I only have a demo account with them for now for the charts. Their spreads are about the same as forex.com and fxcm so no compelling reason to move yet. I really like mb trading's 1-2 pips spreads for scalping when i come back from work.
The only thing I like about Forex.com is that they pay you interest even with 200:1 leverage. I get 1.3ish pips interest when I short the USD/CHF. I am on a high roll account. Just tell them you want high rolls.
As for FXCM I am with them for their intraday analysis long short ratio's. It seems that different companies have difference tools that are useful.
So in the immediate future I just might open an MB trading or Currenex account for scalping.
