Did you just perform a full ACAT transfer to tastyworks from an outside brokerage firm and see some extra cash that didn't make it over? Don't worry! That cash still belongs to you. A cash balance at your old broker can appear when your old account had an outstanding dividend or interest payment. Even after bidding farewell to your old broker, your old account is still linked to your tastyworks account for six months after the transfer to account for any dividend or interest payments. Each broker has their own weekly scheduled interval to sweep the cash into your tastyworks account. So, if you see a remaining cash balance, then don't worry because it's coming your way.
