Notable changes which recently have occurred in the report is the removal of MB Trading when back in November their retail Forex accounts were moved under GAIN Capital though white label of online discount stock broker TradeKing late in 2015, also the removal of RJ O'Brien (which have helped to contribute to the further falling of assets).

The big three in the United States for retail based Forex traders remain: FXCM (NYSE: FXCM), GAIN Capital (NYSE: GCAP) and OANDA.
