First off... my first week day-trading... so I am learning... so be nice 
One question is... today I was looking to go long at the bid.... I see the level 2 quote and there are about 10k other bids there... So I punch my hotkeys and as soon as I hit enter, I got filled... The bid/ask prices stayed the same and no large orders printed in T/S.. The L2 quotes are still the same so it seems the line hasn't changed... I checked my execution and I was filled at the bid for my buy order so I am unclear why I was filled right away instead of having to wait for the other people that were there before me.... Any ideas why? Thanks everyone
