How to open MQL file?

The most common problem when using MetaTrader Indicator is that a specific MQL is not associated with the program. This causes the file MQL to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MQL file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install MetaTrader

The first step is to check if the computer has the MetaTrader program installed. The easiest method is to use the system search engine by entering the program name MetaTrader in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file MQL.

Programs to open MQL file

Remember to download programs supporting MQL files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of MetaTrader with MQL files

If the application is or has been freshly installed, but the MQL file still does not use the MetaTrader program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the MetaTrader application as the default for handling the MQL file.

Step 3. Update MetaTrader to the latest version

If, however, after binding MetaTrader with MetaTrader Indicator there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the MetaQuotes Software Corp. page and install.

Step 4. Check for the following problems with the MQL file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The MQL file may be unusually small compared to the original file. This is most often caused by a problem while downloading the MQL file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our MQL file. However, remember that not every infected MQL file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the MQL files changes over time. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair MQL file corruption. You can restore the file from a backup or use MetaQuotes Software Corp. help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MQL files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the MQL file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes it is necessary to wait a while before referencing the MQL file again. Some anti-virus or backup software may occupy the MQL file for a certain period of time. If the problem persists, restart the machine.
