Strategy Orchestrator

Overview

The Strategy Orchestrator service coordinates the execution and lifecycle management of trading strategies within the stock-bot platform. It serves as the central orchestration engine that translates trading signals into executable orders while managing strategy state, performance monitoring, and risk integration.

Key Features

Strategy Lifecycle Management

Strategy Registration: Onboarding and configuration of trading strategies
Version Control: Management of strategy versions and deployments
State Management: Tracking of strategy execution state
Activation/Deactivation: Controlled enabling and disabling of strategies

Execution Coordination

Signal Processing: Consumes and processes signals from Signal Engine
Order Generation: Translates signals into executable trading orders
Execution Timing: Optimizes order timing based on market conditions
Multi-strategy Coordination: Manages interactions between strategies

Performance Monitoring

Real-time Metrics: Tracks strategy performance metrics in real-time
Alerting: Notifies on strategy performance anomalies
Execution Quality: Measures and reports on execution quality
Strategy Attribution: Attributes P&L to specific strategies

Risk Integration

Pre-trade Risk Checks: Validates orders against risk parameters
Position Tracking: Monitors strategy position and exposure
Risk Limit Enforcement: Ensures compliance with risk thresholds
Circuit Breakers: Implements strategy-specific circuit breakers
