Trading of the big share blocks on L2 look like they are being handed off, whenever i see those milly bids flash, i know the big share sells are coming. although it looks like shares being dumped it doesnt show up specifically as dilution on many of the charts...i know it isnt flipping but the up and down pattern is similar to when people are flipping, kinda interesting trading pattern...Some of the charts indicators (other than pps) should be way down if it was dilution but they barely made a dent...im gonna try to study this, i was in denver all week enjoying so havent got to look into anything yet
