You can see my windows version.hmm... I would like to use Win XP, but my VPS uses Win Server. Isn't possible to compile your dll with Windows server?
Thank you Barnix.
Same problem with Windows XP
Hi Barna.
I've tried in my job computers with Win XP and I had the same problem:

First versions
I don't whant to bore you, but just to say one more thing: the first versions of this EAs that you share didn't have this problems.
Regards.
To save you the pain . I went through the same thing but i quickly figured out . Here is the reason why
When you run a Backtest . Win XP does not release the Memory immediately therefore if you happen to run again immediately it will crash the MT4 terminal when it reaches 2 Gigs of Memory usage . Because you have i think 1 GB of RAM it will crash once it hits 1 gig . To see what i am talking about . Open up Task Manager and then sort the processes from Highest usage to Lowest. and then start your MT4 client and do Backtest.
The Maximum memory Limit for MT4 Application is 2 Gigs i.e if the Memory Usage for MT4 Application reaches 2 Gigs it will crash the MT4 application only
If you have less than 2 GB Memory for your Laptop or PC then the MT4 app will crash before the 2 Gig mark because it does not have enough
memory.
The reason i noticed quickly was because i have 12 Gigs of DDR3 on a Windows 64-Bit Vista System with Quad Intel Processors but it still did crash. So it was not Lack of memory but the limitation of MT4 Application i.e ( Most Windows 32-Bit Application like MT4 still have a 2 Gig of RAM Limit ).
Now i am able to do a BACKTEST but i have to watch the Memory usage and i don't run one back test immediately after another to avoid this.

But, for me this is still strange. Maybe I didn't understood right... I guess you are saying that is a memory limitation, but barnix computer have 256Mb and is working well. Also, I'm trying to make a Forwardtest instead Backtest. Have you a sugestion for this situation?
So long as the EA does not use more than 2 Gigs or Less , if you have less memory than 2 Gigs then you fine. If you look at the Task Manager and you see the Memory Usage for that task which will be something like "terminal.exe". if it keeps rising when the EA does calculation at one minute intervals (M1) and does not stablize then let it run until it reaches your Max memory it will crash whether it is Forward test or backtest. I am not sure if you can run it with 256 MB of RAM unless you are using RAMDISK or Linux OS which does good memory management compared to Windows XP otherwise it is going to Drag or slow down that Machine
I do run both Forward and Backtest and i have seen it happen. I am now looking into whether it has something to do with MT4 Build 220. i will update if i find something.
My 2 cents
thanks
Simple dll example
