A file containing the MQ4 extension is a MetaQuotes Language 4 file containing source code. An MQ4 file has functions, comments, and variables related to the MQL4 programming language. You can open MQ4 files with MetaQuotes on MetaTrader 4. Since these files are associated with version “4”, it is highly unlikely to use them on MetaTrader 5. If you have the newer version, you’ll need to download the older MT4 version to download MQ4.
Besides MetaTrader 4, you can also open an MQ4 file using text editors like Notepad. However, it is necessary to note that using these editors is not the best approach because MetaTrader is specifically built for this file and displays their information correctly. Follow the steps below to open your MQ4 file.
To open your MQ4 file, you need to install the correct program on your desktop or device. You can begin by installing programs you know as the most commonly associated with these files. The main software program used to open the MQL4 file is MetaTrader Indicator. It is better to download the programs from legit developers’ websites because it is more risk-averse.
As long as you understand the kind of file you are using, you’ll have better luck opening it. Usually, MQ4 are Data Files, so search for an opener program that opens such files on your device and see whether it will actually open the file.
If you are unsure about this, you can find the information in the actual MQ4 file. Follow these steps to discover this information from your computer:
If you are still struggling to open the MQ4 file, a software developer is capable of providing a solution. Contact the software’s developer if you know the program you should use when opening the MQ4 file. If you are clueless, search for a list of commonly used programs online, then contact the developer.
If unable to open your MQ4 file using any of the previous steps, consider using a universal file viewer. This might will probably help you to open the file. Universal file viewers are used for opening different files based on the format. Keep in mind that some files are still incompatible and will open in binary format.
Using these tips above, you should have a relatively seamless experience opening your MQ4 file. If your file still refuses to open with MetaTrader 4, there is a good chance that you are misreading this file extension. This mistake is pretty common considering that many file extensions are spelled similarly to MQ4, although they are completely unrelated to MetaTrader.
