In order for the fail-safe feature to operate, your external funding account will need to be verified with Wedbush Next.

New accounts, accounts undergoing a funding account change, or accounts experiencing a connection error may not be in a verified status. Please be sure to monitor your deposits into Wedbush Next, and make sure there are enough funds in your external account to cover those transfers, to avoid the possibility of an overdraft.

Accounts will be verified automatically after a few transactions to or from Wedbush Next are recognized by our system, so there's no need to do anything on your end.
