The best ECN broker is a heavily regulated broker, as it is a trustworthy one. FBS is an entirely legitimate broker regulated by the International Financial Services Commission, license IFSC/000102/124. The main benefits of the ECN account at FBS are the fastest market execution, low spreads (from -1 pip), best quotes with no delay, and a large number of liquidity providers. FBS does not make a profit on spread difference and only charges a commission of $6 per lot instead.
