1. Play video	Please edit your post. For large amounts of code, attach it.

2. string filename=terminal_data_path+"\\MQL4\\Files\\"+"data.csv"; 

   Use this. Been ask and answered many times.
   

Thanks. I had search for the problem, but didn't a similar problem (specifically open file in a linux env).

 I tried your approach, but I'm still getting the 5004 error. Take a look at my code: 

string filename= "data.csv";

int filehande 

     filehandle=FileOpen(filename,FILE_WRITE|FILE_CSV,";");

             if(filehandle==INVALID_HANDLE)

               {

                   

                Print("Failed to open the file by the absolute path ");

                Print("Error code ",GetLastError());

               } else 

               {

                    Print("file opened with sucess");

               }

     

     

     }
