Option Trader,
This was not IB's fault. The failure to act timely was on the part of the NYSE specialist. This was the specialist's fault, and also your own fault because you don't understand how NYSE works. Bitstream was correct when he said that what you experienced is normal and routine for requests to cancel NYSE orders. The NYSE won't bust your trade, because this type of delay is considered normal by NYSE.
It is quite possible that your order had already been filled prior to your cancel request. If so, then you didn't know this, because the fill had not yet been confirmed by the time you requested to cancel. Manual NYSE trade confirms are SLOW. It is also possible that your order had not been filled prior to the cancel request, but because NYSE trading is not fully automated, NYSE specialists are allowed substantial leeway to fill an order for some time after you request to cancel it, because they can always claim to be too busy matching orders manually, so that they didn't have time to act on your cancel request. Manual NYSE order cancels are SLOW.
