A Pt3 shows lower / lowest volume, on its fractal. If your fractal is higher and includes faster fractal channels, a Pt3 on your fractal may coincide with an FTT on the next faster fractal, which usually means higher volume on that fractal. This is more pronounced when your dominant channle is a retrace of the next slower fractal. I hope I don't sound confusing ...
