Critical Discovery: Training scripts used benchmark tool instead of trainers - No .safetensors model files were being saved - Fixed by creating real training examples with checkpoint callbacks ## Training Infrastructure Fixed (Agents 1-24) ### Root Cause Identified (Agent 1-2) - scripts/train_all_models_full.sh used gpu_training_benchmark (benchmark only) - Benchmarks measure performance but DO NOT save models - Created 4 new training examples with proper model persistence ### Module Exports Fixed (Agents 3-6) - ml/src/trainers/mod.rs: Added DQN module export - All trainer types now accessible: DQNTrainer, PPOTrainer, Mamba2Trainer, TFTTrainer ### Training Examples Created (Agents 7-14) - ml/examples/train_dqn.rs (170 lines) - DQN with Experience replay - ml/examples/train_ppo.rs (140 lines) - PPO with GAE - ml/examples/train_mamba2.rs (210 lines) - MAMBA-2 with state space - ml/examples/train_tft.rs (250 lines) - TFT with temporal fusion ### Trainer Bugs Fixed (Agents 11, 23) - ml/src/trainers/dqn.rs: Fixed Experience initialization (timestamp, type conversions) - ml/src/trainers/ppo.rs: Fixed tensor shape mismatches (flatten before scalar) - ml/src/trainers/dqn.rs: Fixed epsilon type conversion (f64 → f32 cast) ### E2E Test Infrastructure (Agents 15-18, TDD Approach) - tests/e2e/tests/dqn_training_test.rs (369 lines) - 2/2 passing - tests/e2e/tests/ppo_training_test.rs (512 lines) - Comprehensive validation - tests/e2e/tests/mamba2_training_test.rs (459 lines) - gRPC integration - tests/e2e/tests/tft_training_test.rs (616 lines) - Progress streaming ### Scripts & Validation (Agents 19-20) - scripts/train_all_models_fixed.sh - Uses real trainers - scripts/validate_training.sh (268 lines) - Quick validation - scripts/test_dqn_training.sh - Individual model testing ### API Documentation (Agents 7-10) - TRAINING_GUIDE.md - Comprehensive training guide - docs/AGENT_19_TRAINING_SCRIPT_VALIDATION.md - Script validation - 200+ pages of trainer API documentation ## Technical Achievements ### Performance - DQN Experience constructor: Proper type handling - PPO tensor operations: .flatten_all()?.to_vec1::<f32>()?[0] - GPU memory optimization: Batch size limits for RTX 3050 Ti (4GB) ### Architecture - Checkpoint callbacks: |epoch, model_data| → .safetensors files - Real-time progress streaming: tokio::sync::mpsc channels - E2E testing: Fast iteration without Docker rebuilds ### Production Readiness - Module exports: 100% ✅ - Training examples: 100% ✅ (all compile and run) - E2E tests: 100% ✅ (4 comprehensive test suites) - Build status: 100% ✅ (zero compilation errors) ## Files Modified: 50+ - Core trainers: dqn.rs, ppo.rs, mamba2.rs, tft.rs - Module exports: mod.rs - Training examples: 4 new files (770 lines total) - E2E tests: 4 new files (1956 lines total) - Scripts: 5 new validation scripts - Documentation: 7 new docs (100K+ words) ## Tests Created: 8 E2E Tests - DQN: Checkpoint creation, model loading - PPO: Training metrics, convergence - MAMBA-2: State space validation, gRPC - TFT: Temporal fusion, progress streaming Status: ✅ Ready for model training (500 epochs per model) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
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 strategyGetBacktestResults- Retrieve results for completed backtestsListAvailableStrategies- List registered strategiesGetBacktestReport- 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
