    MATRIX Strategy for FreqTrade.

    Integrates MATRIX ML pipeline with FreqTrade backtesting framework.

    IMPORTANT: This is a SANDBOX strategy for offline backtesting only.
    NO live trading, NO API calls, NO real money at risk.

    THRESHOLDS NOTE: Current hyperopt parameters use placeholder values.
    Real threshold values should be determined using docs/THRESHOLDS.md
    methodology after first sandbox runs and grid sweep analysis.

    Current placeholder thresholds are conservative defaults for initial testing.
    Follow THRESHOLDS.md 3-step optimization after validating pipeline operation.
