## 🚀 Run Tests
```bash
# Run all ML pipeline integration tests
cargo test -p foxhunt_e2e --test ml_pipeline_integration_test
# Run with output
cargo test -p foxhunt_e2e --test ml_pipeline_integration_test -- --nocapture
# Run single test
cargo test -p foxhunt_e2e --test ml_pipeline_integration_test test_full_ml_pipeline_end_to_end
```

## 🔧 Pipeline Stages
```
1. Data Ingestion → Load DBN binary files
2. Feature Engineering → Extract 16 technical indicators
3. ML Prediction → Generate ensemble predictions (mock)
4. Trading Agent → Universe/Asset/Allocation decisions
5. Order Generation → Create executable orders
6. Trading Execution → Execute orders (simulated)
7. Backtesting → Calculate performance metrics
```

## 🔄 Mock vs Real
### Current (Mock)
- **Strategy**: Moving Average Crossover (5 vs 20 period)
- **Purpose**: Validate infrastructure
- **Performance**: <1ms per prediction
- **Status**: ✅ All tests passing
### Next Wave (Real)
- **Models**: MAMBA-2, DQN, PPO, TFT (6 models total)
- **Purpose**: Production predictions
- **Expected**: 10-50ms per prediction (GPU)
- **Status**: ⏳ Pending trained checkpoints
---
## 📈 Usage Examples
### Load DBN Data
```rust
let bars = load_dbn_data("test_data/real/databento/ml_training/ES.FUT_ohlcv-1m_2024-03-25.dbn").await?;
// Returns: Vec<OhlcvBar> with timestamp, OHLCV, symbol
```
### Extract Features
```rust
let features = extract_features(&bars)?;
// Returns: Vec<Vec<f64>> - 16 features per bar
```
### Generate Predictions
```rust
let predictions = mock_ensemble_predictions(&bars, &features)?;
// Returns: Vec<f64> - prediction scores (0.0-1.0)
```
### Create Trading Decisions
```rust
let decisions = generate_trading_decisions(&predictions)?;
// Returns: Vec<TradingDecision> with action (Buy/Sell/Hold)
```

## 🐛 Known Issues
None! All 11 tests passing.

## 🎯 Next Steps
1. **Load Real Models** (Priority 1)
- Replace mock with MAMBA-2, DQN, PPO, TFT
- Test with trained checkpoints
- Validate GPU inference
2. **Expand Symbols** (Priority 2)
- Add NQ.FUT, 6E.FUT, GC.FUT
- Test multi-symbol coordination
- Validate cross-symbol strategies
3. **Real Trading Integration** (Priority 3)
- Connect to Trading Service gRPC
- Test paper trading execution
- Real-time market data streaming
4. **Production Deployment** (Priority 4)
- Add monitoring and alerts
- Production logging
- Error handling and recovery
