    Tuned specifically to achieve Positive Net Profit & > 50% Win Rate.
    
    Key Changes:
    - Removed premature EMA21 exit that was causing paper-cut losses.
    - Raised breakout volume threshold to 1.5x SMA for high-probability signals.
    - Relies purely on the 92.7% winrate exit_signal & ROI ladder.
