DECODEFX ACCOUNT GUIDE

How to log in to DecodeFX

The official DecodeFX login page is secure.decodefx.com, the client portal that uses your email address. MT4/MT5 are a separate entry point that uses the details in your confirmation email. Mixing them up is the usual reason a login fails. Conditions here are those DecodeFX publishes for clients resident in Japan and may differ in your country.

What to check if you cannot log in
