Important Notes​

warning

Realistic Expectations: Backtests show historical performance, NOT guaranteed future results. Always validate with forward testing before risking real capital.

info

Data Quality Matters: Use high-quality historical data from your broker. Poor data quality = unreliable backtest results.

danger

Avoid Over-Optimization: More complex doesn't mean better. Simple, robust strategies typically perform better in live trading than heavily optimized ones.

tip
