# Initial ML Model Training Plan - Small Scale Performance Testing
|
||||
|
||||
**Date**: 2025-10-20
|
||||
**Purpose**: Train models with minimal data to get actual performance numbers
|
||||
**Scope**: Small-scale, fast iteration testing
|
||||
**Duration**: ~2-4 hours total
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
We have **100% test pass rate** and a production-ready system. Before committing to full-scale training (4-6 weeks, $2-$4 in data costs), we'll do a small-scale training run using **existing test data** to validate:
|
||||
|
||||
1. **Training pipeline works end-to-end**
|
||||
2. **225-feature dimension is operational**
|
||||
3. **Regime-adaptive strategies integrate correctly**
|
||||
4. **Baseline performance metrics**
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Use Existing Test Data (0 cost, 30 minutes)
|
||||
|
||||
### Available Test Data
|
||||
|
||||
We already have real DBN test data in `test_data/`:
|
||||
- ES.FUT (E-mini S&P 500)
|
||||
- NQ.FUT (E-mini NASDAQ)
|
||||
- CL.FUT (Crude Oil)
|
||||
|
||||
### Quick Training Run
|
||||
|
||||
```bash
|
||||
# Check available test data
|
||||
ls -lh test_data/
|
||||
|
||||
# Train DQN (fastest model, ~15-20 seconds)
|
||||
cargo run -p ml --example train_dqn --release
|
||||
|
||||
# Train PPO (fast, ~7-10 seconds)

|
||||
```
|
||||
|
||||
**Expected Output**:
|
||||
- Model checkpoint files
|
||||
- Training loss curves
|
||||
- Initial inference latency metrics
|
||||
- Memory usage statistics
|
||||
|
||||
**Validation**:

|
||||
## Phase 2: Quick Backtest with Test Data (30 minutes)
|
||||
|
||||
### Run Wave D Backtest
|
||||
|
||||
```bash
|
||||
# Already passing 7/7 tests (Sharpe 2.00, Win Rate 60%, Drawdown 15%)
|
||||
cargo test -p backtesting_service integration_wave_d_backtest --release -- --nocapture
|
||||
|
||||
# Run wave comparison backtest (Wave C vs Wave D)
|
||||
cargo build -p backtesting_service --example wave_comparison --release
|
||||
cargo run -p backtesting_service --example wave_comparison --release
|
||||
```
|
||||
|
||||
**Expected Metrics** (from test data):
|
||||
- **Sharpe Ratio**: 1.5-2.5 range
|
||||
- **Win Rate**: 55-65%
|
||||
- **Max Drawdown**: 10-20%
|
||||
- **Trades/Day**: 5-15
|
||||
|
||||
**Validation**:
|
||||
- ✅ Wave D outperforms Wave C baseline
|
||||
- ✅ Regime detection triggers correctly
|
||||
- ✅ Adaptive position sizing applies (0.2x-1.5x range)
|
||||
- ✅ Dynamic stop-loss adjusts (1.5x-4.0x ATR range)
|
||||

|
||||
|
||||
## Decision Points
|
||||
|
||||
### After Phase 1 (Training)
|
||||
|
||||
**If all models train successfully**:
|
||||
→ Proceed to Phase 2 (Backtest)
|
||||
|
||||
**If training fails**:
|
||||
→ Debug issues (likely 225-feature dimension problem)
|
||||
→ Fix and re-run
|
||||
|
||||
### After Phase 2 (Backtest)
|
||||
|
||||
**If Sharpe ≥ 1.5, Win Rate ≥ 55%**:
|
||||
→ Proceed to Phase 3 (Live System)
|
||||
|
||||
**If Sharpe < 1.5 or Win Rate < 55%**:
|
||||
→ Consider Phase 4 (Minimal Data Purchase)
|
||||
→ Or proceed with full-scale training plan
|
||||
|
||||
### After Phase 3 (Live System)
|
||||
|
||||
**If all services operational**:
|
||||
→ System is production-ready for paper trading
|
||||
→ Can proceed directly to paper trading phase
|
||||
|
||||
**If issues found**:
|
||||
→ Document blockers
|
||||
→ Fix and re-test

|
||||
|
||||
## Risk Mitigation
|
||||
|
||||
### Risk 1: Test Data Insufficient
|
||||
|
||||
**Symptom**: Training completes too quickly (<1 sec), poor backtest metrics
|
||||
**Mitigation**: Proceed to Phase 4 (1-week minimal purchase)
|
||||
**Cost**: ~$0.50
|
||||
|
||||
### Risk 2: 225-Feature Dimension Mismatch
|
||||
|
||||
**Symptom**: Training fails with shape errors
|
||||
**Mitigation**: We already validated 100% with hard migration - should not occur
|
||||
**Fallback**: Check `common::features::FeatureVector225` integration
|
||||
|
||||
### Risk 3: Model Checkpoint Loading Fails
|
||||
|
||||
**Symptom**: Inference crashes after training
|
||||
**Mitigation**: Validate checkpoint format matches inference expectations
|
||||
**Debug**: Use `cargo test -p ml -- --nocapture` to see detailed errors
|
||||
|
||||
### Risk 4: Service Integration Issues
|
||||
|
||||
**Symptom**: Services can't communicate or crash on startup
|
||||
**Mitigation**: Check gRPC port conflicts, database connectivity
|
||||
**Debug**: Review service logs in each terminal
|
||||
