Known Issues & Resolutions

High Priority (Block Production Deployment)

Issue 1: Feature 223 Sharpe Ratio Edge Case ⚠️

• File: /home/jgrusewski/Work/foxhunt/ml/src/features/regime_adaptive.rs:217
• Test: test_feature_223_regime_conditioned_sharpe
• Issue: Sharpe ratio returns 0.0 when volatility is zero
• Root Cause: Division by zero when std=0
• Fix: Add minimum data check + std=0 handling
• Time: 15 minutes
• Impact: Feature 223 will return NaN in low-volatility periods
• Resolution:

  // Add zero-check before division
  if std_dev < 1e-8 || count < 2 {
      return 0.0; // Not enough data or zero volatility
  }
  let sharpe = (mean_return - risk_free_rate) / std_dev;
  

Issue 2: 6-Regime Transition Matrix Initialization ⚠️

• File: /home/jgrusewski/Work/foxhunt/ml/src/regime/transition_matrix.rs:45
• Test: test_regime_transition_features_new_6_regimes
• Issue: Matrix initialized with 4 regimes, not 6
• Root Cause: RegimeTransitionMatrix::new() defaults to 4 regimes
• Fix: Update constructor to accept num_regimes parameter
• Time: 20 minutes
• Impact: Cannot support custom regime sets (e.g., 6-regime model)
• Resolution:

  impl RegimeTransitionMatrix {
      pub fn new(num_regimes: usize, alpha: f64) -> Self {
          // Initialize with N x N matrix instead of hardcoded 4x4
          Self {
              matrix: vec![vec![0.0; num_regimes]; num_regimes],
              counts: vec![vec![0; num_regimes]; num_regimes],
              num_regimes,
              alpha,
              // ...
          }
      }
  }
  

Total High Priority Fix Time: 35 minutes

Low Priority (Test Data Generation Issues)

Issue 3: Ranging Detection Test Data ⚠️

• Test: test_ranging_detection
• Issue: No ranging bars detected in test data
• Root Cause: Test data has trending component, ADX >25
• Fix: Generate tight mean-reverting data with ±0.1% moves
• Time: 15 minutes

Issue 4: Ranging Market Detection ⚠️

• Test: test_ranging_market_detection
• Issue: ADX too high (46.8 vs. <25 expected)
• Root Cause: Test data has sustained directional moves
• Fix: Generate alternating +/- moves to neutralize ADX
• Time: 20 minutes

Issue 5: High Volatility Regime Detection ⚠️

• Test: test_get_volatility_regime_high
• Issue: Not detecting elevated volatility regime
• Root Cause: Test data volatility too low (±1% vs. ±10% needed)
• Fix: Generate ±10% price swings
• Time: 15 minutes

Issue 6: Low Volatility Regime Detection ⚠️

• Test: test_get_volatility_regime_low
• Issue: Not detecting low volatility regime
• Root Cause: Test data volatility too high (±0.5% vs. ±0.01% needed)
• Fix: Generate ±0.01% ranges (near-flat price action)
• Time: 10 minutes

Total Low Priority Fix Time: 60 minutes

Grand Total Fix Time: 95 minutes (1.6 hours)

Production Blockers Resolved (E21)

Blocker 1: Trading Service Compilation Error (P0 CRITICAL) ✅ RESOLVED

• Issue: get_regime_state and get_regime_transitions methods outside trait block
• Impact: Trading Service failed to compile
• Resolution: Moved methods inside impl TradingRepository for PgTradingRepository trait block
• Time: 15 minutes (E21)
• Status: ✅ RESOLVED (2.86s clean build)

Blocker 2: SQLX Cache Missing (P1 HIGH) ✅ RESOLVED

• Issue: 6 SQLX queries not cached for offline compilation
• Impact: CI/CD builds failed without database access
• Resolution: Generated SQLX cache files (.sqlx/*.json) using cargo sqlx prepare
• Time: 10 minutes (E21)
• Status: ✅ RESOLVED (6 cache files generated)

   • Wave C (201 features): Sharpe 1.2, Win Rate 52%, Max DD 15%
   • Wave D (225 features): Sharpe 1.5-1.8, Win Rate 55-60%, Max DD 10-12%
   • Improvement: +25-50% Sharpe, +3-8% win rate, -20-33% max drawdown

Week 6: Production Validation

1. Staging Deployment: Deploy to staging environment
2. Paper Trading: 1-2 weeks validation with real market data
3. Metric Tracking: Regime transitions, position sizing, stop-loss adjustments
4. Threshold Tuning: Adjust CUSUM, ADX, stability window based on real data

GPU Benchmark Decision

Option 1: Local Training (RTX 3050 Ti)

• Pros: Zero cost, immediate availability, proven performance
• Cons: Limited to 4GB VRAM, slower for large models
• Cost: $0
• Training Time: 1.86 min (MAMBA-2), 15s (DQN), 7s (PPO)

Option 2: Cloud Training (AWS EC2 p3.2xlarge with V100)

• Pros: 10-100x faster, 16GB VRAM, scalable
• Cons: $3.06/hour, setup overhead, data transfer costs
• Cost: ~$50-$100 for full retraining (16-32 hours)
• Training Time: 10-20s (MAMBA-2), <1s (DQN/PPO)

Recommendation: Start with local training (RTX 3050 Ti) for initial validation. Consider cloud if training time exceeds 2-3 hours or VRAM becomes a bottleneck.

Next Milestone

ML Model Retraining with 225 Features (4-6 weeks timeline):

1. Download training data (90-180 days, 4 symbols)
2. Retrain MAMBA-2, DQN, PPO, TFT with 225-feature set
3. Execute Wave comparison backtest (Wave C vs. Wave D)
4. Validate +25-50% Sharpe improvement hypothesis
5. Deploy to production after staging validation
