# 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
|
