If you are using the same MT4 build & the same EA, the different results are like caused by utilising different “MT4 Info” settings (such as spread) when generating your export. This can cause markedly different back-test results depending on which parameters are different.
Thanks for answer.
I use the default settings from Tickstory.
Maybe the problem comes from the EA…… I id’not experience this problem with other EA….. ?!?!
