file

[st.khalili]

Hello geniuses

I have a code that hedges a some of orders and stores them in a file.

If the robot is removed from the chart, after restarting, the robot can read the hedges from the file, but if for any reason the Meta-trader program is closed, after restarting the robot, it will display all of them as zero. Can anyone guide me???

Is the file still there with valid data once you close, and re-open MetaTrader? Or does it somehow get deleted or overwritten?

It would help if you share the code you use to re-read the file when the EA is re-started

when i closed Metatrader, checked the file and its data are correct, but after reopen it changes and would be 0.00000000

Without debugging I cannot say for sure, but I think you need to debug this section and check you are loading the data as expected:

while(!FileIsEnding(filehandle))
              {
               string cell = FileReadString(filehandle);
               cell= StrToInteger(cell);
               if(cell!=0)
                 {
                  ArrayResize(Pairhedge[row].pairmember, ArraySize(Pairhedge[row].pairmember)+1);
                  Pairhedge[row].pairmember[ArraySize(Pairhedge[row].pairmember)-1] = (cell);
                  if(FileIsLineEnding(filehandle))
                    {
                     col =0;
                     row++;
                    }
                  else
                     col++;
                 }

You are calling the file open/close functions within a loop which struck me as peculiar, unless you are calling different files each time.

It appears to be the same file so it would be better to open once, and close at the end I think

yes its different file each time

Ok - debugging would be the next step
