jgrusewski 0cd1688327 🚀 Wave 127 Wave 1: Foundation Fixes (4 agents)
**Mission**: Close gap between Wave 126 "theoretical 100%" and operational readiness

**Agent 118: Database Schema** 
- Created migration 020_create_executions_table.sql
- Added executions table with 9 columns, 5 indexes
- Foreign key to orders table with CASCADE
- UNBLOCKED load testing (Agent 123)

**Agent 119: GPU Docker Configuration**  (USER PRIORITY)
- Updated docker-compose.yml with NVIDIA runtime
- Configured GPU environment variables for ML service
- Verified RTX 3050 Ti accessible (nvidia-smi working)
- CUDA 13.0 enabled in container
- SATISFIED user requirement: "Ensure GPU is working in docker"

**Agent 120: Prometheus HTTP Exporters** ⚠️ PARTIAL
- Added Prometheus dependencies to all 4 services
- Implemented /metrics endpoints with Axum HTTP servers
- Services compiled and running healthy
- ISSUE: HTTP endpoints not responding (needs investigation)

**Agent 121: Test Fixes** ⚠️ PARTIAL
- Fixed timing test in trading_engine (TSC availability check)
- Trading engine: 100% pass rate (298/298)
- NEW ISSUE: PPO continuous policy test failing (log probabilities)
- Overall: 99.83% pass rate (574/575 in ml crate)

**Wave 1 Results**:
- Critical path:  Database schema unblocked load testing
- User requirement:  GPU working in Docker
- Monitoring:  Prometheus needs fix
- Testing: ⚠️ 99.83% pass rate (1 new failure)

**Files Modified** (11):
- migrations/020_create_executions_table.sql (new)
- docker-compose.yml (GPU runtime)
- services/*/src/main.rs (4 files - Prometheus exporters)
- services/*/Cargo.toml (3 files - dependencies)
- trading_engine/src/timing.rs (test fix)

**Next**: Wave 2 - Execution Validation (6 agents)

Backtesting Service

Overview

The backtesting_service offers an independent and isolated environment for rigorously testing and validating trading strategies against historical market data. It provides a robust platform for simulating trading performance, analyzing strategy efficacy, and generating comprehensive performance reports before live deployment.

Features

  • Independent Backtesting Service: Operates autonomously, allowing for parallel and isolated strategy evaluations.
  • gRPC API for Backtest Execution: Exposes a clear API for submitting and managing backtesting jobs.
  • Strategy Testing and Validation: Enables comprehensive testing of various trading strategies under different market conditions.
  • Performance Reporting: Generates detailed reports including metrics like P&L, Sharpe ratio, drawdown, and win rate.
  • Data Replay Engine: Accurately replays historical market data, simulating real-world order book dynamics and trade execution.
  • Results Persistence: Stores backtesting results and reports for historical analysis and comparison.

gRPC API

The backtesting_service exposes a gRPC API for initiating and retrieving backtest results. Key endpoints include:

  • RunBacktest - Submit backtest configuration and strategy
  • GetBacktestResults - Retrieve results for completed backtests
  • ListAvailableStrategies - List registered strategies
  • GetBacktestReport - Get detailed performance report

Running the service

To run the backtesting_service binary:

cargo run --bin backtesting_service

Data Requirements

The service requires historical market data in Parquet format:

  • Data should be stored in the configured data directory
  • Supports tick data, order book snapshots, and OHLCV candles
  • Data must include instrument, timestamp, and price/quantity fields

Testing

To run the tests for the backtesting_service crate:

cargo test --package backtesting_service
