Agent BACKTEST-01: Quick Summary

Date: 2025-10-19 Agent: BACKTEST-01 (Wave Comparison Backtest Validator) Status: ✅ COMPLETE - Critical gap identified

---

🎯 Mission

Validate Wave Comparison Backtest functionality for Wave C (201 features) vs Wave D (225 features) performance comparison.

---

🔍 Key Findings

✅ WORKING Components

1. Wave Comparison Framework Exists

   • File: wave_comparison.rs (584 lines)
   • Metrics: 11 performance metrics tracked
   • Export: JSON + CSV output
   • Tests: 2/2 unit tests passing

2. Performance Metrics Validated

   • Win rate (percentage)
   • Sharpe ratio (absolute)
   • Sortino ratio (absolute)
   • Maximum drawdown (percentage)
   • Total PnL (percentage)
   • 6 additional metrics

3. Regime-Adaptive Testing Exists

   • File: wave_d_regime_backtest_test.rs (521 lines)
   • 5 TDD tests (RED phase)
   • Position sizing: 0.2x-1.5x validated
   • Stop-loss: 1.5x-4.0x ATR validated

4. Feature Configuration Complete

   • Wave C: 201 features ✅
   • Wave D: 225 features (201 + 24) ✅
   • Wave D features: CUSUM (10), ADX (5), Transitions (5), Adaptive (4)

❌ CRITICAL GAPS

1. Wave D NOT in Wave Comparison

   pub struct WaveComparisonResults {
       pub wave_a: WavePerformanceMetrics,  // 26 features ✅
       pub wave_b: WavePerformanceMetrics,  // 36 features ✅
       pub wave_c: WavePerformanceMetrics,  // 201 features ✅
       // ❌ MISSING: pub wave_d: WavePerformanceMetrics (225 features)
   }
   

2. Mock Data Only (No Real Backtests)

   • Line 248: Hardcoded performance targets
   • No DBN data integration
   • No ML strategy engine connection

3. Feature Count Mismatch

   • Wave C shows 65 features (line 189)
   • Should be 201 features

4. Regime-Adaptive NOT in Comparison

   • Tested separately
   • Not integrated with WaveComparisonBacktest

🔧 Integration Roadmap

Phase 1: Add Wave D (2 hours)

• Extend WaveComparisonResults struct
• Add C→D improvement calculations
• Update CSV/JSON exports

Phase 2: DBN Data (1 hour)

• Replace load_market_data() mock
• Use DbnDataSource (already exists)
• Load ES.FUT, NQ.FUT, 6E.FUT, ZN.FUT

Phase 3: ML Strategy (2 hours)

• Replace run_wave_backtest() mock
• Use MLStrategyEngine.execute_ml_backtest()
• Enable regime-adaptive for Wave D

Phase 4: Fix Counts (30 minutes)

• Wave C: 65 → 201 features
• Wave D: Add 225 features
• Update all assertions

Phase 5: Testing (1 hour)

• Run full backtests
• Validate improvements
• Generate reports

Total Time: 6.5 hours

🎯 Impact

Blocker for Next Priority

From CLAUDE.md:

Priority 2: ML Model Retraining with 225 Features (4-6 weeks)

• Expected improvement: +25-50% Sharpe ratio

Problem: Cannot validate +25-50% Sharpe improvement hypothesis without Wave D in backtest comparison.

Recommendation: BLOCK ML retraining (Priority 2) until Wave Comparison Backtest can validate Wave D performance.

📈 Expected Wave D Improvements

Metric	Wave C (201)	Wave D (225)	Improvement
Sharpe Ratio	1.5	1.875-2.25	+25-50%
Win Rate	55%	60.5-63.25%	+10-15%
Max Drawdown	18%	12.6-14.4%	-20-30%

🚦 Status

Current State: ⚠️ PARTIALLY OPERATIONAL (Wave A/B/C only)

Blocking Issues: 4 P0 gaps identified

Time to Fix: 6.5 hours of focused development

Next Steps:

1. Assign developer to implement Wave D integration
2. Run validation tests with real DBN data
3. Compare Wave C vs Wave D performance
4. Proceed with ML retraining (Priority 2) if targets met

Key Takeaway: Wave Comparison Backtest exists but only covers Wave A/B/C. Wave D (225 features) integration is CRITICAL for validating the +25-50% Sharpe improvement hypothesis before proceeding with 4-6 week ML retraining effort.
