Price and Volume trend

The Price and Volume Trend (PVT) is a cumulative total of volume adjusted according to relative changes in closing prices. It is similar to On Balance Volume (OBV).

Overview

PVT is calculated by adding a percentage of the volume when prices close up and subtracting a percentage of volume when the prices close down. (OBV adds all volume when prices close higher and subtracts all volume when prices close lower.) The amount of volume added or subtracted to the PVT is relative to the amount that prices rose or fell compared to the previous day's close (see note on calculation below).

• When the price changes by a small percentage, PVT adds only a small portion of volume to the indicator
• When the price changes by a large percentage. PVT adds a large portion of volume to the indicator
