Do they have UK license?

Regarding your inquiry, we searched the register of Financial Conduct Authority (FCA) and confirmed that goldfx is not licensed in the UK. Furthermore, the regulatory information provided by goldfx cannot support its legitimacy in forex trading. As such, we strongly suggest investors steer clear of goldfx.

While it claims to be operated by Olympic Markets LLC which is registered with the Financial Conduct Authority of St. Vincent and the Grenadines (SVG FSA) and we did find a company of that name in the SVG FSA registry, it is critical to note that the offshore financial watchdog has explicitly stated that entities engaging in forex trading and brokerage are not licensed from this jurisdiction. Consequently, goldfx remains unsupervised.

Furthermore, according goldfx's claim, we also found the Olympic Markets Ltd. in the Labuan Financial Services Authority (LFSA) register. However, goldfx and Olympic Markets Ltd have different addresses, phone numbers and domains. Such a great discrepancy raises suspicous about goldfx's authenticity and legitimacy. There is a possibility that goldfx copies details of Olympic Markets Ltd to appear legal.

In conclusion, dealing with goldfx is highly risky, and investors may suffer financial losses and identity theft, as there are no rules in place to safeguard them. Therefore, we strongly suggest investors stay away from unlicensed brokers like goldfx and instead choose a fully regulated one.
