Can a broker disable expert advisors?
Can a broker disable expert advisors?
Does IsExpertEnabled() check whether the broker has enabled or disabled expert advisors? Or does it only check whether the user has enabled it in the terminal?
Similarly, does IsTradeAllowed() check whether the broker has enabled or disabled trading in the account, or only check whether the user has enabled trading in the terminal?
If those functions are only for checking the user settings in the terminal, what are the possible ways to check whether the broker has disabled expert advisors or disallowed trading? The only way I can think of is by submitting an order as a test in an expert advisor.

Local function, nothing to do with broker.
I don't think you can check before getting an Error 133.

I think ERR_TRADE_DISABLED means that you cannot trade maually either. So the broker has disabled all trading, not just experts.
So are the functions IsExpertEnabled() and IsTradeAllowed() only checking the user's terminal settings, and not what the broker has allowed?

I believe so, yes.
In my case I was able to trade manually, to close positions but not to open new ones.
So perhaps I am saying that trade can be dissallowed rather than the EA itself being stopped. I seem to recall the broker having software to stop the account trading if an EA seems to have gone crazy and placing too many orders, but I wouldn't know where to find a comment on this or at what point an EA is considered errant.
