MT4 and EA: Before Running, Do the Checks First

Verify Symbols and Parameters

Check the symbol name, chart timeframe, parameter version, and trade volume settings used by the EA. Platform symbols may have suffixes, and contract specifications may also differ. When migrating to another account, these conditions need to be reconfirmed.

First Understand What the Program Is Allowed to Do

An MT4 EA can automatically execute trading rules. Before running, you should read the program documentation to confirm the automated trading settings and required permissions. For any external calls or dependencies you do not understand, first verify their purpose with the developer, then decide whether to enable them.

Separate Historical Testing from Runtime Observation

The Strategy Tester can be used to observe program behavior under historical data. Test records should include the data period, modeling method, parameters, and cost assumptions; demo account observation focuses on checking whether orders are executed according to the rules. Neither can prove future live results.

Determine Pause Conditions in Advance

Before running, write down when the program should be paused for inspection, for example consecutive abnormal orders, duplicate orders, connection abnormalities, or positions deviating from settings. Automated execution does not eliminate risk, nor should it be a reason for no human checks.

Keep Logs for Review

Record the program version, parameter adjustment times, trading logs, and reasons for manual intervention. When discrepancies appear, first distinguish between strategy signals, contract conditions, and execution issues, then decide whether to modify the program.
