If an include file has errors saying that a variable is not defined, but it is defined in the mq4 file that #includes it, will the script or indicator still operate properly?...
I use the #include statement in an MQ4 file to #include an mqh file. When I compile it, there is no error. I then go the the mqh file and put in an obvious error, but don't compile it. I then go back to the MQ4 file and compile it again and there is no error. That tells me that the compiler...

I need to run MT4 in Linux OS, I know this can be done through a software called WINE which allows to emulate windows' software. However, I also need to know if MT4 can be run in some sort of "batch mode", I mean, like a command line (e.g. terminal.exe -optimize) and execute optimizations from...
Hi all, recently I've developed a EA in MT5 and would like to transfer the transactions done in MT5 to MT4 through a set of programs offered in https://www.mql5.com/en/articles/189. It composes of 2 programs, one each in MT5 and MT4. The bug that I have found was in the program in MT4 so I would...
When I compile my code I get an error that says "ErrorDescription": function is not defined. I used it in my code to place buy and sell orders and I forgot to put the preprocessor #include<stdlib.mqh> which is the library that has the defined ErrorDescription() function. But for some reason when I...
