## Known Issues & Recommendations
|
|
|
|
### Critical Issues (Production Blockers)
|
|
|
|
**NONE** - All 3 production-ready models have zero blocking issues.
|
|
|
|
### Non-Blocking Issues
|
|
|
|
1. **Feature 211 (ADX) NaN Issue** (Priority P2, 2-4 hours)
|
|
- **Impact**: DQN uses 201 features instead of 225
|
|
- **Root cause**: ADX calculation produces NaN on zero-volatility bars
|
|
- **Fix**: Implement lazy initialization in `RegimeADXFeatures`
|
|
- **Benefit**: DQN will use full 225 features (+12% more data)
|
|
|
|
2. **TFT GPU Memory Constraint** (Priority P3, 1-2 days)
|
|
- **Impact**: TFT not production-ready
|
|
- **Solution**: Rent AWS/GCP A100 24GB GPU instance
|
|
- **Cost**: ~$20-40 for 1-2 days training
|
|
- **Timeline**: Wave 8
|
|
|
|
3. **Code Quality Warnings** (Priority P4, 15-20 hours)
|
|
- 2,358 clippy warnings
|
|
- 7 test functions need `async` keyword
|
|
- No impact on functionality
|
|

|
|
## Next Steps
|
|
|
|
### Immediate (1-2 weeks): Production Deployment
|
|
|
|
1. **Deploy 3 Models to Paper Trading**:
|
|
```bash
|
|
# Start all services
|
|
docker-compose up -d
|
|
|
|
# Load models
|
|
tli ml load-model --model mamba2 --path ml/checkpoints/mamba2_dbn/best_model_epoch_10.safetensors
|
|
tli ml load-model --model dqn --path ml/trained_models/dqn_final_epoch100.safetensors
|
|
tli ml load-model --model ppo --path ml/trained_models/ppo_actor_epoch_20.safetensors
|
|
|
|
# Start paper trading
|
|
tli trade ml start-predictions --interval 30 --symbols ES.FUT,NQ.FUT
|
|
```
|
|
|
|
2. **Monitor Performance**:
|
|
- Regime transitions (5-10 per day expected)
|
|
- Position sizing (0.2x-1.5x range)
|
|
- Stop-loss adjustments (1.5x-4.0x ATR)
|
|
- Sharpe ratio (target: 1.5-2.0)
|
|
- Win rate (target: 55-60%)
|
|
|
|
3. **Validate Wave D Features**:
|
|
- Track regime detection accuracy
|
|
- Monitor Kelly Criterion position sizing
|
|
- Validate dynamic stop-loss effectiveness
|
|
|
|
### Wave 8 (1-2 weeks): TFT Training & Refinement
|
|
|
|
1. **TFT Cloud GPU Training** (1-2 days, ~$40):
|
|
- Rent AWS p3.2xlarge (V100 16GB) or p3.8xlarge (A100 24GB)
|
|
- Train TFT with full 225-feature configuration
|
|
- Expected training time: 3-5 hours
|
|
- Save model and deploy to production
|
|
|
|
2. **Fix Feature 211 (ADX NaN)** (2-4 hours):
|
|
- Implement lazy ADX initialization
|
|
- Retrain DQN with full 225 features
|
|
- Validate +12% data improvement
|
|
|
|
3. **Wave Comparison Backtest** (1 week):
|
|
- Compare Wave C baseline (Sharpe 1.50) vs Wave D (current)
|
|
- Expected: +25-50% Sharpe, +10-15% win rate, -20-30% drawdown
|
|
- Validate C→D improvement: +0.50 Sharpe, +9.1% win rate
|
|
|
|
### Long-Term (1-3 months): Production Validation
|
|
|
|
1. **Paper Trading** (2-4 weeks):
|
|
- Monitor 24/7 with Grafana dashboards
|
|
- Track regime transitions, position sizing, stop-loss
|
|
- Validate rollback procedures
|
|
|
|
2. **Live Deployment** (after paper trading validation):
|
|
- Deploy to production with real capital
|
|
- Start with small position sizes (1-5% of target)
|
|
- Gradually increase exposure over 4-8 weeks
