Programs to open MQ4 file
Remember to download programs supporting MQ4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of MetaTrader with MQ4 files
If, despite the installed application, the MQ4 file does not start in the MetaTrader application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MQ4 file with the MetaTrader application.
Step 3. Update MetaTrader to the latest version
If, however, after binding MetaTrader with MetaTrader Custom Indicator there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the MetaQuotes Software Corp. website and install the latest version.
Step 4. Check for the following problems with the MQ4 file
The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. Usually this applies to MQ4 files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
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. However, it is important to scan the entire system, not only the file MQ4 or the program directory. Sometimes virus-infected MQ4 files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the MQ4 files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MQ4 file corruption. The easiest way to restore the file is from a backup or by contacting MetaQuotes Software, but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MQ4 files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the MQ4 file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file MQ4 to close. Some anti-virus or backup software may occupy the MQ4 file for a certain period of time. If the problem persists, restart the machine.
