You need a separate registration on FX Blue for each broker account. (One broker account = one FX Blue account. You cannot view or combine multiple broker accounts under a single FX Blue account.)
You can register any number of times from the same email address (and using the same password). You may find it easiest to use your broker account number as your FX Blue user name.
You can then view all your accounts together by setting up a portfolio, or by using our desktop Account Monitor software, or by using the Dashboard in the Connect area of the site.
