         { 
            string file_name= "DATA.csv";
            int file_handle = -1;
            file_handle=FileOpen(file_name,FILE_WRITE|FILE_READ|FILE_CSV|FILE_SHARE_READ|FILE_ACCESS_DATE|FILE_IS_WRITABLE|FILE_IS_READABLE);
            if(file_handle==INVALID_HANDLE)
               Print("Error opening rep-file: "+file_name);
         //---
            FileSeek(file_handle,0,SEEK_END);
            FileWrite(file_handle,TimeToString(iTime(Symbol(),PERIOD_CURRENT,1)),
            DoubleToString(iOpen(Symbol(),PERIOD_CURRENT,1)),DoubleToString(iHigh(Symbol(),PERIOD_CURRENT,1)),DoubleToString(iLow(Symbol(),PERIOD_CURRENT,1)),DoubleToString(iClose(Symbol(),PERIOD_CURRENT,1)));
            FileFlush(file_handle);
            FileClose(file_handle);

Look in the correct place. Live: <data folder>\MQL4\Files. Tester: <data folder>\tester\Files.

I have the same issue

I am having the same problem.

I converted an indicator from MT4 to MT5, when I run it in strategy tester in MT4, the indicator generates a .csv file that is saved in tester\files (in MT4)

In MT5 there is no "files" folder inside the tester folder. But if you load the indicator in a live chart, it saves in MQL5\Files.

Where is the file being saved in MT5 when running in strategy tester?

I discovered the folder path

C:\Users\(Your PC)\AppData\Roaming\MetaQuotes\Tester\ Agent

I have the same problem but for reading in a file rather than writing it out during EA initialization in strategy tester. All works fine when running live but when using the ST file not found.

If I put the file in  C:\Users\(Your PC)\AppData\Roaming\MetaQuotes\Tester\Agent  the first thing the agent does on running is clear the directory of any files so this doesn't resolve my problem unfortunately.

Did anyone find a solution?

If you want to read it upon start-up then use the "Common" area as you never know which agent will be used for the testing. Use the "FILE_COMMON" flag (location of the file in a shared folder for all client terminals \Terminal\Common\Files). Please also read the comment on your original thread as well.
