PRACTICAL GUIDE
What traders should know
Choose the historical model
Open View → Strategy Tester, select the Expert Advisor and symbol, and choose the test period. For robots sensitive to intrabar prices, consider Every tick based on real ticks where broker data is available. Check the report for data gaps; generated ticks and real ticks are different inputs.
Account for costs and execution
Review symbol specifications, spread, commission and swap assumptions, and available execution-delay settings. Historical tests simulate execution; they cannot reproduce every rejected request or live fill.
Read equity alongside closed profit
Inspect equity drawdown, open basket losses, trade count, profit factor and the worst loss. A profitable balance curve can still hide substantial floating exposure. Compare net results after costs.
Keep an unseen evaluation period
Choose settings using one period, then evaluate on a separate period that was not used to tune them. Changing settings after seeing this result means the period is no longer unseen. Follow with a demo test on the intended broker.
Check the journal and retain evidence
Inspect tester logs for invalid stops, missing history, licensing errors and rejected orders. Save reports and settings for each run. Investigate differences before treating a higher return as an improvement.
