Price Volume Trend — a running total of each bar's percentage price change
weighted by the volume behind it.
The distinction from On-Balance Volume is the weighting: OBV adds the whole
bar's volume on any up close, so a 0.1 percent drift and a 5 percent gap
count the same. PVT scales the contribution by how far price actually moved.
