Try adding the FILE_READ statment to it as in:

int handle = FileOpen( FileName, FILE_CSV | FILE_READ | FILE_WRITE, ";" );

of course, you can use FileOpen(FileName,FILE_CSV|FILE_WRITE,";"); for prewrited file then use related reading syntax such as FileReadArray,FileReadString, ....

 

I believe Period_Converter_Opt.mq4 writes a new line for every time it converts. it runs as ind not scrpt

thank you very much lowphat, the file that you have attached was so usefull, this program, use FileTell Syntax to find pointer position, and then use the FileSeek to Set the pointer position of file, so the new data can be writen right after the last ones
