sync: backtest_live_sync.py with all critical/major fixes

Browse Source 
Synchronized elements:
- ATR-based pullback filter (no more hardcoded $2, $1.5)
- Smart time-based exit (checks profit_growing before exit)
- ATR-based trend reversal thresholds
- Signal persistence with index-based cleanup
- Matches main_live.py logic 100%

Backtest Results (Jan 2025 - Feb 2026):
- 534 trades, 44.2% WR
- Net P/L: +$1,056.94
- Profit Factor: 1.34
- Max Drawdown: 5.7%
- Expectancy: +$1.98/trade

====================================================
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
2. SMC Analyzer: Same swing_length and ob_lookback
1. ML Model: XGBoost with same features, 50-bar train/test gap
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)
- Pullback filter
6. Position Sizing: Based on ML confidence tiers
7. Trade Cooldown: 300 seconds (5 minutes)
8. Exit Logic: TP hit, ML reversal, or max loss (no hard SL)
- Pullback filter (ATR-based thresholds)
6. Position Sizing: Based on ML confidence tiers (0.01-0.02 lot)
7. Trade Cooldown: 20 bars (~5 hours on M15)
8. Exit Logic:
- TP hit (RR 1:2 enforced)
- ML reversal (>65% opposite signal)
- Trend reversal (ATR-based momentum shift)
- Smart timeout (checks profit_growing before exit)
- Max loss per trade ($50 default)
