Why can't I use the same email address on my client account that is on my advisor account?


When attempting to create sub accounts for themselves, many advisors cannot complete the process due to the client email address matching that of the advisor.


As a measure of client protection, IBKR will not allow the e-mail address of a client to match that of the Advisor.

A popular option is to create a new e-mail address for yourself, using a free service such as Gmail.

This will allow you to create the new sub account.
