Share Writing Into a File

New comment

I have this project in which I need to execute two trades instantly among two different brokers. I use the native MQL4 function such as FileOpen and FileWrite to communicate the orders between brokers.

What I had an issue with is that some orders will not write to the file if it was previously opened without OrderClose() being called.

This is causing a lot of frustration to me for a month now. Can someone advise me on the best practices for share writing within mql4 environment. 

This is my code for writing:


   int handle;

   //This is for writing

   handle = FileOpen("filename.txt", FILE_READ|FILE_WRITE|FILE_TXT|FILE_COMMON|FILE_SHARE_READ|FILE_SHARE_WRITE);

   if(handle != INVALID_HANDLE){

      FileSeek(handle, 0, SEEK_END);

      FileWrite(handle, body);

      FileCloandle);

      Print("File created.");         

   }else{

      Print("Failed to create file" + GetLastError());   

   }


This is for reading:


   string text = NULL;

   int handle = FileOpen("filename.txt", FILE_READ|FILE_TXT|FILE_COMMON|FILE_SHARE_READ|FILE_SHARE_WRITE);

   if(handle != INVALID_HANDLE){

      text = FileReadString(handle, 0);

   }   

   FileClose(handle);

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?

Next time, post in the correct place. The moderators will likely move this thread there soon.
