Differences between .mq4 and .ex4 files
By default, the MetaTrader 4 provides some standard indicators, but you can add your own by using two different types of files:
From a practical point of view, it does not matter which type of file you have available (usually it is the .ex4 only without an access to the source code) until you would like to make some changes directly in the source code.
Even if you have the .mq4 file available, but you have no coding experience, do not worry! After uploading the file correctly to your MetaTrader 4's root folders, the trading platform will do everything needed for you automatically.
Once you install the .mq4 file and launch the MetaTrader 4, the trading platform immediately creates also the .ex4 executable file, so it will be ready for use like you would install the .ex4 file.
