    Github_Sahillatif0_FreqTrade__LiquiditySweepPro15m__20261014_021940 (Macro Swing Reclaim Engine):
    Precision Macro Swing Reclaim Scalper optimized for >79% Win Rate and minimal drawdown.

    Key Edge:
    1. 6-Hour Structural Swing Low Sweep:
       Detects when price sweeps liquidity below the 24-candle rolling low on 15m.
    2. Instantaneous Institutional Reclaim:
       Candle close MUST reclaim cleanly back above the swing low on a bullish close.
    3. Wick Absorption Filter:
       Lower rejection shadow >= 60% of candle body (Hammer / Pinbar absorption).
    4. EMA 50 Discount Floor:
       Filters free-falling knives by requiring close > EMA50 * 0.975.
    5. BTC Waterfall Protection:
       Prevents entering altcoin sweeps when BTC 15m RSI < 28 or BTC is dumping below 50 EMA.
    6. Adaptive Trailing Profit Lock:
       Trailing stop activates at +2.4% gain, locking in +1.4% profit floor.
    7. Precision Breakeven Ratchet:
       At +1.2% profit -> lock +0.3% floor.
       At +2.2% profit -> lock +1.4% floor.
