Lescor, what exactly do you pick up from it?
Heres what I listen to:
1) Pit noise
2) Comments like 'big paper buyer/seller', 'good selling here'
3) Certain MMs holding a level, if its the same one every time it hits a level, then they are not mentioned the next time the level is reached, look for the futures to go through
BTW, I trade NAZ stocks, scalping
