Super Fast Trade Execution

I had the fastest fill I have ever had on an options trade today. I mean, I literally pressed the button, flipped over to the order status screen, and read my status "filled". Now besides the sense of foreboding that this made me feel (I mean if the market maker's that willing to jump on a bid it makes me kind of nervous), I have to say that I was pretty impressed with the speed of the fill. I bought 6 contracts of JPM Jan 55 Calls, so we'll see soon if that was a good idea or a bad idea.
