FAQPage Schema

How do I read MT5 log files to check if my indicator executed correctly?▼

MT5 log files record Print() output, compilation errors, and runtime results. Access today's log at $MQL5_ROOT/Program Files/MetaTrader 5/MQL5/Logs/YYYYMMDD.log—the file is UTF-16LE encoded and tab-separated, readable with grep-like pattern searches to validate indicator execution without opening the Experts pane.

Can I verify unit test results from MT5 logs?▼

Yes. Unit test outputs appear as Print() statements in MT5 logs. Search the log file for test identifiers or assertion results to confirm test success or failure without manual inspection of the terminal.

What information can I extract from MT5 log files?▼

MT5 logs contain Print() output from indicators, scripts, and EAs; compilation error messages; and runtime errors. Pattern-based searches retrieve specific results, allowing you to validate test execution, diagnose crashes, and confirm expected behavior.

Do I need special tools to read MT5 log files, or can I use standard commands?▼

MT5 logs use UTF-16LE encoding and tab-separated format, requiring tools that handle this encoding. Standard read and grep-like bash commands work directly on the log files, making retrieval straightforward without additional converters.

How do I search MT5 logs for specific errors or Print() statements?▼

Use grep-like pattern matching against the log file to filter for error keywords, test identifiers, or specific Print() output. Results are returned without modifying the original file, preserving the log for auditing.

When should I check MT5 logs instead of the Experts pane?▼

Check logs for permanent records of past test runs, batch validation of multiple indicators, and programmatic analysis of results. Logs persist after terminal restart and support automated reporting, unlike the transient Experts pane.
