A reliable EA should explain its entry logic, exit logic, risk model, suitable markets, and expected trading frequency. Avoid evaluating an automated strategy from a short profit screenshot alone. Review independent results, drawdown, sample size, and how the strategy behaves during unfavorable conditions.
A practical evaluation framework
Start with a clear objective, use measurable rules, and document the result. Demo-test new tools or changes under conditions that resemble your intended live environment.
Final takeaway
Good tools support a disciplined process; they do not replace one. Keep expectations realistic and protect capital first.
