I sold 29 shares of KTII at the price 64.89 via exchange ARCA. My order was filled at the time of 12:55:25, Nov10. the order was never shown in the last price column, and I used IB's reqHistorical to download the intraday history with bar size of 1 sec. the order was not there. this stock is very illiquid. just couple of hundreds of shares each day. any one knows what happened.
