It's really difficult to say what the problem is, but I guess you are stopped-out (your positions are liquidated, mistakenly called by most traders 'Margin Call'). The Stop-out level at FXDD is 100%, not 5%, 25%, 70% etc. like with other brokers (Alpari, etc.)
To make sure if this is the reason, check the comments and you will have a message like this: so:99%/............./[stopout]
So don't place too big order sizes. The leverage is only 1:200, so can open max. 1.5 lots with 1k.

Wow!!! You have never been stopped-out (had a 'Margin Call') before? Congratulations. It looks to me like you are a beginner trader or trade in an extremely risky way.
100% is of the available Equity (not Balance). Say you have won and your equity is $2000 and leverage 1:200. So you can buy around maximum 3.2 lots of EURUSD. You bought 2 lots and now the price goes against you, so your position(s) are liquidated (Margin Call) one by one.
Almost everybody had this problem and it is described in every FX forum. Just check 'Margin Call' and you will have hundreds of posts about it.
As I said before, 'Stop Out' is not the same as 'Margin Call', but nobody cares.
