In this fast moving market where market makers are changing there spreads every few seconds and an order instead of being fill is move into an open order status leaves a trader vulnerable before the trader can cancel the order. A fill or kill order is what is needed but I doubt that ever going to happen so I will skip these. I also notice that market maker seem to be pulling out there prices of these options with 30 seconds to go before expiration.
