They are a good broker i have several account with forex brokers and they are one of them im thinking about closing my other accounts and just using them they don't trade against there clients. there spreads are good. one thing i look for in a broker is s.t.p. or no dealing desk. there's only a few retail broker's i will trade with.
David, If by stp you mean being able to trade with no dealer desk intervention, I'm not sure how you came to the conclusion that FXDD operates in this way. I could be missing something but I've looked over their website and haven't found any mention of stp or absence of a dealer desk.
