-  All services compile successfully
-  Mock architecture validated as best practice
-  Performance benchmarks maintained

## Agent Reports Generated
- AGENT_C1-C5: Cleanup execution reports
- AGENT_M1-M20: Mock architecture analysis (1,366+ lines)

Wave 19.1.8 Implementation Status

Date: October 17, 2025 Status: READY TO IMPLEMENT Approach: Option B (Simplified In-Place Implementation)

Decision Rationale

After reviewing the codebase:

  • State variables already exist in common/ml_strategy.rs (lines 87-106)
  • ML crate has production implementations to reference (ml/features/extraction.rs)
  • Zero external dependencies preferred for <100μs latency requirement
  • Full control over performance optimization

Chose Option B over Option C (rust_ti) because:

  1. Avoids external dependency
  2. State structure already in place
  3. Can optimize for specific <100μs requirement
  4. Simpler integration with existing code

Current Feature Count

Existing: 18 features (lines 214-511 in common/src/ml_strategy.rs)

  • Features 1-3: price_return, short_ma, volatility
  • Features 4-5: volume_ratio, volume_ma_ratio
  • Features 6-7: hour, day_of_week
  • Feature 8: Williams %R
  • Feature 9: ROC
  • Feature 10: Ultimate Oscillator
  • Features 11-13: OBV, MFI, VWAP
  • Features 14-18: EMA norms and crosses

Target: 25 features (18 + 7 new indicators)

Missing 7 Indicators (To Implement)

1. RSI (Relative Strength Index)

  • State: rsi_avg_gain, rsi_avg_loss (already exists)
  • Period: 14
  • Formula: RSI = 100 - (100 / (1 + RS)), where RS = avg_gain / avg_loss
  • Normalization: Divide by 100 to get [0, 1]
  • Reference: ml/src/features/extraction.rs lines 1348-1368

2. MACD (Moving Average Convergence Divergence)

  • State: macd_ema_12, macd_ema_26, macd_signal (already exists)
  • Periods: 12, 26, 9 (signal)
  • Formula: MACD = EMA12 - EMA26, Signal = EMA9(MACD)
  • Normalization: (MACD / price).tanh()
  • Reference: ml/src/features/extraction.rs

3. MACD Signal

  • Separate feature for signal line
  • Normalization: (Signal / price).tanh()

4. Bollinger Bands Position

  • Calculate on-the-fly (no persistent state needed)
  • Period: 20
  • Formula: (price - middle) / (upper - lower), where:
    • middle = SMA(20)
    • upper = middle + 2*std
    • lower = middle - 2*std
  • Normalization: Already in [-1, 1] range

5. ATR (Average True Range)

  • State: atr (already exists)
  • Period: 14
  • Formula: ATR = EMA14(TR), where TR = max(high-low, |high-prev_close|, |low-prev_close|)
  • Normalization: ATR / price (percentage)

6. ADX (Average Directional Index)

  • State: adx, plus_di, minus_di (already exists)
  • Period: 14
  • Formula: Complex (requires +DI, -DI, DX calculation)
  • Normalization: Divide by 100

7. Stochastic Oscillator

  • State: stoch_k_history (already exists)
  • Periods: 14 (%K), 3 (%D smoothing)
  • Formula: %K = (Close - Low14) / (High14 - Low14) * 100
  • Normalization: Divide by 100

8. CCI (Commodity Channel Index)

  • Calculate on-the-fly (no persistent state needed)
  • Period: 20
  • Formula: CCI = (Typical Price - SMA20) / (0.015 * Mean Deviation)
  • Normalization: (CCI / 200).tanh()

Implementation Plan

Files to Modify

  1. common/src/ml_strategy.rs:

    • Add calculation logic after line 507 (after EMA features)
    • Update feature capacity to 25 (line 156)
    • Add Bollinger/CCI temporary state variables if needed
  2. common/tests/ml_strategy_integration_tests.rs:

    • Change assertion from 18 → 25 features (line 49)
    • Update test comments (lines 31-46)

Implementation Sequence

  1. RSI (simplest - just averages)
  2. MACD + Signal (uses existing EMA logic)
  3. Bollinger Bands (SMA + stddev calculation)
  4. ATR (requires high/low simulation)
  5. Stochastic (similar to Williams %R)
  6. ADX (most complex)
  7. CCI (MAD calculation required)

Performance Target

  • Current: ~2ms per extraction (estimated from 18 features)
  • Target: <1ms per extraction (25 features)
  • Strategy: O(1) incremental updates, avoid full recalculations

Testing Strategy

  1. Unit tests: Verify each indicator calculation
  2. Integration tests: Verify 25 features extracted
  3. Range validation: All features in [-1, 1]
  4. Performance test: <1ms latency

Next Steps

  1. Implement 7 indicators in extract_features method
  2. Update tests to expect 25 features
  3. Run integration tests with real DBN data
  4. Validate performance benchmarks

Implementation Ready: YES Estimated Time: 4-6 hours Risk Level: LOW (state variables already exist, reference implementations available)
