MT4 - Trade is disabled [error]?

At the moment it’s impossible for me to place a new order.
It keeps saying: “[B]Trade is disabled[/B]”

and below the OK button it says: “[I]Please verify operation parameters and try again later[/I]”

What do I have to do to fix this?

-it a demo account
-I just added 2 custom indicators (don’t know if it worked before that, but it did work 2 days ago)

It’s because it’s Saturday of course.

Now I feel like a real newbie :stuck_out_tongue:

Not true, I’ve the same issue and have no idea how to fix it
