The reason Oanda has over $150MM in capital and keeps growing while the competition is either declining or flat is because they act like an ECN in that they post their fx rates online The only other brokers that do this are: Dukascopy MB Trading DBFX If FXCM started this practice, traders would have evidence of price manipulation if any and would gain public confidence Until then, trade with Oanda or Dukascopy (preferred since they offer 100X leverage)
