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:

    # 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
