I got a 'trade bust' on March 08 Sugar. I placed a limit at 10.28, it opened at this price. Then IB sent back a message saying the trade was "busted" , it was the action of the exchange NYBOT because the price was "out of range", and trades at this price are cancelled. This occurred Friday before last (the 27th), It's still quoted at the exchange as opening at this 10.28 price though. I couldn't get any information about this from NYBOT. Has anyone experienced this before or have any comments?
