Disclaimer: I am not sure how these companies fill orders, but I day traded for a few years while in school, and if you are going to try to buy this, make SURE you don't just put in an open order or you will get killed. You have to be able to set a limit price on what you will accept. Sometimes you will not get your order filled, but it sure beats getting filled at, say 215 and have it go down to 160, this is really risky in general trying to chase something this hot, better to try to buy on panic corrections....
