Yesterday during that big drop at the close IB flashed a message Insufficient funds or something like that, it had to do with a withdraw I made yesterday. I figured I had enough cash to cushion any big drop. Well they closed all open positions for an $1100.00 dollar deficit. I could have sold some shares and brought things back inline. But before I could calculate how much I need to liquidate they closed all my open positions. GREAT WAY TO RING UP COMMISSSIONS YOU CHEEP PUNKS!
