Top class broker in the world / the most handsome and has many clients, who is it...
@ bang abeng:
There are large brokers widely used by financial institutions, and brokers that are more geared towards retail traders. Among the well-known large brokers are CitiFX Pro and Interactive Brokers, both in the US. For retail brokers that are regulated and well-known, there are IC Markets, Exness, FXOpen, etc.
To my knowledge, there is no class division for forex brokers (class one, class two, etc.). In Indonesia, the more famous ones are usually retail brokers.
