I am browsing the forum and I notice that different people post various indicators that are to be used for MT4 applications. However, whenever I attempt to open the file provided, I can only view one of them. The file size is the same size shown in the link, but there is just one file and I am starting to get the idea that there should be two. One is .mq4 and the other is .ex4. Is this correct? I just need to know if it is my computer or if the links are only supposed to be 1 file which are somehow supposed to be broken up into the two filetypes I just mentioned.
mq4 is the human readable code. ex4 is the machine readable compiled version. Often a software developer will allow you to have the ex4 but not the mq4 because they don’t want you to know how the program is written.
