You must choose a forex broker with the top tier of regulation because not all forex broker regulators have been tested and proven responsible. Top-tier regulations mean stricter policies. The institutions that enforce it are usually known for their experiences in sanctioning members that are proven to violate their rules. Some of them even helped with the process of compensation to traders. As such, it is highly recommended to find a broker with top-tier regulation.
Brokerage regulators belonging to this elite class are the NFA/CFTC, BaFIN, FINMA, JSFA, FCA, and ASIC.
