Quote from sosa1974:
Brut, its a combination of things actually. When pit noise picks up it can go either way, so its no gospel. I was actually taking a nap when I heard volume pick up. Then the magic words "paper to sell" I looked at my time and sales and it was painting blood red. Yes the louder the better normally ( as long as you are on the right side of it) After the bell I heard reports there were rumors on the Floor that Fed may rate 50 basis points in June. This most likely caused the action we saw to happen so suddenly. I've been trading for 2.5 years. Its all come together in the last year or so. It was no easy task though. Good luck.
