## Important Notes[​](#important-notes "Direct link to 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

**v4.4.4+ Enhancement**: BananaEA now includes Strategy Tester bypass system for cleaner backtest reports. Debug log filtering ensures clean backtest journals with zero filter alert spam.
