|
||||
|
||||
## Action Plan
|
||||
|
||||
### Phase 1: Validate Existing Models (4 hours) ← START HERE
|
||||
**Run backtests to see if models already meet production targets**
|
||||
|
||||
```bash
|
||||
# MAMBA-2 (1h)
|
||||
cargo run -p backtesting_service --example backtest_mamba2 --release -- \
|
||||
--model-path ml/checkpoints/mamba2_dbn/best_model_epoch_10.safetensors \
|
||||
--data-path test_data/real/databento/ml_training \
|
||||
--symbol ES.FUT --start-date 2024-03-01 --end-date 2024-03-31 \
|
||||
--output-path backtests/mamba2_validation.json
|
||||
|
||||
# DQN (1h)
|
||||
cargo run -p backtesting_service --example backtest_dqn --release -- \
|
||||
--model-path ml/trained_models/dqn_final_epoch100.safetensors \
|
||||
--data-path test_data/real/databento/ml_training \
|
||||
--symbol ES.FUT --start-date 2024-03-01 --end-date 2024-03-31 \
|
||||
--output-path backtests/dqn_validation.json
|
||||
|
||||
# PPO (1h)
|
||||
cargo run -p backtesting_service --example backtest_ppo --release -- \
|
||||
--actor-path ml/trained_models/ppo_actor_epoch_20.safetensors \
|
||||
--critic-path ml/trained_models/ppo_critic_epoch_20.safetensors \
|
||||
--data-path test_data/real/databento/ml_training \
|
||||
--symbol ES.FUT --start-date 2024-03-01 --end-date 2024-03-31 \
|
||||
--output-path backtests/ppo_validation.json
|
||||
|
||||
# Analyze (1h)
|
||||
cargo run -p ml --example compare_backtest_results --release -- \
|
||||
--mamba2 backtests/mamba2_validation.json \
|
||||
--dqn backtests/dqn_validation.json \
|
||||
--ppo backtests/ppo_validation.json \
|
||||
--output backtests/model_comparison_report.md
|
||||
```
|
||||
|
||||
**Targets**:
|
||||
- Wave C: Sharpe ≥1.5, Win Rate ≥55%, Drawdown ≤20%
|
||||
- Wave D: Sharpe ≥2.0, Win Rate ≥60%, Drawdown ≤15%
|
||||
|
||||
**Decision**:
|
||||
- ✅ **ALL PASS** → Skip retraining, deploy immediately (Phase 5)
|
||||
- ⚠️ **SOME FAIL** → Retrain only failing models (Phase 3)
|
||||
- ❌ **ALL FAIL** → Full retraining (Phase 2 + 3)
|
||||
|
||||
---
|
||||
|
||||
### Phase 2: Fix Warmup Bug (2 hours) ← IF RETRAINING
|
||||
**Only if Phase 1 shows models need retraining**
|
||||
|
||||
**File**: `/home/jgrusewski/Work/foxhunt/common/src/ml_strategy.rs`
|
||||
|
||||
Add explicit warmup check in `extract_features()`:
|
||||
```rust
|
||||
if bars.len() <= WARMUP_PERIOD {
|
||||
return Err(CommonError::invalid_input(
|
||||
format!("Insufficient data: {} bars, need >{}", bars.len(), WARMUP_PERIOD)
|
||||
));
|
||||
}
|
||||
```
|
||||
|
||||
**Validate**:
|
||||
```bash
|
||||
cargo run -p ml --example validate_225_features_runtime --release
|
||||
cargo test -p ml --lib feature_extraction --release
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 3: Retrain Models (4-8 hours) ← ONLY IF NEEDED
|
||||
**Automated pipeline for all models**:
|
||||
```bash
|
||||
cargo run -p ml --example retrain_all_models --release -- \
|
||||
--models MAMBA2,DQN,PPO,TFT \
|
||||
--data-dir test_data/real/databento/ml_training \
|
||||
--output-dir ml/trained_models/quarterly_$(date +%Y%m%d) \
|
||||
--latest-days 90 \
|
||||
--min-sharpe 1.5 \
|
||||
--min-win-rate 0.55
|
||||
```
|
||||
|
||||
**Or individual models**:
|
||||
```bash
|
||||
# MAMBA-2 (1.7-3.3h)
|
||||
cargo run -p ml --example train_mamba2_dbn --release -- \
|
||||
--data-dir test_data/real/databento/ml_training \
|
||||
--epochs 50 --batch-size 32 --learning-rate 1e-4
|
||||
|
||||
# DQN (25-33min)
|
||||
cargo run -p ml --example train_dqn --release -- \
|
||||
--data-dir test_data/real/databento/ml_training \
|
||||
--episodes 100 --batch-size 64
|
||||
|
||||
# PPO (6-8min)
|
||||
cargo run -p ml --example train_ppo_extended --release -- \
|
||||
--data-dir test_data/real/databento/ml_training \
|
||||
--epochs 50 --batch-size 128
|
||||
|
||||
# TFT (1.5-2.5h)
|
||||
cargo run -p ml --example train_tft_dbn --release -- \
|
||||
--data-dir test_data/real/databento/ml_training \
|
||||
--epochs 30 --batch-size 64
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Phase 4: Validate Retrained (2 hours) ← AFTER RETRAINING
|
||||
```bash
|
||||
cargo test -p backtesting_service wave_d_backtest --release -- --nocapture
|
||||
```
|
||||
|
||||
**Targets**: Sharpe ≥2.0, Win Rate ≥60%, Drawdown ≤15%
|
||||
|
||||
---
|
||||
|
||||
### Phase 5: Production Deployment (4 hours) ← FINAL STEP
|
||||
```bash
|
||||
# 1. Apply database migration (regime detection tables)
|
||||
cargo sqlx migrate run
|
||||
|
||||
# 2. Deploy checkpoints
|
||||
mkdir -p ml/trained_models/production_$(date +%Y%m%d)
|
||||
cp ml/checkpoints/mamba2_dbn/best_model_epoch_10.safetensors \
|
||||
ml/trained_models/production_$(date +%Y%m%d)/mamba2.safetensors
|
||||
# ... (copy DQN, PPO, TFT)
|
||||
|
||||
ln -sfn production_$(date +%Y%m%d) ml/trained_models/production
|
||||
|
||||
# 3. Configure Grafana dashboards
|
||||
curl -X POST http://admin:foxhunt123@localhost:3000/api/dashboards/import \
|
||||
-H "Content-Type: application/json" \
|
||||
-d @grafana/dashboards/wave_d_regime_detection.json
|
||||
|
||||
# 4. Start paper trading
|
||||
tli trade ml regime --symbol ES.FUT
|
||||
tli trade ml start-predictions --interval 30 --symbols ES.FUT,NQ.FUT
|
||||
|
||||
# 5. Enable Prometheus alerts
|
||||
cp prometheus/alerts/wave_d_regime_detection.yml /etc/prometheus/alerts/
|
||||
curl -X POST http://localhost:9090/-/reload
|
||||
```

## Timeline Summary
|
||||
|
||||
| Scenario | Steps | Time | Cost |
|
||||
|---|---|---|---|
|
||||
| **Best Case** (models pass) | Phase 1 → Phase 5 | 8h (2 days) | $0 |
|
||||
| **Likely Case** (some fail) | Phase 1 → 2 → 3 → 4 → 5 | 16-18h (3 days) | $0 |
|
||||
| **Worst Case** (all fail) | Phase 1 → 2 → 3 → 4 → 5 | 17h (4 days) | $0 |
|
||||
|
||||
**Original estimate** (CLAUDE.md): 4-6 weeks (180-240 hours)
|
||||
**Revised estimate**: 8-17 hours (96-97% time savings)
|
||||

|
||||
|
||||
## Key Decisions
|
||||
|
||||
| Decision | Choice | Rationale |
|
||||
|---|---|---|
|
||||
| **Service vs. Examples?** | Use ML examples | Faster iteration, easier debugging |
|
||||
| **Local vs. Cloud GPU?** | Use local RTX 3050 Ti | $0 cost, available 24/7, 0 setup time |
|
||||
| **Validate vs. Retrain?** | Validate first (Phase 1) | Models already trained today, may pass |
|
||||
| **Existing vs. More Data?** | Use existing 360 files | Sufficient (180K bars), EXCELLENT quality |
|
||||
