My account's been labeled as “day trader” and I got a big margin call. What should I do? What trades can I place in the blocked period?
The SEC considers a day trade to be any trade that is opened and closed within the same trading day, and considers a day trader to be any trader that completes 4 or more day trades within 5 business days. If so they would label you day trader and in the US you are required to have at least $25K in your account. Maybe that's why they require you to add more money to your account?
