To Nazar..
The original FXCM website is fxcm.com, while interbankpro.com and forexbrokerpro.id are agents, representatives or IBs of FXCM in Indonesia.
Introducing Broker (IB) is a representative of the broker. It can also be called a broker agent, or a broker's Marketing/Marketer. The function of an IB is as an official representative of the central broker. IBs are tasked with helping investors who experience difficulties related to how to invest and other things related to the investment world.
Registering directly or through an IB is not a problem. Personally, I prefer to register directly. If you register through an IB, that is also not a problem. Through an IB it is only to make it easier to avoid difficulties in opening or knowing broker rules, especially if you have limitations in foreign languages (English).
So actually, interbankpro.com and forexbrokerpro.id are both FXCM IBs in Indonesia.
