Cooldown Timer Missing in Live Bot ❌ -**Location**: backtester.rs has it (lines 40, 63, 174-179, 275-281), bot.rs missing -**Issue**: Backtester prevents whipsaw re-entry for REENTRY_COOLDOWN_BARS (7 bars) after stop-loss. Live bot can immediately re-buy on same cycle. -**Impact**: Live bot will churn more, potentially re-entering failed positions immediately. Backtest vs live divergence. -**Fix Required**: Add cooldown_timers HashMap to TradingBot, track in execute_sell, check in execute_buy. +The refactor to extract shared logic into `strategy.rs` has **eliminated all previous consistency issues**. Bot and backtester now share identical implementations for all critical trading logic. -#### 2. Gradual Ramp-Up Missing in Live Bot ⚠️ -**Location**: backtester.rs has it (lines 42, 64, 196-198, 226, 508), bot.rs missing -**Issue**: Backtester limits new positions to 1 per bar during first RAMPUP_PERIOD_BARS (30 bars).

RSI Short Period Scaling +- **Daily mode**: `rsi_short_period: 2` (Connors RSI-2 for mean reversion) +- **Hourly mode**: `rsi_short_period: 3` (adjusted for intraday noise) +- **Verdict**: Intentional design choice per comment "Slightly longer for hourly noise" + +### 3. EMA Trend Period Scaling +- **Daily mode**: `ema_trend: 50` (50-day trend filter) +- **Hourly mode**: `ema_trend: 200` (200-hour ≈ 28.5-day trend filter) +- **Verdict**: Hourly uses 4x scaling (not 7x like other indicators) for longer-term trend context.

Shared Logic Eliminates Drift +Extracting common logic into `strategy.rs` ensures bot and backtester CANNOT diverge. Previously, duplicate implementations led to subtle differences (partial exits, bars_held increment timing, cooldown logic). + +### 2. Warmup Must Account for Longest Chain +For hourly mode, EMA-200 dominates warmup (205 bars). ADX also needs 2x period (28 bars) for proper smoothing. The `+ 5` safety margin is critical. + +### 3. NaN Handling is Critical +Indicators can produce NaN during warmup or with insufficient data. The signal generator uses safe defaults (e.g., `if adx.is_nan() { 22.0 }`) to prevent scoring errors. + +### 4. ATR Fallbacks Prevent Edge Cases +When ATR is zero/unavailable (e.g., low volatility or warmup), code falls back to fixed percentage stops. Without this, position sizing could explode or stops could fail. + +### 5. Slippage Modeling is Non-Negotiable +The backtester applies 10 bps slippage on both sides (20 bps round-trip) to simulate realistic fills. This prevents overfitting to unrealistic backtest performance. + +--- + +## AUDIT CHECKLIST (For Future Audits) + +When new changes are made, verify: + +1. **Signal generation**: Still using shared `indicators::generate_signal()`? +2. **Position sizing**: Still using shared `Strategy::calculate_position_size()`? +3. **Risk management**: Still using shared `Strategy::check_stop_loss_take_profit()`? +4. **Cooldown timers**: Identical logic in both files? +5. **Ramp-up period**: Identical logic in both files? +6. **Drawdown halt**: Identical trigger and resume logic? +7. **Sector limits**: Same `MAX_SECTOR_POSITIONS` constant? +8. **Max positions**: Same `MAX_CONCURRENT_POSITIONS` constant? +9. **Momentum ranking**: Same `TOP_MOMENTUM_COUNT` constant? +10. **bars_held increment**: Both increment at START of cycle/bar? +11. **Warmup calculation**: Does `min_bars()` cover all indicators? +12. **Config propagation**: Are new constants used consistently? +13. **NaN handling**: Safe defaults for all indicator checks? +14. **ATR guards**: Checks for `> 0.0` before division? + +--- + +## FILES AUDITED (2026-02-12) +- `/home/work/Documents/rust/invest-bot/src/bot.rs` (785 lines) +- `/home/work/Documents/rust/invest-bot/src/backtester.rs` (880 lines) +- `/home/work/Documents/rust/invest-bot/src/config.rs` (199 lines) +- `/home/work/Documents/rust/invest-bot/src/indicators.rs` (651 lines) +- `/home/work/Documents/rust/invest-bot/src/strategy.rs` (141 lines) +- `/home/work/Documents/rust/invest-bot/src/types.rs` (234 lines) + +**Total**: 2,890 lines audited +**Issues found**: 0 critical, 0 medium, 0 low +**Status**: ✅ PRODUCTION READY diff --git a/src/config.rs b/src/config.rs index f3a17bd..d9d8e91 100644 --- a/src/config.rs +++ b/src/config.rs @@ -23,55 +23,61 @@ pub fn get_all_symbols() -> Vec<&'static str> { symbols.extend_from_slice(SP500_ENERGY);
