That's as maybe, but FX Open is being investigated by CFTC for its record keeping, taking steps to protect investors funds and methods used to solicit business (along with a group of othe brokers it must be said).
It is a sizable
broker 
so should survive but maybe not in its present form. It may close its US base and just operate overseas or end up merging into another established brokerage. At this stage it may be best to watch this space.
