Query: Good basic lesson in reading NASDAQ Level II

The first 10 minutes or so and the last 5 minutes are not worth much. However, the middle portion of this 104 minute VHS tape, is a good introduction to intrepreting NASDAQ Level II displays. Much better than some trading coaches and other pattern/active/day traders can provide. Good companion to Jea Yu's tape.
