        Personalized Trading Strategy with Risk Management, DCA, and Technical Indicators

        This automated strategy combines advanced risk management techniques with Dollar Cost Averaging (DCA)
        to optimize market operations. The strategy employs technical indicators (e.g., ADX, PDI, MDI) to define entry
        and exit conditions for both long and short positions. It also includes dynamic stoploss logic based on ATR and
        protections like cooldown periods and loss guards.

        Key features:
        - Long and short trading enabled with dynamic position adjustments.
        - Protections against overtrading using cooldown mechanisms.
        - Use of technical indicators to track market trends and trigger signals.
        - Supports dynamic stake adjustments based on successful trade entries.

        NOTE: This strategy is under development, and some functions may be disabled or incomplete. Parameters like ROI
        targets and advanced stoploss logic are subject to future optimization. Test thoroughly before using it in live trading.
