10.30 Price and Volume Trend

Price and Volume Trend (PVT) is a running total of daily volume, with each day’s volume added or subtracted according to the percentage change in the today’s closing price over yesterday’s.

                         close[today] - close[yesterday]
PVT = PVTprev + volume * -------------------------------

The starting point (ie. the zero point) for the running total is arbitrary. In Chart it’s merely the segment of data first displayed.

PVT is similar to On-balance volume (see On-Balance Volume), but accumulating a portion of the volume. And see also Accumulation/Distribution, which also accumulates volume.
