Why can't I use the same email address on my client account that is on my advisor account?
Overview:
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.
Information:
As a measure of client protection, IB will not allow the e-mail address of a client to match that of the Advisor.
What you can do, is create a new e-mail address for yourself, using a free service such as Yahoo!.
This will allow you to create the new sub account.
