consistent with dashboard/exchanges pages
+- More data visible without scrolling
+- Clean, compact appearance

+# Pipeline Page - Spacing Updates
+
+This document outlines the spacing standardization applied to the Pipeline page to match the monitoring and dashboard pages.
+
+## Changes Applied
+
+### Layout Structure
+- Main container: `flex flex-col h-full space-y-4`
+- No outer padding (handled by parent layout)
+- Flex-shrink-0 for fixed elements
+- Overflow-y-auto for scrollable content area
+
+### Typography
+- Page title: `text-lg` (from `text-2xl`)
+- Page description: `text-sm`
+- Section headings: `text-base` (from `text-lg`)
+- Card titles: `text-sm`
+- Card descriptions: `text-xs` (from `text-sm`)
+- All text in cards: `text-xs`
+
+### Spacing
+- Grid gaps: `gap-3` (from `gap-4`)
+- Card padding: `p-3` (from `p-4`)
+- Margins: `mb-2` or `mb-3` (from `mb-3` or `mb-4`)
+- Button padding: `px-2.5 py-1.5` (from `px-3 py-2`)
+
+### Icons
+- Section icons: `h-4 w-4` (from `h-5 w-5`)
+- Button icons: `h-3 w-3` (from `h-4 w-4`)
+
+### Specific Components
+
+**Stats Cards**:
+- Padding: `p-3`
+- Title: `text-base mb-2`
+- Content: `text-xs` with `space-y-1.5`
+
+**Operation Cards**:
+- Padding: `p-3`
+- Title: `text-sm`
+- Description: `text-xs mb-2`
+- Form elements: `text-xs` with `mb-2`
+
+**Buttons**:
+- Padding: `px-2.5 py-1.5`
+- Text: `text-xs`
+- Icons: `h-3 w-3`
+
+**Alert Messages**:
+- Padding: `p-3`
+- Text: `text-sm`
+- Icons: `h-4 w-4`
+
+## Benefits
+- Consistent with monitoring and dashboard pages
+- More operations visible without scrolling
+- Cleaner, more compact appearance
+- Better space utilization for data-heavy interface

+# Using the build script
+./scripts/build-images.sh
+
+# Or manually with docker-compose
+docker-compose build
+```
+
+### Run with Docker Compose
+
+```bash
+# Start all services

+
+# Stop services
+docker-compose down
+```
+
+### Production Docker Deployment
+
+1. **Set environment variables:**
+   ```bash
+   export API_JWT_SECRET=your-secret-key
+   export DATABASE_URL=postgresql://user:pass@host:5432/db
+   # ... other required variables
+   ```
+
+2. **Run with production config:**
+   ```bash
+   docker-compose -f docker-compose.yml up -d
+   ```
+
+## Kubernetes Deployment
+
+### Prerequisites
+
+- Kubernetes cluster (1.24+)
+- kubectl configured
+- Ingress controller installed
+- cert-manager (for TLS)
+
+### Deploy to Kubernetes
+
+```bash
+# Using the deploy script
+./scripts/deploy-k8s.sh
+
+# Or manually
+kubectl apply -f k8s/
+```
+
+### Configuration
+
+1. **Update secrets:**
+   ```bash
+   # Edit k8s/secrets.yaml with your values
+   # Then apply
+   kubectl apply -f k8s/secrets.yaml -n wcag-ada
+   ```
+
+2. **Update ingress hosts:**
+   ```bash
+   # Edit k8s/ingress.yaml
+   # Replace example.com with your domain
+   kubectl apply -f k8s/ingress.yaml -n wcag-ada
+   ```
+
+### Scaling
+
+```bash
+# Scale API replicas
+kubectl scale deployment wcag-ada-api --replicas=5 -n wcag-ada
+
+# Scale Worker replicas
+kubectl scale deployment wcag-ada-worker --replicas=3 -n wcag-ada
+```
+
+## GitLab CI/CD
+
+### Setup
+
+1. **Configure GitLab Container Registry:**
+   - Enable container registry in project settings
+   - Note your registry URL
+
+2. **Add CI/CD Variables:**
+   ```
+   CI_REGISTRY_USER     - GitLab username
+   CI_REGISTRY_PASSWORD - GitLab access token
+   KUBE_URL            - Kubernetes API URL (staging)
+   KUBE_TOKEN          - Kubernetes service account token (staging)
+   KUBE_URL_PROD       - Kubernetes API URL (production)
+   KUBE_TOKEN_PROD     - Kubernetes service account token (production)
+   ```
+
+3. **Configure environments:**
+   - Create `staging` and `production` environments in GitLab
+   - Set appropriate URLs
+
+### Deployment Flow
+
+1. **Development:**
+   - Push to `develop` branch
+   - Automatically builds and deploys to staging
+
+2. **Production:**
+   - Merge to `main` branch
+   - Builds images automatically
+   - Manual approval required for production deployment
+
+## Configuration Management
+
+### Environment Variables
+
+Key configuration variables:
+
+```bash
+# Application
+NODE_ENV=production
+APP_NAME=wcag-ada
+
+# API
+API_PORT=3001
+API_JWT_SECRET=<strong-secret>
+API_CORS_ORIGIN=https://your-domain.com
+
+# Database
+DATABASE_URL=postgresql://user:password@host:5432/wcag_ada
+
+# Redis
+REDIS_HOST=redis
+REDIS_PORT=6379
+REDIS_PASSWORD=<redis-password>
+
+# Worker
+WORKER_CONCURRENCY=5
+WORKER_QUEUE_NAME=accessibility-scans
+
+# Scanner
+SCANNER_HEADLESS=true
+SCANNER_TIMEOUT=30000
+```
+
+### Configuration Priority
+
+1. Command-line arguments (highest)
+2. Environment variables
+3. Configuration files
+4. Default values (lowest)
+
+### Secrets Management
+
+- **Development:** Use `.env` files
+- **Docker:** Use environment variables or Docker secrets
+- **Kubernetes:** Use Kubernetes secrets
+- **Production:** Consider using:
+  - HashiCorp Vault
+  - AWS Secrets Manager
+  - Azure Key Vault
+  - GitLab CI/CD variables
+
+## Monitoring & Maintenance
+
+### Health Checks
+
+All services expose health endpoints:
+
+- API: `http://api:3001/health`
+- Worker: `http://worker:3002/health`
+- Dashboard: `http://dashboard:8080/health`
+
+### Monitoring Stack
+
+Recommended monitoring setup:
+
+1. **Metrics:** Prometheus + Grafana
+2. **Logs:** ELK Stack or Loki
+3. **Traces:** Jaeger or Zipkin
+4. **Uptime:** Uptime Kuma or Pingdom
+
+### Database Maintenance
+
+```bash
+# Backup PostgreSQL
+kubectl exec -it postgres-pod -n wcag-ada -- pg_dump -U wcag_user wcag_ada > backup.sql
+
+# Backup Redis
+kubectl exec -it redis-pod -n wcag-ada -- redis-cli BGSAVE
+```
+
+### Updates and Migrations
+
+1. **Database migrations:**
+   ```bash
+   # Run migrations before deployment
+   kubectl run migration --rm -it --image=wcag-ada/api:latest -- bunx prisma migrate deploy
+   ```
+
+2. **Rolling updates:**
+   ```bash
+   # Update image
+   kubectl set image deployment/wcag-ada-api api=wcag-ada/api:new-version -n wcag-ada
+   
+   # Monitor rollout
+   kubectl rollout status deployment/wcag-ada-api -n wcag-ada
+   ```
+
+### Troubleshooting
+
+1. **View logs:**
+   ```bash
+   # Kubernetes
+   kubectl logs -f deployment/wcag-ada-api -n wcag-ada
+   
+   # Docker
+   docker-compose logs -f api
+   ```
+
+2. **Debug pods:**
+   ```bash
+   # Get pod details
+   kubectl describe pod <pod-name> -n wcag-ada
+   
+   # Execute commands in pod
+   kubectl exec -it <pod-name> -n wcag-ada -- /bin/sh
+   ```
+
+3. **Common issues:**
+   - Database connection: Check DATABASE_URL and network connectivity
+   - Redis connection: Verify Redis is running and accessible
+   - Browser issues: Ensure Chromium dependencies are installed
+   - Memory issues: Increase resource limits in Kubernetes
+
+## Security Considerations
+
+1. **Network Security:**
+   - Use NetworkPolicies in Kubernetes
+   - Implement proper firewall rules
+   - Use TLS for all external communications
+
+2. **Application Security:**
+   - Rotate JWT secrets regularly
+   - Use strong passwords for databases
+   - Implement rate limiting
+   - Enable CORS appropriately
+
+3. **Container Security:**
+   - Run containers as non-root user
+   - Use minimal base images
+   - Scan images for vulnerabilities
+   - Keep dependencies updated
+
+## Support
+
+For issues or questions:
+1. Check application logs
+2. Review health check endpoints
+3. Consult error messages in dashboard
+4. Check GitLab CI/CD pipeline status

+# WCAG-ADA Compliance Monitoring Platform
+
+An automated web accessibility compliance monitoring system that continuously scans websites for WCAG and ADA compliance issues, provides detailed reports, and offers remediation suggestions.
+
+## Architecture
+
+The platform consists of four main services:
+
+### 1. **Scanner Service** (`/scanner`)
+- Performs accessibility scans using axe-core and Playwright
+- Supports WCAG 2.0, 2.1, and 2.2 compliance levels (A, AA, AAA)
+- Generates detailed violation reports with fix suggestions
+- Captures screenshots of accessibility issues
+
+### 2. **API Service** (`/api`)
+- RESTful API built with Hono framework
+- JWT-based authentication
+- Redis-backed rate limiting
+- PostgreSQL database with Prisma ORM
+- BullMQ integration for job queuing
+
+### 3. **Worker Service** (`/worker`)
+- Processes scan jobs from the queue
+- Runs scheduled scans based on website configurations
+- Handles scan result processing and storage
+- Provides health monitoring endpoints
+
+### 4. **Dashboard** (`/dashboard`)
+- React 18 SPA with Vite
+- Real-time scan monitoring
+- Compliance reporting and analytics
+- Website and scan management
+- Built with TailwindCSS and Radix UI
+
+## Configuration
+
+The application uses a sophisticated configuration system that loads settings from multiple sources:
+
+1. Default values (defined in schemas)
+2. Configuration files (`.env`, `config.json`)
+3. Environment variables
+4. Command-line arguments
+
+### Key Configuration Files
+
+- `/config/src/schemas/` - Zod schemas defining all configuration options
+- `/config/src/config-instance.ts` - Main configuration loader
+- `.env` - Environment-specific settings
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js 18+
+- PostgreSQL
+- Redis
+- Bun (recommended) or npm/yarn
+
+### Installation
+
+1. Install dependencies:
+```bash
+bun install
+```
+
+2. Set up the database:
+```bash
+cd apps/wcag-ada/api
+bunx prisma migrate dev
+```
+
+3. Configure environment variables:
+```bash
+cp .env.example .env
+# Edit .env with your settings
+```
+
+### Running Services
+
+Start all services concurrently:
+```bash
+bun run dev
+```
+
+Or run individual services:
+
+```bash
+# API
+cd apps/wcag-ada/api
+bun run dev
+
+# Worker
+cd apps/wcag-ada/worker
+bun run dev
+
+# Dashboard
+cd apps/wcag-ada/dashboard
+bun run dev
+
+# Scanner (for testing)
+cd apps/wcag-ada/scanner
+bun run example
+```
+
+## API Endpoints
+
+### Authentication
+- `POST /api/auth/register` - Register new user
+- `POST /api/auth/login` - User login
+- `GET /api/auth/me` - Get current user
+
+### Websites
+- `GET /api/websites` - List user's websites
+- `POST /api/websites` - Add new website
+- `PUT /api/websites/:id` - Update website
+- `DELETE /api/websites/:id` - Delete website
+
+### Scans
+- `POST /api/scans` - Start new scan
+- `GET /api/scans/:id` - Get scan status
+- `GET /api/scans/:id/result` - Get scan results
+- `GET /api/scans/:id/violations` - Get violations
+- `DELETE /api/scans/:id` - Cancel scan
+
+### Reports
+- `GET /api/reports/compliance/:websiteId` - Get compliance report
+- `GET /api/reports/trends/:websiteId` - Get trend analysis
+
+### Health
+- `GET /health` - Service health check
+- `GET /health/stats` - Detailed statistics
+

+# WCAG-ADA Configuration
+
+Centralized configuration management for the WCAG-ADA compliance platform, built on top of the core configuration system.
+
+## Overview
+
+This configuration system provides:
+- Type-safe configuration with Zod schemas
+- Multi-source configuration (JSON files + environment variables)
+- Environment-specific overrides
+- Service-specific configurations
+- Feature flags management
+
+## Usage
+
+### Basic Usage
+
+```typescript
+import { initializeWcagConfig, getWcagConfig } from '@wcag-ada/config';
+
+// Initialize configuration (do this once at app startup)
+const config = initializeWcagConfig('api'); // 'api' | 'dashboard' | 'worker'
+
+// Access configuration values
+console.log(config.services.api.port); // 3001
+console.log(config.scanner.concurrency); // 2
+```
+
+### Helper Functions
+
+```typescript
+import { 
+  getScannerConfig,
+  getWorkerConfig,
+  isFeatureEnabled,
+  getServiceConfig
+} from '@wcag-ada/config';
+
+// Get specific configurations
+const scannerConfig = getScannerConfig();
+const workerConfig = getWorkerConfig();
+
+// Check feature flags
+if (isFeatureEnabled('screenshots')) {
+  // Screenshot feature is enabled
+}
+
+if (isFeatureEnabled('reports.pdf')) {
+  // PDF reports are enabled
+}
+
+// Get service configuration
+const apiConfig = getServiceConfig('api');
+```
+
+## Configuration Structure
+
+### Scanner Configuration
+- `concurrency`: Number of concurrent scans (1-10)
+- `timeout`: Maximum scan duration
+- `headless`: Run browser in headless mode
+- `blockResources`: Block images/fonts for faster scans
+- `viewport`: Default viewport dimensions
+
+### Worker Configuration
+- `concurrency`: Number of concurrent jobs
+- `queueName`: BullMQ queue name
+- `redis`: Redis connection settings
+- `jobs`: Job-specific configurations
+- `scheduler`: Scheduled job settings
+
+### Features Configuration
+- `screenshots`: Screenshot capture settings
+- `customRules`: Custom accessibility rules
+- `multiPage`: Multi-page scanning
+- `reports`: Report generation features
+- `integrations`: External service integrations
+- `enterprise`: Enterprise features (SSO, white-label)
+
+### Providers Configuration
+- `storage`: File storage (local, S3, GCS, Azure)
+- `email`: Email providers (SMTP, SendGrid, SES)
+- `auth`: Authentication settings (JWT, OAuth)
+- `analytics`: Analytics providers
+- `cdn`: CDN configuration
+
+## Environment Variables
+
+The system supports environment variable overrides with the `WCAG_` prefix:
+
+```bash
+# Scanner settings
+WCAG_SCANNER_CONCURRENCY=5
+WCAG_SCANNER_TIMEOUT=180000
+WCAG_SCANNER_HEADLESS=true
+
+# Worker settings
+WCAG_WORKER_CONCURRENCY=3
+WCAG_WORKER_REDIS_HOST=redis.example.com
+WCAG_WORKER_REDIS_PORT=6379
+
+# Service ports
+WCAG_SERVICES_API_PORT=3001
+WCAG_SERVICES_DASHBOARD_PORT=3000
+
+# Storage
+WCAG_PROVIDERS_STORAGE_TYPE=s3
+WCAG_PROVIDERS_STORAGE_S3_BUCKET=wcag-ada-storage
+WCAG_PROVIDERS_STORAGE_S3_REGION=us-east-1
+
+# Authentication
+WCAG_PROVIDERS_AUTH_JWT_SECRET=your-secret-key
+```
+
+## Configuration Files
+
+Configuration files are loaded in this order (later files override earlier ones):
+1. `config/default.json` - Base configuration
+2. `config/{environment}.json` - Environment-specific (development, production, test)
+3. Environment variables - Highest priority
+
+## Service-Specific Configuration
+
+Each service can have its own configuration:
+
+```typescript
+// API Service
+initializeWcagConfig('api');
+// Uses services.api configuration
+
+// Dashboard
+initializeWcagConfig('dashboard');
+// Uses services.dashboard configuration
+
+// Worker
+initializeWcagConfig('worker');
+// Uses services.worker configuration
+```
+
+## Adding New Configuration
+
+1. Add schema definition in `src/schemas/`
+2. Update `wcag-app.schema.ts` to include new schema
+3. Add default values in `config/default.json`
+4. Add environment-specific overrides as needed
+5. Create helper functions in `src/index.ts` for easy access
+
+## Examples
+
+### Check Subscription Limits
+
+```typescript
+import { getSubscriptionConfig } from '@wcag-ada/config';
+
+const starterLimits = getSubscriptionConfig('starter');
+console.log(starterLimits.websites); // 5
+console.log(starterLimits.scansPerMonth); // 500
+```
+
+### Get Compliance Settings
+
+```typescript
+import { getComplianceConfig } from '@wcag-ada/config';
+
+const compliance = getComplianceConfig();
+console.log(compliance.defaultLevel); // { standard: 'WCAG21', level: 'AA' }
+console.log(compliance.criticalCriteria); // ['1.1.1', '1.3.1', ...]
+```
+
+### Storage Configuration
+
+```typescript
+import { getStorageConfig } from '@wcag-ada/config';
+
+const storage = getStorageConfig();
+if (storage.type === 's3') {
+  // Use S3 storage
+} else {
+  // Use local storage
+}
+```

+# WCAG-ADA Accessibility Scanner
+
+A high-performance accessibility scanner built with Playwright and axe-core for WCAG compliance testing.
+
+## Features
+
+- 🚀 Fast scanning with Playwright
+- ♿ WCAG 2.0, 2.1, and 2.2 compliance testing
+- 📊 Detailed violation reports with fix suggestions
+- 📸 Screenshot capture for violations
+- 🔐 Authentication support (basic, form-based, custom)
+- 📱 Mobile and desktop viewport testing
+- 🎯 Custom rule support
+- 🚫 Resource blocking for faster scans
+
+## Installation
+
+```bash
+bun install
+```
+
+## Usage
+
+### Basic Example
+
+```typescript
+import { AccessibilityScanner } from '@wcag-ada/scanner';
+
+const scanner = new AccessibilityScanner();
+await scanner.initialize();
+
+const result = await scanner.scan({
+  url: 'https://example.com',
+  wcagLevel: {
+    level: 'AA',
+    version: '2.1'
+  }
+});
+
+console.log(`Compliance Score: ${result.summary.score}%`);
+console.log(`Violations Found: ${result.summary.violationCount}`);
+
+await scanner.close();
+```
+
+### Advanced Options
+
+```typescript
+const result = await scanner.scan({
+  url: 'https://example.com',
+  wcagLevel: {
+    level: 'AA',
+    version: '2.1'
+  },
+  includeScreenshots: true,
+  viewport: {
+    width: 1920,
+    height: 1080,
+    isMobile: false
+  },
+  authenticate: {
+    type: 'form',
+    loginUrl: 'https://example.com/login',
+    credentials: {
+      username: 'user@example.com',
+      password: 'password'
+    },
+    selectors: {
+      username: '#email',
+      password: '#password',
+      submit: 'button[type="submit"]'
+    }
+  },
+  excludeSelectors: [
+    '.cookie-banner',
+    '[aria-hidden="true"]'
+  ],
+  waitForSelector: '#main-content',
+  timeout: 60000
+});
+```
+
+### Scan Multiple Pages
+
+```typescript
+const urls = [
+  'https://example.com',
+  'https://example.com/about',
+  'https://example.com/contact'
+];
+
+const results = await scanner.scanMultiplePages(urls, {
+  wcagLevel: { level: 'AA', version: '2.1' }
+});
+```
+
+## Scan Results
+
+The scanner returns a comprehensive `AccessibilityScanResult` object containing:
+
+- **Summary**: Overall compliance score, violation counts by severity
+- **Violations**: Detailed list of accessibility issues with:
+  - Impact level (critical, serious, moderate, minor)
+  - Affected elements with HTML snippets
+  - Fix suggestions
+  - WCAG criteria mapping
+  - Screenshots (if enabled)
+- **Passes**: Rules that passed
+- **Incomplete**: Rules that need manual review
+- **Page Metadata**: Title, language, element counts, landmark presence
+- **WCAG Compliance**: Level-specific compliance status
+
+## Performance Optimization
+
+The scanner is optimized for speed:
+- Blocks unnecessary resources (images, fonts, analytics)
+- Parallel page scanning support
+- Configurable timeouts
+- Headless browser mode
+
+## Custom Rules
+
+Add custom accessibility rules:
+
+```typescript
+const customRules = [{
+  id: 'custom-button-size',
+  selector: 'button',
+  tags: ['custom', 'wcag21aa'],
+  description: 'Buttons must have minimum touch target size',
+  help: 'Ensure buttons are at least 44x44 pixels',
+  severity: 'serious',
+  validator: (element) => {
+    const rect = element.getBoundingClientRect();
+    return rect.width >= 44 && rect.height >= 44;
+  }
+}];
+
+const result = await scanner.scan({
+  url: 'https://example.com',
+  customRules
+});
+```
+
+## Running the Example
+
+```bash
+bun run src/example.ts
+```
+
+## Development
+
+```bash
+# Build
+bun run build
+
+# Watch mode
+bun run dev
+
+# Type checking
+bun run typecheck
+```

+I'll search for specific information about Timothy Masters' recommendations on permutation tests for trading and newer alternatives in 2025.Based on my research, here's a comprehensive overview of **Timothy Masters' recommendations and newer alternatives for permutation and randomization tests in trading (2025)**:
+
+## Timothy Masters' Permutation Test Recommendations
+
+Timothy Masters, in his book "Permutation and Randomization Tests for Trading System Development," advocates for several key permutation tests:
+
+### 1. **Core Permutation Methods**
+The book covers: Testing for overfitting at the earliest possible stage, Evaluating the luckiness-versus-skill of a fully developed system before deploying it, Testing the effectiveness and reliability of a trading system factory, Removing selection bias when screening a large number of indicators
+
+### 2. **Monte Carlo Permutation Test**
+The Monte Carlo permutation test of Timothy Masters involves simulating multiple iterations of the strategy using randomly permuted versions of historical data. The process:
+- Transforms absolute prices into log-returns for better statistical properties
+- Creates 500 or 1000 permuted versions resulting in worse performance for >>90% if the strategy picks up a real "signal"
+
+### 3. **Key Applications**
+One usage of the Monte Carlo Permutation test allows us to discover the degree of data overfitting, without using the out-of-sample data
+- Tests whether trading performance beats 99% of what could be expected by luck
+- Preserves the single-usage principle of out-of-sample data
+- If our trading system beats 99% of what can be expected by good luck, we can conclude that our indicator, trading system or trading system development method is actually worthwhile
+
+### 4. **Selection Bias Testing**
+On March 30, 2020, I released a third edition of the book which includes an important new section that introduces an alternative permutation test for selection bias that is substantially superior to the traditional test
+
+## Newer Alternatives and Advances in 2025
+
+### 1. **System Parameter Permutation (SPP) and Randomization (SPR)**
+System Parameter Randomization (SPR) is introduced as a close cousin of SPP to address computational limitations and provide a better alternative
+
+**Advantages over Masters' approach:**
+- The idea behind System Parameter Permutation is that we must test ALL the possible parameter combinations and only from the data of all optimization runs we can make some assumptions about the realistic strategy performance
+- Computes median values for all performance statistics (Net profit, Drawdown, Sharpe ratio, etc.)
+- More computationally feasible for complex trading systems
+
+### 2. **Advanced Bootstrap Methods**
+
+**Block Bootstrap Variants:**
+Advanced block bootstrap methods are specifically tailored for dependent time series data, including stationary bootstrap, circular bootstrap, and tapered block bootstrap
+- **Stationary Bootstrap**: Uses random block lengths from geometric distribution
+- **Circular Bootstrap**: Attempts to solve edge effects by wrapping the series
+- **Tapered Block Bootstrap**: Offers smoother transitions at block boundaries
+
+### 3. **White's Reality Check and Hansen's SPA Test**
+White's Reality Check bootstrap methodology evaluates simple technical trading rules while quantifying the data-snooping bias
+
+**Superior Predictive Ability (SPA) Test:**
+- The stepwise SPA test is more powerful than the stepwise Reality Check test of Romano and Wolf
+- Addresses data snooping bias more effectively
+- Can identify predictive models without potential bias
+
+### 4. **Conformal Prediction for Trading**
+
+This is one of the most promising newer alternatives:
+
+**Key Features:**
+- Distribution-free nature - unlike Bayesian approaches and other statistical methods that require specific assumptions about the data distribution, conformal prediction makes no such assumptions
+- Provides valid prediction intervals with guaranteed coverage
+- The EnbPI (Ensemble batch Prediction Intervals) method removes the data exchangeability requirement and can thus be applied in time series forecasting
+
+**Applications in Trading:**
+- Uncertainty quantification for price predictions
+- Risk-adjusted position sizing based on prediction intervals
+- Model confidence assessment without distributional assumptions
+
+### 5. **Synthetic Data Generation Methods**
+
+Deep generative models produce synthetic time-series data, enhancing the amount of data available for training predictive models
+
+**Benefits for Trading Strategy Validation:**
+- Creates realistic market scenarios while preserving statistical properties
+- Synthetic data obtained this way replicates the distribution properties of real historical data, leads to better performance, and enables thorough validation of predictive models
+- Addresses data scarcity issues in certain market conditions
+- In the finance sector, synthetic data is used for fraud detection, risk assessment, and algorithmic trading
+
+### 6. **Hybrid Approaches**
+
+**Combining Multiple Methods:**
+The variance test takes the historical trades and creates a probable distribution to resample, selecting random trades from this distribution until it reaches the backtest's total trade count
+
+**Modern Robustness Tests:**
+- Noise testing, Vs Shifted, Variance testing or Monte Carlo Permutation test multiple price paths
+- Address limitations of traditional walk-forward analysis
+- Four-step approach: in-sample excellence, Monte Carlo permutation testing, walk-forward testing, and walk-forward Monte Carlo testing
+
+## Key Advantages of Newer Methods
+
+1. **Computational Efficiency**: Modern methods like SPR and conformal prediction are more computationally efficient than exhaustive permutation testing
+
+2. **Better Coverage**: CopulaCPTS produces significantly sharper and more calibrated uncertainty estimates than state-of-the-art baselines
+
+3. **No Distributional Assumptions**: Conformal prediction and synthetic data methods work without assuming specific data distributions
+
+4. **Adaptive Capabilities**: Methods like EnbPI update intervals as new data arrives, maintaining adaptiveness
+
+5. **Multi-Path Testing**: Unlike single-path methods, newer approaches test multiple possible market scenarios simultaneously
+
+## Recommendations for 2025
+
+For modern trading system development, consider:
+
+1. **Start with Masters' Monte Carlo Permutation** for basic validation
+2. **Implement SPP/SPR** for parameter robustness testing
+3. **Use Conformal Prediction** for uncertainty quantification and risk management
+4. **Apply Synthetic Data Generation** for stress testing under various market conditions
+5. **Combine multiple methods** for comprehensive validation
+
+The field has evolved significantly, with newer methods offering better computational efficiency, fewer assumptions, and more robust validation while maintaining the core principles that Masters established.

-# Cache Library Usage Guide
-
-> **⚠️ DEPRECATED**: This documentation is outdated. The cache library has been simplified to only use Redis/Dragonfly.
-> 
-> **Please see [simplified-cache-usage.md](./simplified-cache-usage.md) for current usage instructions.**
-
-The `@stock-bot/cache` library now provides a simplified Redis-only caching solution designed specifically for trading bot applications.
-
-## Migration from Old API
-
-If you're migrating from the old cache API, here are the key changes:
-
-### Old API (DEPRECATED)
-```typescript
-// These are no longer supported
-const cache = createCache('auto');
-const cache = createCache('memory');  
-const cache = createCache('hybrid');
-const cache = createCache('redis');
-
-// Direct imports no longer available
-import { MemoryCache, HybridCache } from '@stock-bot/cache';
-```
-
-### New Simplified API
-```typescript
-// Use factory functions with options only
-const cache = createCache({ keyPrefix: 'app:', ttl: 3600 });
-const tradingCache = createTradingCache();
-const marketCache = createMarketDataCache();
-
-// Only Redis cache is available
-import { RedisCache, RedisConnectionManager } from '@stock-bot/cache';
-```
-
-## Quick Migration Steps
-
-1. **Remove cache type parameters**: Change `createCache('hybrid')` to `createCache()`
-2. **Remove name parameter**: The `name` option is no longer needed  
-3. **Update imports**: Use named imports instead of default import
-4. **Use specialized factories**: Consider using `createTradingCache()`, `createMarketDataCache()`, etc.
-
-For complete usage examples and best practices, see [simplified-cache-usage.md](./simplified-cache-usage.md).

-# Enhanced Cache Provider Usage
-
-The Redis cache provider now supports advanced TTL handling and conditional operations.
-
-## Basic Usage (Backward Compatible)
-
-```typescript
-import { RedisCache } from '@stock-bot/cache';
-
-const cache = new RedisCache({
-  keyPrefix: 'trading:',
-  defaultTTL: 3600 // 1 hour
-});
-
-// Simple set with TTL (old way - still works)
-await cache.set('user:123', userData, 1800); // 30 minutes
-
-// Simple get
-const user = await cache.get<UserData>('user:123');
-```
-
-## Enhanced Set Options
-
-```typescript
-// Preserve existing TTL when updating
-await cache.set('user:123', updatedUserData, { preserveTTL: true });
-
-// Only set if key exists (update operation)
-const oldValue = await cache.set('user:123', newData, { 
-  onlyIfExists: true, 
-  getOldValue: true 
-});
-
-// Only set if key doesn't exist (create operation)
-await cache.set('user:456', newUser, { 
-  onlyIfNotExists: true,
-  ttl: 7200 // 2 hours
-});
-
-// Get old value when setting new one
-const previousData = await cache.set('session:abc', sessionData, { 
-  getOldValue: true,
-  ttl: 1800
-});
-```
-
-## Convenience Methods
-
-```typescript
-// Update value preserving TTL
-await cache.update('user:123', updatedUserData);
-
-// Set only if exists
-const updated = await cache.setIfExists('user:123', newData, 3600);
-
-// Set only if not exists (returns true if created)
-const created = await cache.setIfNotExists('user:456', userData);
-
-// Replace existing key with new TTL
-const oldData = await cache.replace('user:123', newData, 7200);
-
-// Atomic field updates
-await cache.updateField('counter:views', (current) => (current || 0) + 1);
-
-await cache.updateField('user:123', (user) => ({
-  ...user,
-  lastSeen: new Date().toISOString(),
-  loginCount: (user?.loginCount || 0) + 1
-}));
-```
-
-## Stock Bot Use Cases
-
-### 1. Rate Limiting
-```typescript
-// Only create rate limit if not exists
-const rateLimited = await cache.setIfNotExists(
-  `ratelimit:${userId}:${endpoint}`, 
-  { count: 1, resetTime: Date.now() + 60000 },
-  60 // 1 minute
-);
-
-if (!rateLimited) {
-  // Increment existing counter
-  await cache.updateField(`ratelimit:${userId}:${endpoint}`, (data) => ({
-    ...data,
-    count: data.count + 1
-  }));
-}
-```
-
-### 2. Session Management
-```typescript
-// Update session data without changing expiration
-await cache.update(`session:${sessionId}`, {
-  ...sessionData,
-  lastActivity: Date.now()
-});
-```
-
-### 3. Cache Warming
-```typescript
-// Only update existing cached data, don't create new entries
-const warmed = await cache.setIfExists(`stock:${symbol}:price`, latestPrice);
-if (warmed) {
-  console.log(`Warmed cache for ${symbol}`);
-}
-```
-
-### 4. Atomic Counters
-```typescript
-// Thread-safe counter increments
-await cache.updateField('metrics:api:calls', (count) => (count || 0) + 1);
-await cache.updateField('metrics:errors:500', (count) => (count || 0) + 1);
-```
-
-### 5. TTL Preservation for Frequently Updated Data
-```typescript
-// Keep original expiration when updating frequently changing data
-await cache.set(`portfolio:${userId}:positions`, positions, { preserveTTL: true });
-```
-
-## Error Handling
-
-The cache provider includes robust error handling:
-
-```typescript
-try {
-  await cache.set('key', value);
-} catch (error) {
-  // Errors are logged and fallback values returned
-  // The cache operations are non-blocking
-}
-
-// Check cache health
-const isHealthy = await cache.health();
-
-// Wait for cache to be ready
-await cache.waitForReady(10000); // 10 second timeout
-```
-
-## Performance Benefits
-
-1. **Atomic Operations**: `updateField` uses Lua scripts to prevent race conditions
-2. **TTL Preservation**: Avoids unnecessary TTL resets on updates
-3. **Conditional Operations**: Reduces network round trips
-4. **Shared Connections**: Efficient connection pooling
-5. **Error Recovery**: Graceful degradation when Redis is unavailable

+Based on my experience and research, here's a comprehensive breakdown of **strategy development components and where you should focus**:
+
+## The Complete Strategy Development Pipeline
+
+### 1. **Idea Generation & Hypothesis Formation** (15% of effort)
+**What it involves:**
+- Market microstructure understanding
+- Economic rationale for the edge
+- Literature review and academic research
+- Observing market inefficiencies
+
+**Focus Level: MEDIUM**
+- Don't over-research; many good ideas are simple
+- Ensure there's a logical reason WHY the strategy should work
+- Avoid pure data mining without economic rationale
+
+### 2. **Data Infrastructure** (25% of effort)
+**Critical Components:**
+- Data quality and cleaning
+- Survivorship bias handling
+- Corporate actions adjustment
+- Proper point-in-time data
+
+**Focus Level: VERY HIGH** ⭐
+- **This is where most strategies fail in production**
+- Bad data = invalid backtests = losing money
+- Look-ahead bias is the silent killer
+- The time-series nature of financial datasets limits the effective amount of data available to train, validate and retrain models since special care must be taken not to include future data in any way
+
+### 3. **Feature Engineering** (20% of effort)
+**Key Areas:**
+- Market microstructure features (order flow, volume profiles)
+- Cross-sectional features (relative value metrics)
+- Alternative data integration
+- Regime indicators
+
+**Focus Level: HIGH**
+- Features matter more than models
+- Domain expertise pays off here
+- Keep features interpretable when possible
+
+### 4. **Strategy Logic & Signal Generation** (15% of effort)
+**Components:**
+- Entry/exit rules
+- Position sizing algorithms
+- Risk limits and constraints
+- Portfolio construction
+
+**Focus Level: MEDIUM**
+- Simpler is often better
+- Complexity should come from combining simple, robust signals
+- Avoid overfitting with too many rules
+
+### 5. **Backtesting Framework** (10% of effort)
+**Essential Elements:**
+- Transaction cost modeling
+- Market impact estimation
+- Proper execution assumptions
+- Realistic capacity constraints
+
+**Focus Level: HIGH** ⭐
+- Most backtests are too optimistic
+- Walk forward analysis only tests a single price path whereas other tests such as Noise testing, Vs Shifted, Variance testing or Monte Carlo Permutation test multiple price paths
+- Focus on realistic execution assumptions
+
+### 6. **Statistical Validation** (10% of effort)
+**Including:**
+- Permutation tests (as discussed)
+- Out-of-sample testing
+- Statistical significance tests
+- Robustness checks
+
+**Focus Level: MEDIUM-HIGH**
+- Important but don't over-optimize
+- Testing for overfitting at the earliest possible stage
+
+### 7. **Risk Management** (5% of effort but 90% of survival)
+**Critical Aspects:**
+- Drawdown controls
+- Correlation management
+- Tail risk hedging
+- Position limits
+
+**Focus Level: VERY HIGH** ⭐
+- **This determines survival**
+- Good risk management saves bad strategies
+- Bad risk management kills good strategies
+
+## Where You Should REALLY Focus
+
+### 🎯 **Priority 1: Data Quality & Infrastructure**
+**Why:** 
+- 80% of production failures come from data issues
+- It's unsexy but absolutely critical
+- Garbage in = garbage out
+
+**Specific Actions:**
+- Build robust data pipelines
+- Implement comprehensive data quality checks
+- Create point-in-time data snapshots
+- Test for survivorship bias
+
+### 🎯 **Priority 2: Transaction Costs & Market Impact**
+**Why:**
+- The difference between paper and real trading
+- Can turn profitable strategies unprofitable
+- Often underestimated in backtests
+
+**Key Considerations:**
+- Bid-ask spreads during your trading times
+- Market impact models for your size
+- Slippage estimates based on real execution data
+- Hidden costs (borrow costs for shorts, etc.)
+
+### 🎯 **Priority 3: Regime Awareness**
+**Why:**
+- Markets change; strategies that don't adapt die
+- Market dynamics can change, but there is no solution to this risk
+
+**Implementation:**
+- Build regime detection systems
+- Adjust position sizing by regime
+- Have strategy on/off switches
+- Monitor strategy degradation metrics
+
+## Common Traps to Avoid
+
+### 1. **Over-Optimization**
+- Too many parameters = overfitting
+- It is highly recommended for your strategy to have as little configurable parameters (degrees of freedom) as possible
+
+### 2. **Selection Bias**
+- Testing 1000 strategies and picking the best
+- Not accounting for multiple testing
+- One of the permutation tests created by the author detected a hidden selection bias problem in a trading system
+
+### 3. **Ignoring Capacity**
+- Strategy works with $100k but not $10M
+- Market impact kills returns at scale
+- Liquidity constraints binding
+
+### 4. **Complexity Bias**
+- Complex != better
+- Simple strategies are more robust
+- Many strategies that look profitable actually perform just as well on completely random data
+
+## Modern Best Practices (2025)
+
+### 1. **Machine Learning Integration**
+- Use ML for feature selection, not just prediction
+- Ensemble methods for robustness
+- Deep generative models to produce synthetic time-series data, enhancing the amount of data available for training
+
+### 2. **Real-Time Monitoring**
+- Live performance tracking vs. backtest
+- Automatic strategy shutdown triggers
+- A/B testing framework for improvements
+
+### 3. **Alternative Data**
+- Sentiment analysis
+- Satellite data
+- Web scraping (where legal)
+- But validate the alpha decay
+
+### 4. **Execution Alpha**
+- Smart order routing
+- Optimal execution algorithms
+- Dark pool access
+- This is often easier edge than signal alpha
+
+## Recommended Development Process
+
+### Phase 1: Research (2-4 weeks)
+1. Hypothesis formation with economic rationale
+2. Initial data exploration
+3. Simple prototype testing
+4. **Go/No-go decision**
+
+### Phase 2: Development (4-8 weeks)
+1. Full data pipeline build
+2. Feature engineering
+3. Strategy implementation
+4. Initial backtesting
+
+### Phase 3: Validation (2-4 weeks)
+1. Permutation tests
+2. Out-of-sample testing
+3. Sensitivity analysis
+4. **Go/No-go decision**
+
+### Phase 4: Production Prep (2-4 weeks)
+1. Execution infrastructure
+2. Risk management systems
+3. Monitoring and alerting
+4. Paper trading
+
+### Phase 5: Go-Live (Ongoing)
+1. Gradual position scaling
+2. Live performance monitoring
+3. Continuous improvement
+4. Regular strategy review
+
+## The Reality Check
+
+**What Actually Matters Most:**
+1. **Data quality** (can't emphasize enough)
+2. **Transaction costs** (the silent killer)
+3. **Risk management** (determines survival)
+4. **Execution quality** (often overlooked)
+5. **Regime adaptability** (markets change)
+
+**What's Often Overemphasized:**
+1. Complex models (simple often better)
+2. Perfect optimization (robustness > perfection)
+3. High Sharpe ratios in backtest (usually unrealistic)
+4. Academic purity (markets are messy)
+
+## Final Advice
+
+Focus on building **robust, simple strategies** with:
+- Clean data pipelines
+- Realistic execution assumptions  
+- Strong risk management
+- Adaptability to changing markets
+
+Remember: Over 90% of strategies that look amazing fail in production. The difference between success and failure is usually in the unglamorous details of data quality, execution, and risk management, not in having the most sophisticated model.
+
+Start simple, test thoroughly, and scale gradually. The market will teach you humility quickly enough.

-# Loki Logging for Stock Bot
-
-This document outlines how to use the Loki logging system integrated with the Stock Bot platform (Updated June 2025).
-
-## Overview
-
-Loki provides centralized logging for all Stock Bot services with:
-
-1. **Centralized logging** for all microservices
-2. **Log aggregation** and filtering by service, level, and custom labels
-3. **Grafana integration** for visualization and dashboards
-4. **Query capabilities** using LogQL for log analysis
-5. **Alert capabilities** for critical issues
-
-## Getting Started
-
-### Starting the Logging Stack
-
-```cmd
-# Start the monitoring stack (includes Loki and Grafana)
-scripts\docker.ps1 monitoring
-```
-
-Or start services individually:
-
-```cmd
-# Start Loki service only
-docker-compose up -d loki
-
-# Start Loki and Grafana
-docker-compose up -d loki grafana
-```
-
-### Viewing Logs
-
-Once started:
-
-1. Access Grafana at http://localhost:3000 (login with admin/admin)
-2. Navigate to the "Stock Bot Logs" dashboard
-3. View and query your logs
-
-## Using the Logger in Your Services
-
-The Stock Bot logger automatically sends logs to Loki using the updated pattern:
-
-```typescript
-import { getLogger } from '@stock-bot/logger';
-
-// Create a logger for your service
-const logger = getLogger('your-service-name');
-
-// Log at different levels
-logger.debug('Detailed information for debugging');
-logger.info('General information about operations');
-logger.warn('Potential issues that don\'t affect operation');
-logger.error('Critical errors that require attention');
-
-// Log with structured data (searchable in Loki)
-logger.info('Processing trade', { 
-  symbol: 'MSFT', 
-  price: 410.75, 
-  quantity: 50 
-});
-```
-
-## Configuration Options
-
-Logger configuration is managed through the `@stock-bot/config` package and can be set in your `.env` file:
-
-```bash
-# Logging configuration
-LOG_LEVEL=debug           # debug, info, warn, error
-LOG_CONSOLE=true          # Log to console in addition to Loki
-LOKI_HOST=localhost       # Loki server hostname
-LOKI_PORT=3100            # Loki server port
-LOKI_RETENTION_DAYS=30    # Days to retain logs
-LOKI_LABELS=environment=development,service=stock-bot  # Default labels
-LOKI_BATCH_SIZE=100       # Number of logs to batch before sending
-LOKI_BATCH_WAIT=5         # Max time to wait before sending logs
-```
-
-## Useful Loki Queries
-
-Inside Grafana, you can use these LogQL queries to analyze your logs:
-
-1. **All logs from a specific service**:
-   ```
-   {service="market-data-gateway"}
-   ```
-
-2. **All error logs across all services**:
-   ```
-   {level="error"}
-   ```
-
-3. **Logs containing specific text**:
-   ```
-   {service="market-data-gateway"} |= "trade"
-   ```
-
-4. **Count of error logs by service over time**:
-   ```
-   sum by(service) (count_over_time({level="error"}[5m]))
-   ```
-
-## Testing the Logging Integration
-
-Test the logging integration using Bun:
-
-```cmd
-# Run from project root using Bun (current runtime)
-bun run tools/test-loki-logging.ts
-```
-
-## Architecture
-
-Our logging implementation follows this architecture:
-
-```
-┌─────────────────┐     ┌─────────────────┐
-│ Trading Services│────►│ @stock-bot/logger│
-└─────────────────┘     │   getLogger()   │
-                        └────────┬────────┘
-                                 │
-                                 ▼
-┌────────────────────────────────────────┐
-│               Loki                     │
-└────────────────┬───────────────────────┘
-                 │
-                 ▼
-┌────────────────────────────────────────┐
-│              Grafana                   │
-└────────────────────────────────────────┘
-```
-
-## Adding New Dashboards
-
-To create new Grafana dashboards for log visualization:
-
-1. Build your dashboard in the Grafana UI
-2. Export it to JSON
-3. Add it to `monitoring/grafana/provisioning/dashboards/json/`
-4. Restart the monitoring stack
-
-## Troubleshooting
-
-If logs aren't appearing in Grafana:
-
-1. Run the status check script to verify Loki and Grafana are working:
-   ```cmd
-   tools\check-loki-status.bat
-   ```
-
-2. Check that Loki and Grafana containers are running:
-   ```cmd
-   docker ps | findstr "loki grafana"
-   ```
-
-3. Verify .env configuration for Loki host and port:
-   ```cmd
-   type .env | findstr "LOKI_"
-   ```
-
-4. Ensure your service has the latest @stock-bot/logger package
-
-5. Check for errors in the Loki container logs:
-   ```cmd
-   docker logs stock-bot-loki
-   ```

+### **📊 Data Flow**
+
+```
+1. INGESTION: Providers → 12900K MongoDB/Pipeline
+2. PROCESSING: Raw → Features → 12900K QuestDB
+3. HOT SYNC: Last 90 days → 9900K QuestDB

+5. ARCHIVE: Old data → TrueNAS MinIO (Parquet)
+```
+
+### **🔑 Key Design Decisions**
+
+```python
+architecture_principles = {
+    "Isolation": "Live/Paper completely separated",
+    "Performance": "Hot data on NVMe, cold on HDD",
+    "Scalability": "200K symbols, 40+ years data",
+    "Processing": "Dask over Spark (Python native)",
+    "Safety": "Live trading NEVER competes for resources"
+}
+```
+
+### **💾 Database Strategy**
+
+| Database | Location | Purpose | Size |
+|----------|----------|---------|------|
+| QuestDB | 9900K | Hot OHLC/Ticks | ~200GB |
+| Redis | 9900K | Live State | ~2GB |
+| PostgreSQL | 12900K | Metadata/Config | ~100GB |
+| MongoDB | 12900K | Raw Data (8GB cache) | ~500GB |
+| QuestDB | 12900K | Historical | ~500GB |
+| MinIO | TrueNAS | Archives | ~TBs |
+
+### **🚀 Performance Optimizations**
+
+```yaml
+Completed:
+✓ MongoDB cache limited to 8GB
+✓ CPU affinity for live/paper trading
+✓ Network architecture planned
+✓ Database separation by access pattern
+✓ Ubuntu 24.04 LTS chosen
+
+Next Steps:
+- Set up Dask cluster on 12900K
+- Implement data sync pipeline
+- Configure monitoring stack
+- Test 20-year backtest performance
+```
+
+### **📈 Capacity**
+
+```
+- Symbols: 200,000 total (10-20K active)
+- History: 40+ years
+- Storage: 32TB available
+- Backtest: 20 years feasible in ~2 days
+- Live latency: <1ms target
+```
+
+Your infrastructure is well-designed for institutional-grade algo trading with proper separation of concerns and room to scale! The MongoDB fix freed up significant resources for actual trading/analysis work.

-# Simplified Cache Library Usage
-
-The cache library has been simplified to only use Redis/Dragonfly with a connection manager for better performance and easier management.
-
-## Quick Start
-
-```typescript
-import { createCache, createTradingCache, createMarketDataCache, RedisConnectionManager } from '@stock-bot/cache';
-
-// Create different cache instances
-const generalCache = createCache({ keyPrefix: 'app:' });
-const tradingCache = createTradingCache(); // Uses 'trading:' prefix
-const marketCache = createMarketDataCache(); // Uses 'market:' prefix with 5min TTL
-
-// All cache instances share connections by default for better performance
-```
-
-## Connection Management
-
-The library now uses a connection manager that allows you to control whether services share connections or get unique ones:
-
-```typescript
-import { RedisConnectionManager } from '@stock-bot/cache';
-
-const connectionManager = RedisConnectionManager.getInstance();
-
-// For shared connections (recommended for most cases)
-const sharedRedis = connectionManager.getConnection({
-  name: 'BATCH-PROCESSOR',
-  singleton: true  // All instances share this connection
-});
-
-// For unique connections (when you need isolation)
-const uniqueRedis = connectionManager.getConnection({
-  name: 'DATA-FETCHER',
-  singleton: false  // Each instance gets its own connection
-});
-```
-
-## Cache Usage Examples
-
-### Basic Operations
-
-```typescript
-import { createCache } from '@stock-bot/cache';
-
-const cache = createCache({ keyPrefix: 'myapp:' });
-
-// Set data with default TTL (1 hour)
-await cache.set('user:123', { name: 'John', email: 'john@example.com' });
-
-// Set data with custom TTL (5 minutes)
-await cache.set('session:abc', sessionData, 300);
-
-// Get data
-const user = await cache.get('user:123');
-
-// Check if key exists
-const exists = await cache.exists('user:123');
-
-// Delete data
-await cache.del('user:123');
-
-// Clear all data with this prefix
-await cache.clear();
-```
-
-### Trading-Specific Caches
-
-```typescript
-import { createTradingCache, createMarketDataCache, createIndicatorCache } from '@stock-bot/cache';
-
-// Trading cache (1 hour TTL)
-const tradingCache = createTradingCache();
-await tradingCache.set('position:AAPL', { shares: 100, price: 150.00 });
-
-// Market data cache (5 minute TTL)
-const marketCache = createMarketDataCache();
-await marketCache.set('quote:AAPL', { price: 151.25, volume: 1000000 });
-
-// Indicator cache (30 minute TTL)
-const indicatorCache = createIndicatorCache();
-await indicatorCache.set('sma:AAPL:20', [150.1, 150.3, 150.8, 151.2]);
-```
-
-## Connection Names in Redis
-
-When you create cache instances, they will appear in Redis with clean, identifiable names:
-
-- `TRADING-SERVICE` - For trading cache
-- `MARKET-SERVICE` - For market data cache  
-- `INDICATORS-SERVICE` - For indicator cache
-- `CACHE-SERVICE` - For general cache
-
-You can monitor all connections using:
-
-```bash
-# TypeScript version (more detailed)
-bun run scripts/get-redis-connections.ts
-
-# Bash version (quick check)
-./scripts/get-redis-connections.sh
-```
-
-## Health Monitoring
-
-```typescript
-// Check if cache is ready
-if (cache.isReady()) {
-  console.log('Cache is ready for operations');
-}
-
-// Wait for cache to be ready
-await cache.waitForReady(5000); // Wait up to 5 seconds
-
-// Health check
-const isHealthy = await cache.health();
-
-// Get performance statistics
-const stats = cache.getStats();
-console.log(`Hit rate: ${stats.hitRate}%, Total operations: ${stats.total}`);
-```
-
-## Batch Processor Example
-
-Here's how to set up a batch processor with a shared connection:
-
-```typescript
-import { RedisConnectionManager } from '@stock-bot/cache';
-import Redis from 'ioredis';
-
-export class BatchProcessor {
-  private redis: Redis;
-
-  constructor() {
-    const connectionManager = RedisConnectionManager.getInstance();
-    
-    // All batch processor instances share this connection
-    this.redis = connectionManager.getConnection({
-      name: 'BATCH-PROCESSOR',
-      singleton: true
-    });
-  }
-
-  async processItems(items: any[]): Promise<void> {
-    await this.redis.set('batch:status', 'processing');
-    
-    for (const item of items) {
-      await this.redis.lpush('batch:queue', JSON.stringify(item));
-    }
-    
-    await this.redis.set('batch:status', 'completed');
-  }
-
-  async getBatchStatus(): Promise<string> {
-    return await this.redis.get('batch:status') || 'idle';
-  }
-}
-```
-
-## Key Benefits
-
-✅ **Simplified**: Only Redis-based caching, no complex hybrid logic  
-✅ **Connection Management**: Shared connections for better performance  
-✅ **Clean Monitoring**: Easy to identify connections in Redis  
-✅ **Trading Optimized**: Pre-configured caches for different data types  
-✅ **Type Safe**: Full TypeScript support  
-✅ **Error Handling**: Graceful fallbacks and comprehensive logging  
-
-## Removed Features
-
-❌ **Memory Cache**: Removed to avoid consistency issues  
-❌ **Hybrid Cache**: Removed unnecessary complexity  
-❌ **Auto-detection**: Always uses Redis/Dragonfly now  
-
-This simplified approach provides better performance, easier debugging, and more predictable behavior for your trading application.

-# Testing with Bun in Stock Bot Platform
-
-The Stock Bot platform uses [Bun Test](https://bun.sh/docs/cli/test) as the primary testing framework (Updated June 2025). Bun Test provides fast, modern testing with Jest-like API compatibility.
-
-## Getting Started
-
-Run tests using these commands:
-
-```cmd
-# Run all tests (using Turbo)
-bun test
-
-# Run tests in watch mode
-bun test:watch
-
-# Run tests with coverage
-bun test:coverage
-
-# Run specific test types
-bun test:unit
-bun test:integration
-bun test:e2e
-```
-
-## Library-specific Testing
-
-Each library has its own testing configuration in a `bunfig.toml` file. This allows for library-specific test settings while maintaining consistent patterns across the codebase.
-
-### Example bunfig.toml:
-
-```toml
-[test]
-preload = ["./test/setup.ts"]
-timeout = 5000
-
-[test.env]
-NODE_ENV = "test"
-
-[bun]
-paths = {
-  "@/*" = ["./src/*"]
-}
-```
-
-## Migration from Jest
-
-This project has been fully migrated from Jest to Bun Test. Some key differences:
-
-1. **Import statements**: Use `import { describe, it, expect } from 'bun:test'` instead of Jest imports
-2. **Mocking**: Use Bun's built-in mocking utilities (see global `spyOn` helper)
-3. **Configuration**: Use `bunfig.toml` instead of Jest config files
-4. **Test helpers**: Test helpers are available globally via `global.testHelpers`
-
-## Best Practices
-
-- Use `describe` and `it` for test organization
-- Use relative imports (`../src/`) in test files
-- Keep test setup clean with proper `beforeEach` and `afterEach` handlers
-- For complex test scenarios, create dedicated setup files
-
-## Test Environment
-
-- All tests run with `NODE_ENV=test`
-- Console output is silenced by default (restore with `testHelpers.restoreConsole()`)
-- Default timeout is 30 seconds for integration tests, 5 seconds for unit tests

-# TypeScript Configuration Structure
-
-This document explains the TypeScript configuration structure used in the Stock Bot trading platform.
-
-## Root Configuration
-
-The root `tsconfig.json` at the project root establishes common settings for all projects in the monorepo:
-
-```json
-{
-  "$schema": "https://json.schemastore.org/tsconfig",
-  "compilerOptions": {
-    "target": "ES2022",
-    "module": "NodeNext",
-    "moduleResolution": "NodeNext",
-    "strict": true,
-    "noImplicitAny": true,
-    "strictNullChecks": true,
-    "noImplicitThis": true,
-    "alwaysStrict": true,
-    "esModuleInterop": true,
-    "allowSyntheticDefaultImports": true,
-    "skipLibCheck": true,
-    "forceConsistentCasingInFileNames": true,
-    "resolveJsonModule": true,
-    "sourceMap": false,
-    "declaration": true,
-    "baseUrl": ".",
-    "paths": {
-      "@stock-bot/*": ["libs/*/src"]
-    }
-  },
-  "exclude": [
-    "node_modules",
-    "dist"
-  ]
-}
-```
-
-## Template Configurations
-
-We provide two template configurations:
-
-1. `tsconfig.lib.json` - For library projects:
-```json
-{
-  "extends": "../../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "./dist",
-    "rootDir": "./src",
-    "declaration": true
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist", "**/*.test.ts", "**/*.spec.ts"]
-}
-```
-
-2. `tsconfig.app.json` - For application projects:
-```json
-{
-  "extends": "../../../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "./dist",
-    "rootDir": "./src",
-    "module": "ESNext",
-    "moduleResolution": "bundler",
-    "types": ["bun-types"]
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist"]
-}
-```
-
-## Project-Specific Configurations
-
-Each project in the monorepo extends from the root configuration and adds its own specific settings:
-
-### Library Projects
-
-Library projects extend the root configuration with a relative path:
-```json
-{
-  "extends": "../../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "./dist",
-    "rootDir": "./src",
-    "declaration": true
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist", "**/*.test.ts", "**/*.spec.ts"]
-}
-```
-
-### Application Projects
-
-Application projects also extend the root configuration with a relative path:
-```json
-{
-  "extends": "../../../tsconfig.json",
-  "compilerOptions": {
-    "outDir": "./dist",
-    "rootDir": "./src",
-    "module": "ESNext",
-    "moduleResolution": "bundler",
-    "types": ["bun-types"]
-  },
-  "include": ["src/**/*"],
-  "exclude": ["node_modules", "dist"]
-}
-```
-
-## Special Configurations
-
-Some projects have special needs:
-
-1. **Trading Dashboard (Angular)**: Uses an extended configuration structure with separate files for app and testing.
-
-2. **Projects with TypeScript imports from extensions**: These projects set `"allowImportingTsExtensions": true` and `"noEmit": true`.

+# Library Standards and Patterns
+
+This document defines the standardized patterns for all libraries in the @stock-bot ecosystem.
+
+## Export Patterns
+
+### Standard: Named Exports Only
+
+All libraries should use **named exports only**. Default exports have been removed for consistency and better tree-shaking.
+
+**Example:**
+```typescript
+// ✅ Good - Named exports
+export { createCache } from './cache';
+export type { CacheOptions } from './types';
+
+// ❌ Bad - Default export
+export default createCache;
+```
+
+## Initialization Patterns
+
+Libraries follow different initialization patterns based on their purpose:
+
+### 1. Singleton with Global State
+**Use for:** Global services that should have only one instance (config, logger)
+
+**Example:** Config library
+```typescript
+let configInstance: ConfigManager | null = null;
+
+export function initializeConfig(): AppConfig {
+  if (!configInstance) {
+    configInstance = new ConfigManager();
+  }
+  return configInstance.initialize();
+}
+
+export function getConfig(): AppConfig {
+  if (!configInstance) {
+    throw new Error('Config not initialized');
+  }
+  return configInstance.get();
+}
+```
+
+### 2. Factory with Registry
+**Use for:** Services that need instance reuse based on configuration (cache, logger instances)
+
+**Example:** Cache library
+```typescript
+const cacheInstances = new Map<string, CacheProvider>();
+
+export function createCache(options: CacheOptions): CacheProvider {
+  if (options.shared) {
+    const key = generateKey(options);
+    if (cacheInstances.has(key)) {
+      return cacheInstances.get(key)!;
+    }
+    const cache = new RedisCache(options);
+    cacheInstances.set(key, cache);
+    return cache;
+  }
+  return new RedisCache(options);
+}
+```
+
+### 3. Pure Factory Functions
+**Use for:** Services that need creation logic beyond simple instantiation
+
+**Example:** Event bus with configuration processing
+```typescript
+export function createEventBus(config: EventBusConfig): EventBus {
+  // Process config, set defaults, etc.
+  const processedConfig = { ...defaultConfig, ...config };
+  return new EventBus(processedConfig);
+}
+```
+
+**Note:** Simple instantiation doesn't need factories - use direct class instantiation or DI container.
+
+### 4. Direct Class Exports
+**Use for:** Simple utilities or services managed by DI container
+
+**Example:** MongoDB library
+```typescript
+export { MongoDBClient } from './client';
+// No factory function - let DI container handle instantiation
+```
+
+### 5. Singleton Classes
+**Use for:** Manager classes that coordinate multiple instances
+
+**Example:** QueueManager
+```typescript
+export class QueueManager {
+  private static instance: QueueManager | null = null;
+  
+  static initialize(config: QueueConfig): QueueManager {
+    if (!QueueManager.instance) {
+      QueueManager.instance = new QueueManager(config);
+    }
+    return QueueManager.instance;
+  }
+  
+  static getInstance(): QueueManager {
+    if (!QueueManager.instance) {
+      throw new Error('QueueManager not initialized');
+    }
+    return QueueManager.instance;
+  }
+}
+```
+
+## Pattern Selection Guide
+
+Choose the initialization pattern based on these criteria:
+
+| Pattern | When to Use | Examples |
+|---------|-------------|----------|
+| **Singleton with Global State** | - One instance per process<br>- Stateful configuration<br>- Process-wide settings | config, logger setup |
+| **Factory with Registry** | - Multiple instances with same config should share<br>- Connection pooling<br>- Resource optimization | cache, logger instances |
+| **Pure Factory** | - Complex initialization logic<br>- Configuration processing needed<br>- Defaults to apply | event bus (if needed) |
+| **Direct Class Export** | - DI container manages lifecycle<br>- Simple initialization<br>- No special setup needed | database clients (MongoDB, PostgreSQL, QuestDB), utilities |
+| **Singleton Class** | - Coordinates multiple resources<br>- Central management point<br>- Graceful shutdown needed | QueueManager, ConnectionManager |
+
+## Additional Standards
+
+### Error Handling
+- All libraries should throw descriptive errors
+- Consider creating custom error classes for domain-specific errors
+- Always include context in error messages
+
+### Configuration
+- Accept configuration through constructor/factory parameters
+- Validate configuration using Zod schemas
+- Provide sensible defaults where appropriate
+
+### Testing
+- All libraries must have unit tests
+- Use consistent test file naming: `*.test.ts`
+- Mock external dependencies
+
+### Documentation
+- Every library must have a README.md
+- Include usage examples
+- Document all public APIs with JSDoc
+
+### TypeScript
+- Export all public types
+- Use strict TypeScript settings
+- Avoid `any` types
+
+### Dependencies
+- Minimize external dependencies
+- Use exact versions for critical dependencies
+- Document peer dependencies clearly

-# @stock-bot/config
-
-A configuration management library for the Stock Bot trading platform.
-
-## Overview
-
-This library provides a centralized way to manage configurations across all Stock Bot microservices and components. It includes:
-
-- Environment-based configuration loading
-- Strong TypeScript typing and validation using Zod
-- Default configurations for services
-- Environment variable parsing helpers
-- Service-specific configuration modules
-
-## Usage
-
-### Basic Usage
-
-```typescript
-import { databaseConfig, dataProviderConfigs, riskConfig } from '@stock-bot/config';
-
-// Access database configuration
-const dragonflyHost = databaseConfig.dragonfly.host;
-
-// Access data provider configuration
-const alpacaApiKey = dataProviderConfigs.providers.find(p => p.name === 'alpaca')?.apiKey;
-
-// Access risk configuration
-const maxPositionSize = riskConfig.maxPositionSize;
-```
-
-### Service-Specific Configuration
-
-```typescript
-import { marketDataGatewayConfig, riskGuardianConfig } from '@stock-bot/config';
-
-// Access Market Data Gateway configuration
-const websocketPath = marketDataGatewayConfig.websocket.path;
-
-// Access Risk Guardian configuration
-const preTradeValidation = riskGuardianConfig.riskChecks.preTradeValidation;
-```
-
-### Environment Variables
-
-The library automatically loads environment variables from `.env` files. You can create environment-specific files:
-
-- `.env` - Base environment variables 
-- `.env.development` - Development-specific variables
-- `.env.production` - Production-specific variables
-- `.env.local` - Local overrides (not to be committed to git)
-
-## Configuration Modules
-
-### Core Configuration
-
-- `Environment` - Enum for different environments
-- `loadEnvVariables()` - Load environment variables from .env files
-- `getEnvironment()` - Get the current environment
-- `validateConfig()` - Validate configuration with Zod schema
-
-### Database Configuration
-
-- `databaseConfig` - Database connection settings (Dragonfly, QuestDB, MongoDB, PostgreSQL)
-
-### Data Provider Configuration
-
-- `dataProviderConfigs` - Settings for market data providers
-
-### Risk Configuration
-
-- `riskConfig` - Risk management parameters (max drawdown, position size, etc.)
-
-### Service-Specific Configuration
-
-- `marketDataGatewayConfig` - Configs for the Market Data Gateway service
-- `riskGuardianConfig` - Configs for the Risk Guardian service
-
-## Extending
-
-To add a new service configuration:
-
-1. Create a new file in `src/services/`
-2. Define a Zod schema for validation
-3. Create loading and default configuration functions
-4. Export from `src/services/index.ts`
-5. The new configuration will be automatically available from the main package
-
-## Development
-
-```bash
-# Install dependencies
-bun install
-
-# Run tests
-bun test
-
-# Type check
-bun run type-check
-
-# Lint
-bun run lint
-```

-# Stock Bot Configuration Library Usage Guide
-
-This guide shows how to use the Zod-based configuration system in the Stock Bot platform.
-
-## Quick Start
-
-```typescript
-import { databaseConfig, loggingConfig, riskConfig, dataProvidersConfig } from '@stock-bot/config';
-
-// Access individual values
-console.log(`Database: ${databaseConfig.POSTGRES_HOST}:${databaseConfig.POSTGRES_PORT}`);
-console.log(`Log level: ${loggingConfig.LOG_LEVEL}`);
-console.log(`Max position size: ${riskConfig.RISK_MAX_POSITION_SIZE}`);
-```
-
-## Environment Variables
-
-All configuration is driven by environment variables. You can set them in:
-- `.env` files
-- System environment variables
-- Docker environment variables
-
-### Database Configuration
-```bash
-DB_HOST=localhost
-DB_PORT=5432
-DB_NAME=stockbot
-DB_USER=stockbot
-DB_PASSWORD=your_password
-DB_SSL=false
-DB_POOL_MAX=10
-```
-
-### Logging Configuration
-```bash
-LOG_LEVEL=info
-LOG_CONSOLE=true
-LOKI_HOST=localhost
-LOKI_PORT=3100
-LOKI_LABELS=service=market-data-gateway,version=1.0.0
-```
-
-### Risk Management Configuration
-```bash
-RISK_MAX_POSITION_SIZE=0.1
-RISK_DEFAULT_STOP_LOSS=0.05
-RISK_DEFAULT_TAKE_PROFIT=0.15
-RISK_CIRCUIT_BREAKER_ENABLED=true
-```
-
-### Data Provider Configuration
-```bash
-DEFAULT_DATA_PROVIDER=alpaca
-ALPACA_API_KEY=your_api_key
-ALPACA_API_SECRET=your_api_secret
-ALPACA_ENABLED=true
-POLYGON_ENABLED=false
-```
-
-## Advanced Usage
-
-### Type Safety
-All configurations are fully typed:
-
-```typescript
-import type { DatabaseConfig, LoggingConfig, RiskConfig } from '@stock-bot/config';
-
-function setupDatabase(config: DatabaseConfig) {
-  // TypeScript knows all the available properties
-  return {
-    host: config.POSTGRES_HOST,
-    port: config.POSTGRES_PORT, // number
-    ssl: config.POSTGRES_SSL,   // boolean
-  };
-}
-```
-
-### Environment Detection
-```typescript
-import { getEnvironment, Environment } from '@stock-bot/config';
-
-const env = getEnvironment();
-if (env === Environment.Production) {
-  // Production-specific logic
-}
-```
-
-### Data Provider Helpers
-```typescript
-import { getProviderConfig, getEnabledProviders, getDefaultProvider } from '@stock-bot/config';
-
-// Get specific provider
-const alpaca = getProviderConfig('alpaca');
-
-// Get all enabled providers
-const providers = getEnabledProviders();
-
-// Get default provider
-const defaultProvider = getDefaultProvider();
-```
-
-## Configuration Files
-
-The library consists of these modules:
-
-- **core.ts** - Core utilities and environment detection
-- **database.ts** - Database connection settings
-- **logging.ts** - Logging and Loki configuration
-- **risk.ts** - Risk management parameters
-- **data-providers.ts** - Data provider settings
-
-## Benefits of This Approach
-
-1. **Zero Configuration Schema** - No complex schema definitions needed
-2. **Automatic Type Inference** - TypeScript types are generated automatically
-3. **Environment Variable Validation** - Invalid values are caught at startup
-4. **Great Developer Experience** - IntelliSense works perfectly
-5. **Production Ready** - Used by many large-scale applications
-
-## Migration from Previous System
-
-If you're migrating from the old Valibot-based system:
-
-```typescript
-// Old way
-const config = createConfigLoader('database', databaseSchema, defaultConfig)();
-
-// New way
-import { databaseConfig } from '@stock-bot/config';
-// That's it! No schema needed, no validation needed, no complex setup.
-```

+# @stock-bot/config
+
+A robust, type-safe configuration library for the Stock Bot application. Built with Zod for validation and supports multiple configuration sources with proper precedence.
+
+## Features
+
+- **Type-safe configuration** with Zod schemas
+- **Multiple configuration sources**: JSON files and environment variables
+- **Environment-specific overrides** (development, test, production)
+- **Dynamic provider configurations**
+- **No circular dependencies** - designed to be used by all other libraries
+- **Clear error messages** with validation
+- **Runtime configuration updates** (useful for testing)
+- **Singleton pattern** for global configuration access
+
+## Installation
+
+```bash
+bun add @stock-bot/config
+```
+
+## Usage
+
+### Basic Usage
+
+```typescript
+import { initializeConfig, getConfig } from '@stock-bot/config';
+
+// Initialize configuration (call once at app startup)
+await initializeConfig();
+
+// Get configuration
+const config = getConfig();
+console.log(config.database.postgres.host);
+
+// Use convenience functions
+import { getDatabaseConfig, isProduction } from '@stock-bot/config';
+
+const dbConfig = getDatabaseConfig();
+if (isProduction()) {
+  // Production-specific logic
+}
+```
+
+### Custom Configuration
+
+```typescript
+import { ConfigManager } from '@stock-bot/config';
+import { z } from 'zod';
+
+// Define your schema
+const myConfigSchema = z.object({
+  app: z.object({
+    name: z.string(),
+    version: z.string(),
+  }),
+  features: z.object({
+    enableBeta: z.boolean().default(false),
+  }),
+});
+
+// Create config manager
+const configManager = new ConfigManager({
+  configPath: './my-config',
+});
+
+// Initialize with schema
+const config = await configManager.initialize(myConfigSchema);
+```
+
+### Provider-Specific Configuration
+
+```typescript
+import { getProviderConfig } from '@stock-bot/config';
+
+// Get provider configuration
+const eodConfig = getProviderConfig('eod');
+console.log(eodConfig.apiKey);
+
+// Check if provider is enabled
+if (eodConfig.enabled) {
+  // Use EOD provider
+}
+```
+
+### Environment Variables
+
+Environment variables are loaded with the `STOCKBOT_` prefix and follow a naming convention:
+
+```bash
+# Database configuration
+STOCKBOT_DATABASE_POSTGRES_HOST=localhost
+STOCKBOT_DATABASE_POSTGRES_PORT=5432
+
+# Provider configuration
+STOCKBOT_PROVIDERS_EOD_API_KEY=your_api_key
+STOCKBOT_PROVIDERS_EOD_ENABLED=true
+
+# Service configuration
+STOCKBOT_SERVICE_PORT=3000
+STOCKBOT_LOGGING_LEVEL=debug
+```
+
+### Configuration Precedence
+
+Configuration is loaded in the following order (later sources override earlier ones):
+
+1. `config/default.json` - Base configuration
+2. `config/{environment}.json` - Environment-specific overrides
+3. Environment variables - Highest priority
+
+### Advanced Usage
+
+```typescript
+import { getConfigManager } from '@stock-bot/config';
+
+const manager = getConfigManager();
+
+// Get specific value by path
+const port = manager.getValue<number>('service.port');
+
+// Check if configuration exists
+if (manager.has('providers.ib')) {
+  // IB provider is configured
+}
+
+// Update configuration at runtime (useful for testing)
+manager.set({
+  logging: {
+    level: 'debug'
+  }
+});
+
+// Create typed getter
+const getQueueConfig = manager.createTypedGetter(queueConfigSchema);
+const queueConfig = getQueueConfig();
+```
+
+## Configuration Schema
+
+The library provides pre-defined schemas for common configurations:
+
+### Base Configuration
+- `environment` - Current environment (development/test/production)
+- `name` - Application name
+- `version` - Application version
+- `debug` - Debug mode flag
+
+### Service Configuration
+- `name` - Service name
+- `port` - Service port
+- `host` - Service host
+- `healthCheckPath` - Health check endpoint
+- `cors` - CORS configuration
+
+### Database Configuration
+- `postgres` - PostgreSQL configuration
+- `questdb` - QuestDB configuration
+- `mongodb` - MongoDB configuration
+- `dragonfly` - Dragonfly/Redis configuration
+
+### Provider Configuration
+- `eod` - EOD Historical Data provider
+- `ib` - Interactive Brokers provider
+- `qm` - QuoteMedia provider
+- `yahoo` - Yahoo Finance provider
+
+## Testing
+
+```typescript
+import { resetConfig, initializeConfig } from '@stock-bot/config';
+
+beforeEach(() => {
+  resetConfig();
+});
+
+test('custom config', async () => {
+  process.env.NODE_ENV = 'test';
+  process.env.STOCKBOT_SERVICE_PORT = '4000';
+  
+  await initializeConfig();
+  const config = getConfig();
+  
+  expect(config.service.port).toBe(4000);
+});
+```
+
+## Custom Loaders
+
+You can create custom configuration loaders:
+
+```typescript
+import { ConfigLoader } from '@stock-bot/config';
+
+class ApiConfigLoader implements ConfigLoader {
+  readonly priority = 75; // Between file (50) and env (100)
+  
+  async load(): Promise<Record<string, unknown>> {
+    // Fetch configuration from API
+    const response = await fetch('https://api.example.com/config');
+    return response.json();
+  }
+}
+
+// Use custom loader
+const configManager = new ConfigManager({
+  loaders: [
+    new FileLoader('./config', 'production'),
+    new ApiConfigLoader(),
+    new EnvLoader('STOCKBOT_'),
+  ],
+});
+```
+
+## Error Handling
+
+The library provides specific error types:
+
+```typescript
+import { ConfigError, ConfigValidationError } from '@stock-bot/config';
+
+try {
+  await initializeConfig();
+} catch (error) {
+  if (error instanceof ConfigValidationError) {
+    console.error('Validation failed:', error.errors);
+  } else if (error instanceof ConfigError) {
+    console.error('Configuration error:', error.message);
+  }
+}
+```
+
+## Best Practices
+
+1. **Initialize once**: Call `initializeConfig()` once at application startup
+2. **Use schemas**: Always define and validate configurations with Zod schemas
+3. **Environment variables**: Use the `STOCKBOT_` prefix for all env vars
+4. **Type safety**: Leverage TypeScript types from the schemas
+5. **Testing**: Reset configuration between tests with `resetConfig()`

+# DI Container - Modular Structure
+
+## Overview
+
+The DI container has been refactored into a modular structure for better organization and maintainability.
+
+## Directory Structure
+
+```
+├── container/          # Core container logic
+│   ├── builder.ts      # Fluent API for building containers
+│   ├── factory.ts      # Factory functions (legacy compatibility)
+│   └── types.ts        # Type definitions
+├── registrations/      # Service registration modules
+│   ├── core.ts         # Core services (config, logger)
+│   ├── cache.ts        # Cache services
+│   ├── database.ts     # Database clients
+│   └── service.ts      # Application services
+├── config/             # Configuration management
+│   └── schemas/        # Zod schemas for validation
+├── factories/          # Service factories
+│   └── cache.factory.ts # Cache factory utilities
+└── utils/              # Utilities
+    └── lifecycle.ts    # Service lifecycle management
+```
+
+## Usage Examples
+
+### Using the Builder Pattern (Recommended)
+
+```typescript
+import { ServiceContainerBuilder } from '@stock-bot/di';
+
+// Create container with fluent API
+const container = await new ServiceContainerBuilder()
+  .withConfig({
+    redis: { host: 'localhost', port: 6379 },
+    mongodb: { uri: 'mongodb://localhost', database: 'mydb' },
+    postgres: { host: 'localhost', database: 'mydb', user: 'user', password: 'pass' }
+  })
+  .enableService('enableQueue', false) // Disable queue service
+  .enableService('enableBrowser', false) // Disable browser service
+  .build();
+
+// Services are automatically initialized
+const cache = container.cradle.cache;
+const mongoClient = container.cradle.mongoClient;
+```
+
+### Creating Namespaced Caches
+
+```typescript
+import { CacheFactory } from '@stock-bot/di';
+
+// Create a cache for a specific service
+const serviceCache = CacheFactory.createCacheForService(container, 'myservice');
+
+// Create a cache for a handler
+const handlerCache = CacheFactory.createCacheForHandler(container, 'myhandler');
+
+// Create a cache with custom prefix
+const customCache = CacheFactory.createCacheWithPrefix(container, 'custom');
+```
+
+### Manual Service Lifecycle
+
+```typescript
+import { ServiceContainerBuilder, ServiceLifecycleManager } from '@stock-bot/di';
+
+// Create container without auto-initialization
+const container = await new ServiceContainerBuilder()
+  .withConfig(config)
+  .skipInitialization()
+  .build();
+
+// Manually initialize services
+const lifecycle = new ServiceLifecycleManager();
+await lifecycle.initializeServices(container);
+
+// ... use services ...
+
+// Manually shutdown services
+await lifecycle.shutdownServices(container);
+```
+
+### Legacy API (Backward Compatible)
+
+```typescript
+import { createServiceContainerFromConfig } from '@stock-bot/di';
+
+// Old way still works
+const container = createServiceContainerFromConfig(appConfig, {
+  enableQueue: true,
+  enableCache: true
+});
+
+// Manual initialization required with legacy API
+await initializeServices(container);
+```
+
+## Migration Guide
+
+1. Replace direct container creation with `ServiceContainerBuilder`
+2. Use `CacheFactory` instead of manually creating `NamespacedCache`
+3. Let the builder handle service initialization automatically
+4. Use typed configuration schemas for better validation

+# @stock-bot/event-bus
+
+Lightweight event bus for inter-service communication in the Stock Bot platform.
+
+## Overview
+
+This library provides a simple pub/sub event system using Redis, designed for real-time event distribution between microservices. It focuses on simplicity and reliability for event-driven communication.
+
+## Features
+
+- Simple pub/sub pattern using Redis
+- Automatic reconnection and resubscription
+- Local event emission (works even without Redis)
+- TypeScript support with predefined trading event types
+- Lightweight with minimal dependencies
+
+## Installation
+
+```bash
+bun add @stock-bot/event-bus
+```
+
+## Usage
+
+### Basic Setup
+
+```typescript
+import { createEventBus, TradingEventType } from '@stock-bot/event-bus';
+
+const eventBus = createEventBus({
+  serviceName: 'data-ingestion',
+  redisConfig: {
+    host: 'localhost',
+    port: 6379,
+  },
+  enableLogging: true,
+});
+
+// Wait for connection
+await eventBus.waitForConnection();
+```
+
+### Publishing Events
+
+```typescript
+// Publish a price update
+await eventBus.publish(TradingEventType.PRICE_UPDATE, {
+  symbol: 'AAPL',
+  price: 150.25,
+  volume: 1000000,
+  timestamp: Date.now(),
+});
+
+// Publish with metadata
+await eventBus.publish(TradingEventType.ORDER_FILLED, 
+  {
+    orderId: '12345',
+    symbol: 'TSLA',
+    side: 'buy',
+    quantity: 100,
+    price: 250.50,
+  },
+  { source: 'ib-gateway', region: 'us' }
+);
+```
+
+### Subscribing to Events
+
+```typescript
+// Subscribe to price updates
+await eventBus.subscribe(TradingEventType.PRICE_UPDATE, async (message) => {
+  console.log(`Price update for ${message.data.symbol}: $${message.data.price}`);
+});
+
+// Subscribe to order events
+await eventBus.subscribe(TradingEventType.ORDER_FILLED, async (message) => {
+  const { orderId, symbol, quantity, price } = message.data;
+  console.log(`Order ${orderId} filled: ${quantity} ${symbol} @ $${price}`);
+});
+```
+
+### Event Types
+
+The library includes predefined event types for common trading operations:
+
+```typescript
+enum TradingEventType {
+  // Market data events
+  PRICE_UPDATE = 'market.price.update',
+  ORDERBOOK_UPDATE = 'market.orderbook.update',
+  TRADE_EXECUTED = 'market.trade.executed',
+  
+  // Order events
+  ORDER_CREATED = 'order.created',
+  ORDER_FILLED = 'order.filled',
+  ORDER_CANCELLED = 'order.cancelled',
+  ORDER_REJECTED = 'order.rejected',
+  
+  // Position events
+  POSITION_OPENED = 'position.opened',
+  POSITION_CLOSED = 'position.closed',
+  POSITION_UPDATED = 'position.updated',
+  
+  // Strategy events
+  STRATEGY_SIGNAL = 'strategy.signal',
+  STRATEGY_STARTED = 'strategy.started',
+  STRATEGY_STOPPED = 'strategy.stopped',
+  
+  // Risk events
+  RISK_LIMIT_BREACH = 'risk.limit.breach',
+  RISK_WARNING = 'risk.warning',
+  
+  // System events
+  SERVICE_STARTED = 'system.service.started',
+  SERVICE_STOPPED = 'system.service.stopped',
+  SERVICE_ERROR = 'system.service.error',
+}
+```
+
+### Typed Events
+
+Use TypeScript generics for type-safe event handling:
+
+```typescript
+import type { PriceUpdateEvent, OrderEvent } from '@stock-bot/event-bus';
+
+// Type-safe subscription
+await eventBus.subscribe<PriceUpdateEvent>(
+  TradingEventType.PRICE_UPDATE, 
+  async (message) => {
+    // message.data is typed as PriceUpdateEvent
+    const { symbol, price, volume } = message.data;
+  }
+);
+```
+
+### Cleanup
+
+```typescript
+// Unsubscribe from specific event
+await eventBus.unsubscribe(TradingEventType.PRICE_UPDATE);
+
+// Close all connections
+await eventBus.close();
+```
+
+## Architecture Notes
+
+This library is designed for lightweight, real-time event distribution. For reliable job processing, retries, and persistence, use the `@stock-bot/queue` library with BullMQ instead.
+
+### When to Use Event Bus
+
+- Real-time notifications (price updates, trade executions)
+- Service coordination (strategy signals, risk alerts)
+- System monitoring (service status, errors)
+
+### When to Use Queue
+
+- Data processing jobs
+- Batch operations
+- Tasks requiring persistence and retries
+- Scheduled operations
+
+## Error Handling
+
+The event bus handles connection failures gracefully:
+
+```typescript
+try {
+  await eventBus.publish(TradingEventType.PRICE_UPDATE, data);
+} catch (error) {
+  // Event will still be emitted locally
+  console.error('Failed to publish to Redis:', error);
+}
+```
+
+## Development
+
+```bash
+# Install dependencies
+bun install
+
+# Build
+bun run build
+
+# Run tests
+bun test
+
+# Clean build artifacts
+bun run clean
+```

+# @stock-bot/queue
+
+A reusable queue library with batch processing capabilities for the stock-bot project.
+
+## Features
+
+- **Queue Management**: Built on BullMQ with Redis backing
+- **Batch Processing**: Efficient processing of large datasets
+- **Provider Registry**: Pluggable job handler system
+- **Cache Integration**: Uses @stock-bot/cache for payload storage
+- **TypeScript Support**: Full type safety and IntelliSense
+- **Configurable**: Flexible configuration for different environments
+
+## Installation
+
+```bash
+npm install @stock-bot/queue
+```
+
+## Quick Start
+
+### Basic Queue Setup
+
+```typescript
+import { QueueManager, handlerRegistry } from '@stock-bot/queue';
+
+// Initialize queue manager (typically done via dependency injection)
+const queueManager = new QueueManager({
+  redis: {
+    host: 'localhost',
+    port: 6379,
+  },
+});
+
+// Get or create a queue
+const queue = queueManager.getQueue('my-service-queue', {
+  workers: 5,
+  concurrency: 20,
+});
+
+// Register handlers
+handlerRegistry.register('market-data', {
+  'fetch-price': async (payload) => {
+    // Handle price fetching
+    return { price: 100, symbol: payload.symbol };
+  },
+  'update-data': async (payload) => {
+    // Handle data updates
+    return { success: true };
+  },
+});
+
+// Queue is ready to use - no initialization needed
+```
+
+### Batch Processing
+
+```typescript
+import { processItems, initializeBatchCache } from '@stock-bot/queue';
+
+// Initialize cache first
+await initializeBatchCache();
+
+// Process items in batches
+const result = await processItems(
+  ['AAPL', 'GOOGL', 'MSFT'],
+  (symbol, index) => ({ symbol, timestamp: Date.now() }),
+  queueManager,
+  {
+    totalDelayMs: 60000, // 1 minute total
+    useBatching: true,
+    batchSize: 100,
+    priority: 1,
+    provider: 'market-data',
+    operation: 'fetch-price',
+  }
+);
+
+console.log(result);
+// {
+//   jobsCreated: 1,
+//   mode: 'batch',
+//   totalItems: 3,
+//   batchesCreated: 1,
+//   duration: 150
+// }
+```
+
+### Generic Processing
+
+```typescript
+import { processItems } from '@stock-bot/queue';
+
+const result = await processItems(
+  ['AAPL', 'GOOGL', 'MSFT'],
+  (symbol, index) => ({
+    symbol,
+    index,
+    timestamp: Date.now(),
+  }),
+  queueManager,
+  {
+    operation: 'live-data',
+    provider: 'yahoo',
+    totalDelayMs: 300000, // 5 minutes
+    useBatching: false,
+    priority: 1,
+  }
+);
+```
+
+## API Reference
+
+### QueueManager
+
+The main queue management class.
+
+#### Constructor
+
+```typescript
+new QueueManager(config?: QueueConfig)
+```
+
+#### Methods
+
+- `initialize()`: Initialize the queue and workers
+- `registerProvider(name, config)`: Register a job provider
+- `add(name, data, options)`: Add a single job
+- `addBulk(jobs)`: Add multiple jobs in bulk
+- `getStats()`: Get queue statistics
+- `pause()`: Pause job processing
+- `resume()`: Resume job processing
+- `clean(grace, limit)`: Clean completed/failed jobs
+- `shutdown()`: Shutdown the queue manager
+
+### Batch Processing Functions
+
+#### processItems()
+
+Process items either directly or in batches.
+
+```typescript
+processItems<T>(
+  items: T[],
+  processor: (item: T, index: number) => any,
+  queue: QueueManager,
+  options: ProcessOptions
+): Promise<BatchResult>
+```
+
+#### processBatchJob()
+
+Process a batch job (used internally by workers).
+
+```typescript
+processBatchJob(
+  jobData: BatchJobData,
+  queue: QueueManager
+): Promise<any>
+```
+
+### Provider Registry
+
+Manage job handlers for different providers.
+
+```typescript
+// Register provider
+providerRegistry.register('provider-name', {
+  'operation-1': async (payload) => { /* handle */ },
+  'operation-2': async (payload) => { /* handle */ },
+});
+
+// Check provider exists
+if (providerRegistry.hasProvider('provider-name')) {
+  // Provider is registered
+}
+
+// Get handler
+const handler = providerRegistry.getHandler('provider-name', 'operation-1');
+```
+
+## Configuration
+
+### QueueConfig
+
+```typescript
+interface QueueConfig {
+  workers?: number;           // Number of worker processes
+  concurrency?: number;       // Jobs per worker
+  redis?: {
+    host?: string;
+    port?: number;
+    password?: string;
+    db?: number;
+  };
+  queueName?: string;         // Name for the queue
+  defaultJobOptions?: {
+    removeOnComplete?: number;
+    removeOnFail?: number;
+    attempts?: number;
+    backoff?: {
+      type: string;
+      delay: number;
+    };
+  };
+}
+```
+
+### ProcessOptions
+
+```typescript
+interface ProcessOptions {
+  totalDelayMs: number;       // Total time to spread jobs over
+  batchSize?: number;         // Items per batch (batch mode)
+  priority?: number;          // Job priority
+  useBatching?: boolean;      // Use batch vs direct mode
+  retries?: number;           // Number of retry attempts
+  ttl?: number;               // Cache TTL for batch payloads
+  removeOnComplete?: number;  // Keep N completed jobs
+  removeOnFail?: number;      // Keep N failed jobs
+  provider?: string;          // Provider name for job routing
+  operation?: string;         // Operation name for job routing
+}
+```
+
+## Migration from Existing Queue
+
+If you're migrating from an existing queue implementation:
+
+1. **Replace imports**:
+   ```typescript
+   // Before
+   import { QueueService } from '../services/queue.service';
+   import { processItems } from '../utils/batch-helpers';
+   
+   // After
+   import { QueueManager, processItems } from '@stock-bot/queue';
+   ```
+
+2. **Update initialization**:
+   ```typescript
+   // Before
+   const queueService = new QueueService();
+   await queueService.initialize();
+   
+   // After
+   const queueManager = new QueueManager({
+     redis: { host: 'localhost', port: 6379 }
+   });
+   // No initialization needed
+   ```
+
+3. **Update provider registration**:
+   ```typescript
+   // Before
+   providerRegistry.register('provider', config);
+   
+   // After
+   handlerRegistry.register('provider', config);
+   ```
+
+## Examples
+
+See the `/examples` directory for complete implementation examples:
+
+- `basic-usage.ts` - Basic queue setup and job processing
+- `batch-processing.ts` - Advanced batch processing scenarios
+- `provider-setup.ts` - Provider registration patterns
+- `migration-example.ts` - Migration from existing queue service
+
+## Best Practices
+
+1. **Initialize cache before batch operations**:
+   ```typescript
+   await initializeBatchCache();
+   ```
+
+2. **Use appropriate batch sizes**:
+   - Small items: 500-1000 per batch
+   - Large items: 50-100 per batch
+
+3. **Set reasonable delays**:
+   - Spread jobs over time to avoid overwhelming services
+   - Consider rate limits of external APIs
+
+4. **Clean up periodically**:
+   ```typescript
+   const queue = queueManager.getQueue('my-queue');
+   await queue.clean(24 * 60 * 60 * 1000); // Clean jobs older than 24h
+   ```
+
+5. **Monitor queue stats**:
+   ```typescript
+   const queue = queueManager.getQueue('my-queue');
+   const stats = await queue.getStats();
+   console.log('Queue status:', stats);
+   ```
+
+## Environment Variables
+
+- `WORKER_COUNT`: Number of worker processes (default: 5)
+- `WORKER_CONCURRENCY`: Jobs per worker (default: 20)
+- `DRAGONFLY_HOST`: Redis/Dragonfly host (default: localhost)
+- `DRAGONFLY_PORT`: Redis/Dragonfly port (default: 6379)
+- `DRAGONFLY_PASSWORD`: Redis/Dragonfly password
+- `DRAGONFLY_DB`: Redis/Dragonfly database number (default: 0)

-```typescript
-import { HttpClient } from '@stock-bot/http';
-import { logger } from '@stock-bot/logger';
-
-const client = new HttpClient({
-  baseURL: 'https://api.example.com',
-  timeout: 10000, // 10 seconds
-  retries: 3,
-  retryDelay: 1000, // 1 second base delay
-  defaultHeaders: {
-    'Authorization': 'Bearer token',
-    'User-Agent': 'Stock-Bot/1.0'
-  },
-  validateStatus: (status) => status < 400
-}, logger);
-```
-
-## Proxy Support
-
-### HTTP/HTTPS Proxy
-
-```typescript
-const client = new HttpClient({
-  proxy: {
-    type: 'http',
-    host: 'proxy.example.com',
-    port: 8080,
-    username: 'user', // optional
-    password: 'pass'  // optional
-  }
-});
-```
-
-### SOCKS Proxy
-
-```typescript
-const client = new HttpClient({
-  proxy: {
-    type: 'socks5',
-    host: 'socks-proxy.example.com',
-    port: 1080,
-    username: 'user', // optional
-    password: 'pass'  // optional
-  }
-});
-```
-
-## Rate Limiting
-
-```typescript
-const client = new HttpClient({
-  rateLimit: {
-    maxRequests: 100,           // Max 100 requests
-    windowMs: 60 * 1000,        // Per 1 minute
-    skipSuccessfulRequests: false,
-    skipFailedRequests: true    // Don't count failed requests
-  }
-});
-
-// Check rate limit status
-const status = client.getRateLimitStatus();
-console.log(`${status.currentCount}/${status.maxRequests} requests used`);
-```
-
-## Request Methods
-
-```typescript
-// GET request
-const getData = await client.get('/api/data');
-
-// POST request with body
-const postData = await client.post('/api/users', {
-  name: 'John',
-  email: 'john@example.com'
-});
-
-// PUT request
-const putData = await client.put('/api/users/1', updatedUser);
-
-// DELETE request
-const deleteData = await client.delete('/api/users/1');
-
-// PATCH request
-const patchData = await client.patch('/api/users/1', { name: 'Jane' });
-
-// Custom request
-const customResponse = await client.request({
-  method: 'POST',
-  url: '/api/custom',
-  headers: { 'X-Custom': 'value' },
-  body: { data: 'custom' },
-  timeout: 5000
-});
-```
-
-## Error Handling
-
-```typescript
-import { HttpError, TimeoutError, RateLimitError } from '@stock-bot/http';
-
-try {
-  const response = await client.get('/api/data');
-} catch (error) {
-  if (error instanceof TimeoutError) {
-    console.log('Request timed out');
-  } else if (error instanceof RateLimitError) {
-    console.log(`Rate limited: retry after ${error.retryAfter}ms`);
-  } else if (error instanceof HttpError) {
-    console.log(`HTTP error ${error.status}: ${error.message}`);
-  }
-}
-```
-
-## Retry Configuration
-
-```typescript
-const client = new HttpClient({
-  retries: 3,           // Retry up to 3 times
-  retryDelay: 1000,     // Base delay of 1 second
-  // Exponential backoff: 1s, 2s, 4s
-});
-
-// Or per-request retry configuration
-const response = await client.get('/api/data', {
-  retries: 5,
-  retryDelay: 500
-});
-```
-
-## Timeout Handling
-
-```typescript
-// Global timeout
-const client = new HttpClient({
-  timeout: 30000 // 30 seconds
-});
-
-// Per-request timeout
-const response = await client.get('/api/data', {
-  timeout: 5000 // 5 seconds for this request
-});
-```
-
-## Custom Status Validation
-
-```typescript
-const client = new HttpClient({
-  validateStatus: (status) => {
-    // Accept 2xx and 3xx status codes
-    return status >= 200 && status < 400;
-  }
-});
-
-// Or per-request validation
-const response = await client.get('/api/data', {
-  validateStatus: (status) => status === 200 || status === 404
-});
-```
-
-## TypeScript Support
-
-The library is fully typed with TypeScript:
-
-```typescript
-interface User {
-  id: number;
-  name: string;
-  email: string;
-}
-
-// Response data is properly typed
-const response = await client.get<User[]>('/api/users');
-const users: User[] = response.data;
-
-// Request configuration is validated
-const config: RequestConfig = {
-  method: 'POST',
-  url: '/api/users',
-  body: { name: 'John' },
-  timeout: 5000
-};
-```
-
-## Integration with Logger
-
-```typescript
-import { logger } from '@stock-bot/logger';
-import { HttpClient } from '@stock-bot/http';
-
-const client = new HttpClient({
-  baseURL: 'https://api.example.com'
-}, logger);
-
-// All requests will be logged with debug/warn/error levels
-```
-
-## Testing
-
-```bash
-# Run tests
-bun test
-
-# Run with coverage
-bun test --coverage
-
-# Watch mode
-bun test --watch
-```

+# Stock Bot Coverage CLI
+
+A custom coverage tool for the Stock Bot monorepo that provides advanced coverage reporting with support for excluding directories (like `dist/`) and beautiful reporting options.
+
+## Features
+
+- 🚫 **Exclusion Support**: Exclude directories like `dist/`, `node_modules/`, and test files from coverage
+- 📊 **Multiple Reporters**: Terminal, HTML, JSON, and Markdown reports
+- 🎯 **Threshold Enforcement**: Set and enforce coverage thresholds
+- 📦 **Monorepo Support**: Works seamlessly with workspace packages
+- 🎨 **Beautiful Reports**: Interactive HTML reports and colored terminal output
+- 🔧 **Configurable**: Use `.coveragerc.json` or CLI flags
+
+## Installation
+
+The tool is already part of the Stock Bot monorepo. Just run:
+
+```bash
+bun install
+```
+
+## Usage
+
+### Basic Usage
+
+Run coverage for all packages:
+
+```bash
+bun run coverage
+```
+
+### Generate HTML Report
+
+```bash
+bun run coverage:html
+```
+
+### CI Mode
+
+Generate markdown and JSON reports, fail if below threshold:
+
+```bash
+bun run coverage:ci
+```
+
+### Run for Specific Packages
+
+```bash
+bun run coverage --packages core utils
+```
+
+### Custom Exclusions
+
+```bash
+bun run coverage --exclude "**/dist/**" "**/generated/**" "**/vendor/**"
+```
+
+### Set Thresholds
+
+```bash
+bun run coverage --threshold 85 --threshold-functions 80
+```
+
+## Configuration
+
+Create a `.coveragerc.json` file in your project root:
+
+```json
+{
+  "exclude": [
+    "**/node_modules/**",
+    "**/dist/**",
+    "**/build/**",
+    "**/coverage/**",
+    "**/*.test.ts",
+    "**/*.test.js",
+    "**/test/**",
+    "**/tests/**"
+  ],
+  "reporters": ["terminal", "html"],
+  "thresholds": {
+    "lines": 80,
+    "functions": 80,
+    "branches": 80,
+    "statements": 80
+  },
+  "outputDir": "coverage"
+}
+```
+
+Or create one with:
+
+```bash
+bun run coverage init
+```
+
+## Reporters
+
+### Terminal Reporter
+
+Beautiful colored output in your terminal:
+
+```
+═══════════════════════════════════════════════════════════
+          Stock Bot Coverage Report
+═══════════════════════════════════════════════════════════
+
+┌────────────────┬──────────┬──────────┬──────────┬────────────┐

+⚠ 2 packages below threshold
+```
+
+### HTML Reporter
+
+Interactive HTML report with:
+- Package breakdown
+- File-level coverage
+- Beautiful charts and visualizations
+- Responsive design
+
+### Markdown Reporter
+
+Perfect for CI/CD comments on pull requests:
+- Summary tables
+- Package details
+- Threshold status
+- File breakdowns
+
+### JSON Reporter
+
+Machine-readable format for:
+- Custom tooling integration
+- Historical tracking
+- CI/CD pipelines
+
+## CLI Options
+
+| Option | Description |
+|--------|-------------|
+| `-p, --packages <packages...>` | Run coverage for specific packages |
+| `-e, --exclude <patterns...>` | Glob patterns to exclude from coverage |
+| `-i, --include <patterns...>` | Glob patterns to include in coverage |
+| `-r, --reporters <reporters...>` | Coverage reporters to use |
+| `-t, --threshold <number>` | Set coverage threshold for all metrics |
+| `--threshold-lines <number>` | Set line coverage threshold |
+| `--threshold-functions <number>` | Set function coverage threshold |
+| `--threshold-branches <number>` | Set branch coverage threshold |
+| `--threshold-statements <number>` | Set statement coverage threshold |
+| `-o, --output-dir <path>` | Output directory for reports |
+| `-c, --config <path>` | Path to coverage config file |
+| `--fail-under` | Exit with non-zero code if below threshold |
+
+## How It Works
+
+1. **Test Execution**: Runs `bun test` for each package
+2. **Data Collection**: Currently simulates coverage data based on test results (Bun's coverage feature is not yet fully implemented)
+3. **Filtering**: Applies exclusion patterns to remove unwanted files
+4. **Processing**: Merges coverage data across packages
+5. **Reporting**: Generates reports in requested formats
+
+> **Note**: This tool currently generates simulated coverage data based on test results because Bun's `--coverage` flag doesn't yet produce LCOV output. Once Bun's coverage feature is fully implemented, the tool will be updated to use actual coverage data.
+
+## Why This Tool?
+
+Bun's built-in coverage tool lacks several features needed for large monorepos:
+- No way to exclude directories like `dist/`
+- Limited reporting options
+- No per-package thresholds
+- Basic terminal output
+
+This tool addresses these limitations while maintaining compatibility with Bun's test runner.
+
+## Contributing
+
+The coverage tool is located in `tools/coverage-cli/`. To work on it:
+
+1. Make changes in `tools/coverage-cli/src/`
+2. Test with `bun run coverage`
+3. Build with `bun build tools/coverage-cli/src/index.ts`
