i have little problem with this code
OnTick or OnTimer i drop some data to array then
and thats working fine in expert adv. After removing expert from chart i can access my file and get the data i want.
Problem starts when i try to do this in system tester...
I tried to put FileClose() in all places like OnTester, OnDeinit even in some mql5 functions like OnTesterInit ect but when i start system testing i see that my file xxx is created and has 0 bytes but after when testing is done file is still 0 and i cant access to it or delete it so i assume that file is still open by the program and FileClose didnt work...
I have to close MT4 terminal to delete those files....
Any idea ?
