FAQ FxPro Markets

Why can I log into FxPro Markets with my FxPro Direct credentials, but not with my MT4 or cTrader login?

FxPro Markets is a proprietary trading platform designed for clients of FxPro. As such, it is compatible with your login credentials from FxPro Direct, which uses the same login format (user email and password).

MT4 and cTrader are separate trading platforms, not associated with FxPro Markets. Both platforms use different login methods (numerical login and password) when compared to FxPro Direct, and as such, you cannot use these credentials to access FxPro Markets.
