Finding the Logs folder

The first step in finding the log files in MT4 is to locate the Logs folder. There are several ways to access these files but the simplest way is as follows:

Go to the ‘Experts‘ tab on the ‘Terminal’ window. This window can be opened through the ‘View – Terminals’ menu command, by pressing the ‘Ctrl+T’ keys, or by clicking the ‘Terminal’ button on the ‘Standard’ toolbar.
Right-click on the messages displayed in the window and click ‘Open’ to select the desired file.
The files for the experts’ logs are stored in the ‘Logs’ directory, with filenames that correspond to the log date in the format YYYYMMDD.log (the first four digits represent the year, the next two digits represent the month, and the last two digits represent the day. For example, a log file named 20230207.log was generated on February 7th, 2023).

Using log files to improve trading experience

Log files in MT4 provide valuable information that can help diagnose and resolve issues with the platform. By locating and reviewing the log files, traders can get a better understanding of what is happening in the platform and take appropriate action to resolve any problems. This information can help traders be more confident and efficient in their use of MT4.

The importance of Log files for MT4 programmers

In addition to providing information about trades and other actions taken in the platform, log files in MT4 play a critical role in the debugging process for MT4 programmers. When a program is executed in MT4, a log file is generated that contains detailed information about the execution of the program, including any errors that may have occurred.

This information can be used by programmers to identify the source of the problem and to debug the program. For example, if a program is not executing as expected, the log file can be used to identify the line of code that is causing the issue and to diagnose the problem. The log file can also provide information about any data or variables being used in the program, which can be useful in identifying the root cause of the problem.

Conclusion

Log files in MT4 are a valuable tool for both traders and programmers. By locating and reviewing the log files, traders can improve their experience with the platform, and programmers can debug their programs to ensure that they run smoothly.
