The Bottom Line

Among the leading FCA-regulated forex brokers in the UK, the majority are actually based abroad. In many cases, this means that they are also regulated by other bodies, such as the National Futures Association (NFA) in the United States. While the retail forex industry continues to develop and improve, traders must remain vigilant in scrutinizing where they place their funds for investment.
