    I notice that I ususally don't get filled at the bid unless the price moves down to a lower bid in most cases. So at a bid, which orders get filled first? How are Nasdaq and listed stocks different in this regard?
    I also notice that if I post a higher bid, almost instantaneously other bid orders also come in - machines at work? - no trader can be that fast.
