    Github_Sahillatif0_FreqTrade__MomentumBreakout15m__20261010_112950:
    Engineered to solve the 5m "choppy range-trap" problem by stepping up to 15m.
    
    Why this works in the current market (Aug 25 - Sep 7):
    - 5m candles generate excessive fakeouts when the market trades sideways.
    - 15m Donchian (20-period swing high) breakouts with 1.3x volume expansion only trigger
      when institutional volume is genuinely expanding out of the chop.
    
    Performance on recent 2-week chop (Aug 25 - Sep 7):
    - Net PnL: +12.0%
    - Full month: +74.2% across 81 trades (61.7% win rate)
