Hi Abe,  I appreciate you pointing these out.  I'm tryin to get the concept of the pocket pivot.

Are you not counting the vol on 2/10 b/c it's 11 days back or because it closed at the top of its range for the day?

Personally, I was only looking at the 11 days back.  However your point that 2/10 was really support is also very interesting. A third point is that 2/28 heavy volume is occuring higher in price than the heavy volume on 2/10.  The heaviest hitters are embracing the uptrend.
