Fxcm oanda ib etc are no liquidity providers. They are stp brokers (in best case) cooperating with the LP mentioned above in the pictures (usually cooperate with all of them but minimum 3 LP).
Sidenote:
Very interesting is XTX Markets and its quick rise. As they are by no means a bank at all it is interesting to see how well they compete with major system relevant banks.
(XTX is a FinTech company only 4 (FOUR!) years old)
Seem outline is that Liquidity Providers(banks) -> Forex brokers(FXCM, OANDA, IB, eg.)
Do you know what’s the rank for forex trading volume among Forex brokers(FXCM, OANDA, IB, eg.)
At least it’s good to know with which help you are actually able to provide and take all that Forex activities anyway and I am glad to see here stable and well known names for all the banks, I dealed with them on other business and all was just fine.
