What document should I offer to open an account on ParFX?

We strongly advise you against engaging with ParFX. Odds favor that it is an impersonation scam as it seems to be misusing the regulatory information of a legitimate company to pose as an authorized trading platform and deceive investors.

On ParFX's website, it claims to be operated by a company called Tradition Financial Services Limited in the UK. While our search indeed located corresponding information about this company, it is crucial to note that the details including the website address listed on the website of the Financial Conduct Authority (FCA), the UK financial regulator, are inconsistent with ParFX. Furthermore, this FCA-authorized entity is not allowed to accept retail forex customers.

Therefore, ParFX appears to be a scam. By trading with this platform, traders may expose themselves to fraud and identity theft, which could be financially and personally devastating. To mitigate such risks, it is recommended to choose fully regulated brokers only.
