Does it say they get paid for the volume of transactions as Jason says or paid some comission off of causing trader losses? I think that is what he is saying is that FXCM does not gain by causing you a loss, if the Market Makers they contract manipulate the price to cause you a loss FXCM does not profit from it. They do, but not FXCM. So what can we do? Nothing except trade and hope for the best.
There are 10+ banks quoting prices on FXCM's platform. Out of the 10 separate bid and ask prices being quoted by those banks, the best bid/ask is streamed onto the platform. No one bank can control or manipulate pricing since the quotes reflect the best bid/ask out of all the prices. I could understand there being a concern if there were only one market maker on the platform taking all trades.
No one market maker can control pricing, spreads, or execution on NDD execution since there is competition from multiple market makers. It ensures a transparent, anonymous, and fair trading environment.
