// Pipsgrowth EX18071 TrendFollow — Execution Flow (from source analysis)
// Family: TrendFollow
// Core signal = perfect stacked alignment of 4 EMAs (10/20/50/200) on the last CLOSED bar. Entries are gated by an ADX+ATR-pctile+BB-width regime filter, HTF trend agreement, session window, spread filter, and a per-magic daily-loss / capital-cap governor. SL/TP are ATR-based, sized off the EFFECTIVE capital. In-trade: BE, partial TP at TP1, ATR trail, regime-change exit, time exit. Pyramiding default OFF. 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)
