int OnInit(){ int filePtr = FileOpen("FileOutput.txt", FILE_CVS|FILE_WRITE); FileWrite(filePtr, 1, 2, 3); FileClose(filePtr); return 0; }
Hope that's clearer.

Sorry, just realised that the file will is opened in a different folder, under the tester folders. Sorry about that. That should help me figure out my other problem.

I did the same thing and I can't find the file.
int OnInit() { if (DealHandlerDevice.IsSetup()==false) DealHandlerDevice.Setup(); CreateInitialPyramid(Symbol()); filehandle=FileOpen("drawdowns.txt",FILE_COMMON||FILE_ANSI||FILE_WRITE); return(0); } //+------------------------------------------------------------------+ //| Expert tick function | //+------------------------------------------------------------------+ void OnTick() { double p=GlobalPips(); p=GlobalPips(); if (p<drawdown) drawdown=p; if (p>=Target) { FileWrite(filehandle,drawdown); //Print("Profit ",p," > target ",Target); CloseAll(); CreateInitialPyramid(Symbol()); drawdown=9999999999.99; } } //+------------------------------------------------------------------+ //| Expert deinitialization function | //+------------------------------------------------------------------+ void OnDeinit(const int reason) { FileClose(filehandle); }
If the backtest is stopped before end, files are not written?

Also (offtopic) : Why, if backtest is stopped before end, there is no Results tab?
We don't know the reason of interrupt. Therefore, agent should be stopped immediately and quickly

No, I meant, If I stop it by clicking on Stop, I should see the Results tab containing what was done until that moment.
File issue solved: it cannot make the file if operators are || . Must be only bitwise ( | ).

We'll think about it.

Hi,
Not sure if this is a bug, or if I'm just trying to do something that is not possible. Below is a very simple EA code, to run on the tester to see if I can use the file output.
int OnInit(){
int filePtr = FileOpen("FileOutput.txt", FILE_CVS|FILE_WRITE);
FileWrite(filePtr, 1, 2, 3);
FileClose(filePtr);
return 0;
}
When run in a demo account, this works fine, but when I run it in the tester, the file is not even produced. Is file I/O even possible when using the tester?
Regards,
Steven
