If someone likes to do a lot of scalping intraday they may find "patterns" from the wall activity that may be benificial for them to time entries or exits. As far as ACV ratio goes, if you start hitting at least a 2:1 ratio on the DOM, you are looking for price to trade to the side with size (not away from it).
No secret....it is all mentioned in the ACV scalping thread that was started by VSTscalper. http://www.elitetrader.com/vb/showthread.php?s=&threadid=68098&highlight=acv
thank you. Didnt I read on another site that you are ex US special forces and a navy pilot and now a hedge fund manager.
Nope....manage private funds and I used to fly AH-1S Cobra attack helicopters and was a Ranger in the US.Army.
I loved flying since I was a kid so I had a wild hair when I was out of college to fly in the military.....that was good times back in the day.
