 ====================================================
 This backtest MUST be identical to live trading logic.
 
+SYNCED with Critical & Major Fixes (Feb 2025):
+1. SMC Signal: No lookahead bias, current_close entry, min RR 2.0
+2. Pullback Filter: ATR-based thresholds (not hardcoded $2, $1.5)
+3. Time-Based Exit: Checks profit_growing + ML agreement before exit
+4. Trend Reversal: ATR-based momentum thresholds
+5. Signal Persistence: Index-based cleanup (prevents memory leak)
+6. Calibrated Confidence: Uses SMC's weighted confidence calculation
+
 Synchronized elements:
-1. ML Model: XGBoost with same features
+1. ML Model: XGBoost with same features, 50-bar train/test gap
-2. SMC Analyzer: Same swing_length and ob_lookback
+2. SMC Analyzer: Same swing_length, ob_lookback, NO LOOKAHEAD
 3. Regime Detection: HMM with MarketRegimeDetector
 4. Session Filter: Golden Time 19:00-23:00 WIB
 5. Signal Logic:
    - Skip if market quality AVOID or CRISIS
-   - ML confidence >= ML_THRESHOLD required
+   - ML confidence >= ML_THRESHOLD required (default 50%)
    - ML shouldn't strongly disagree (>65% opposite)
    - Signal confirmation (2+ consecutive signals)

-8. Exit Logic: TP hit, ML reversal, or max loss (no hard SL)
+8. Exit Logic:
