Can an expert advisor run with a Screensaver on?

I'm trying to find reasons why my EA won't run. I've tried everything.

Only thing left is perhaps it won't make trades while the screensaver is on?

The smiley face is on my MT4, all the right checkboxes are checked. I've backtested it on the same platform with the same broker. ;/

You have to be clear with the terminology. Do you mean screensaver or do you mean hibernation? Screensaver mode does not affect running programs such as MT4 or a virus scan. Hibernation puts the computer and all programs into a suspended state and this would prevent MT4 from executing. I think the default on new computers is screensaver starts after 15 minutes of inactivity and hibernation will happen after 60 minutes.

You make it sound as if the EA never takes a trade, so you need to look at the error log in the Experts and Journal tabs.

No, I run MT4 via Crossover on my Mac, just in screensaver mode no hibernation.

All I get are messages like that over and over, the last message seems to be like it is telling the platform to take a sell order because the minimum cross distance has been reached, yet it doesn't.

By the way it is the Universal Cross MA EA. Just based on two different EMA crosses, then it either sells or buys.

The exact same settings work on the backtest.

Now I got this error:

What does that mean lol.

I think it might be a coding problem. Something is definitely wrong, but the program isn't handling the problem properly, but I'm just guessing.
