Thanks guys you've solved it! Feel a little silly for not checking the log/assuming broker was on latest build

'has newer unsupported version, please update your client terminal'

I'm on 1010 from August 18 @ Darwinex and IC Markets - contacting now to see what the story is.

Edit: 1010 is latest build so I guess the error is incorrect and this was compiled on an older unsupported build?

Hi a friend has sent me a Dreema expert .ex4 file over email, I've copied to the Data -> MQL4 -> Experts folders as per usual, it shows up in my navigator but when I drag to a chart nothing happens. I've never experienced this before. I'm on the latest build but I've just tried on an older back testing terminal too and no luck.

What's even stranger is he just forwarded me another email he'd previously sent to a relative and that file works at their end, but when I try, exactly the same story: no properties window, no unhappy face - nada.

Has anyone experienced this before or know the cause/fix?

I've noticed Windows isn't applying the expert icon to the file in explorer either, though has EX4 under type like every other expert in the folder. Any help would be much appreciated.

Cheers.

PS file is exceptionally large too - 280kb - never seen a .ex4 this big before ... is this normal with Dreema?
