    Ultra-Fast Scalping Strategy
    
    This strategy is designed for extremely short-term scalping on 1-minute timeframes.
    It uses momentum indicators and quick reversals for very fast entries and exits.
    
    Key Features:
    - 1-minute timeframe for maximum speed
    - Uses RSI, MACD, and Bollinger Bands
    - Very tight stops (0.1-0.2%)
    - Maximum hold time of 5-10 minutes
    - Volume and momentum confirmation
    
    Expected Performance:
    - Very high frequency trading
    - Small profits per trade (0.1-0.3%)
    - Requires excellent execution and low spreads
    - Best during high volatility periods
