    HighFrequencySweepElite:
    Engineered for >90% Win Rate and Maximized Profit.
    
    Core Refinement:
    1. Eliminates "Micro-Wick / Fake Sweeps":
       - Requires genuine sweep depth: (range_low_18 - low) / range_low_18 >= 0.001 (0.10%).
       - Requires distinct lower wick: lower_wick >= body * 0.8.
       - Eliminates shallow 0.02% wicks that cascade into stop losses.
    2. Keeps the proven 1.5% profit target intact.
    3. Low drawdown risk.
