All MetaTrader 4/5 have a common folder path for a same pc. You can get this folder path with this function below. 

string common_path = TerminalInfoString(TERMINAL_COMMONDATA_PATH);

In this folder you can save a txt file from your program with any info like Equity/Balance. Then read this file from your other terminal with a program. That way you can transfer any info from one terminal to another.

OO MY GOD. i really surprised by your answer . i didnt even know that there is a common folder in metatrader .\

but the problem here is  i use a command of open file to create and write like this

int file_handle = FileOpen("target.txt", FILE_WRITE, FILE_TXT);

but this command create the txt file in metatraders A  special file directory . and i dont know how to navigate the common file directon , because it wont exit from its own file folder anyway .

could you please write the command of writing a text file in common folder plase
