// Pipsgrowth EX18049 TrendFollow — Execution Flow (from source analysis)
// Family: TrendFollow
// Closed-bar price candle + inlined Tillson T3 (zero-lag, GD-form from EMA(price,N) chain e1..e6) slope confirmation plus inlined Heikin-Ashi close smoothing. 12 mandatory layers wired into OnTick: REGIME, SIGNAL (HA+T3), ENTRY, CONFIRM, NO-TRADE, CAPITAL-ALLOCATION-CAP, RISK, SIZING, MANAGE/EXIT (BE + ATR trail + partial TP + regime-change + opposite-signal + time), SCALING (pyramid off, capped), EXEC, OnTester custom criterion. 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)
