Today I entered an order to sell. I already owned the stock so not shorting. The TWS showed green. But my balance did not decrease. I pressed the cancel button and the screen showed magenta. I waited, checked the account management screen, for executed trades it was showing nothing. When I queried IB they say that my account shows no trades for today. The audit trail shows the orders but with zero volume? Has this happened to anyone else. Man but this is really weird.
