Note

Parameter Optimization Tip: Start with standard settings and use Reversion’s backtester to measure signal quality. Optimize per asset and timeframe — what works for BTC daily may not work for ETH 4H. Check the indicator usefulness score in algo metrics to verify EFI is contributing to your strategy.
