DARBES,
what do we need to signal a volume reversal ?
You know. You should know. Tell us.
At any given time there are many "technical" signals that may occur. Some contradictory. The fact that a volume reversal in AMD has happened is something to consider. However, if you believe like I do, that the reason why TA "seems" to work is that it is a self fulfilling phenomenon, then the overriding question is; which TA signal is followed by the most people who can move a stock the most. You guess. Then place your bet.
IMHO
