Pipsgrowth EX18116 TrendFollow — إكسبرت أدفايزر إكسبرت أدفايزر

// Pipsgrowth EX18116 TrendFollow — Execution Flow (from source analysis)
// Family: TrendFollow
// Multi-timeframe EMA trend-confluence system for XAUUSD. Confirms M15/H1/H4 EMA alignment before entering, sizes lots dynamically from ATR-based stop and risk percent, trails stops and enforces a max daily loss guard. Full 12-layer stack. 12 layers: REGIME, SIGNAL, ENTRY, CONFIRM, NO-TRADE, CAPITAL CAP, RISK, SIZING, MANAGE, EXIT, SCALING, OnTester

ON_INIT:
    Create indicator handles: standard set
    Initialize state variables
    Detect broker GMT offset

ON_TICK:
    1. Refresh indicator buffers (closed-bar shift=1)
    2. Manage existing positions:
       - Break-even check
       - ATR trailing stop
       - Profit lock ratchet
       - Time-based exit
       - Opposite-signal exit
    3. If new bar:
       a. ClassifyRegime() — ADX/ATR/BB regime detection
       b. NoTradeGate() checks:
          - Market open + session filter
          - Spread limit
          - Cooldown after loss
          - Consecutive loss limit
          - Kill switch
          - Max drawdown
          - Max concurrent positions
          - Daily/weekly loss limits
       c. GenerateSignal() — strategy-specific entry logic
       d. CheckConfirm() — HTF alignment + R:R + ADX minimum
       e. Calculate position size from risk %
       f. Execute with retry logic
       g. Mark bar to prevent duplicates

ON_TESTER:
    Custom fitness = weighted(RecoveryFactor, ROI, ProfitFactor, TradeCount, Sharpe, Drawdown)
