I'm not from the Jim Cramer crowd and it doesn't sound like you are either. If you are sending orders at the best bid/offer and you can't get filled it's probably because you're too slow. I suppose you could send a marketable limit order in at a price deeper in the book and let the exchange match it at the best price available, but that's still different from outright market (i.e. no limit) orders.
