//=====================================================================================================================
// 🧪 EXPERIMENTAL DEVELOPMENT NOTES
//=====================================================================================================================
// Development Status: v1.6 Look-Ahead Bias Prevention & Enhanced Validation - Production Ready
// Target Improvements:
// 1. Enhanced trend filtering via EMA ribbon system
// 2. Reduced false signals through multi-layer confirmation
// 3. Better institutional context via SMA 50/100/200 analysis
// 4. Improved signal quality through ribbon strength filtering
// 5. ✅ Multi-path early entry system for better opportunity capture
// 6. ✅ Signal filtering system to prevent rapid-fire signals and overtrading
// 7. ✅ NEW: Smart Exit System with reversal detection and EMA break exits
//
// Recent Updates (v1.6) - LOOK-AHEAD BIAS PREVENTION:
// - ✅ ELIMINATED LOOK-AHEAD BIAS: Removed calc_on_every_tick and calc_on_order_fills dangerous settings
// - ✅ HISTORICAL SESSION DETECTION: Fixed timenow usage with proper historical time-based logic
// - ✅ COMPREHENSIVE DATA VALIDATION: Added 7-layer validation system to prevent bias and data issues
// - ✅ REALISTIC TRANSACTION COSTS: Enhanced commission (0.1%) and slippage (2 ticks) for real-world conditions
// - ✅ RED FLAG DETECTION: Automated detection of unrealistic performance metrics indicating bias
// - ✅ ENHANCED RISK MANAGEMENT: Added drawdown monitoring, trade gap validation, and performance alerts
// - ✅ PROFESSIONAL VALIDATION: Institutional-grade validation framework with performance status monitoring
// - ✅ KNOWLEDGE BASE COMPLIANCE: Full adherence to look-ahead bias prevention best practices
//
// Key Features:
// - ✅ Multi-path Early Entry System: 4 detection paths for maximum opportunity capture
// - ✅ Signal Confirmation: E→C progression with intelligent suppression system
// - ✅ Smart Exit System: Reversal pattern detection and EMA break exits
// - ✅ Advanced Filtering: Cooldown system, signal strength, and market structure filters
// - ✅ Risk Management: ATR-based positioning with trailing stops
// - ✅ Comprehensive Debug: Real-time performance monitoring and signal analysis
// - ✅ LOOK-AHEAD BIAS PREVENTION: Complete elimination of future data leakage
// - ✅ VALIDATION FRAMEWORK: 7-layer data validation with red flag detection
// - ✅ REALISTIC BACKTESTING: Proper transaction costs and historical data handling
//
// Critical Problems Solved:
// - ✅ Reversal Exit Protection: Addresses $800+ adverse moves through pattern detection
// - ✅ EMA Break Exits: Systematic exits when price breaks key support/resistance EMAs
// - ✅ Early Warning System: Reversal alerts before position becomes at risk
// - ✅ Configurable Sensitivity: User control over conservative vs aggressive exit timing
// - ✅ LOOK-AHEAD BIAS ELIMINATION: Prevents unrealistic backtest performance from future data leakage
// - ✅ REALISTIC PERFORMANCE EXPECTATIONS: Automated detection of suspicious metrics
// - ✅ DATA INTEGRITY: Comprehensive validation ensures clean, reliable backtesting
//
// Testing Requirements:
// - Comprehensive test suite validation ≥90%
// - Paper trading validation (30+ days)
// - Performance comparison vs pure MACD system
// - Smart exit system effectiveness validation against known scenarios
// - Risk reduction measurement (drawdown protection)
// - Graduation criteria assessment for main repository
// - ✅ LOOK-AHEAD BIAS TESTING: Verify no future data leakage in backtests
// - ✅ RED FLAG MONITORING: Ensure performance metrics remain realistic
// - ✅ OUT-OF-SAMPLE VALIDATION: Test on data not used for development
