Metatrader 4 DEMO problem, won't execute buy/sell stops

Hello, so i have been trading with Metatrader 4 on a demo account and everytime i put out a buy/sell stop order it doesn’t get triggered. Basically it just moves to “Account History”.
I have tried Oanda,FX Pro, Alpari(new one) so far and i have the same problem, so does a friend of mine.
Shouldn’t it be possible to put orders like that on a demo account?
