Make sure on other computer, you load the compiled release version, and not the debug version.

I'm using VS2008 Express. There should be a tab at the top of your VS compiler that allows you to select between debug and release. Select release and compile. The compiler will give you a file path where your release dll is stored. Follow the file path, and copy the dll to C:\WINDOWS\system32.

That should work.

Hello Mistigri, thanks for the insight.

I'm testing with strategy tester my EA and i also wonder why the result with DLL and the original logic (without DLL) is different..

do you had similiar experience

 

You mean like when calculating an Indicator?

Then yes, for example I wrote my own ATR function in a dll and what happens is that my DLL ATR uses wilder's smoothing while MT4 just uses a simple average ... Same with any of the indicators written by wilders and other indicators who seem to have multiple versions ...

I would first make sure your indicators give the same results as the MT4 platform from the DLL ...
