Full Definition of Percentage Volume Oscillator

The Percentage Volume Oscillator (PVO) provides an indication of whether volume for a given stock is increasing or decreasing.

Percentage Volume Oscillator Calculation

The Percentage Volume Oscillator is calculated by expressing the difference between fast and slow Exponential Moving Averages of volume as a percentage. The PVO requires three inputs, one for each of the fast, slow, and PVO (signal line) moving averages, respectively. A signal line (moving average of the PVO) is superimposed upon the plot and a histogram shows the difference between the PVO and the signal line.

Application of Percentage Volume Oscillator

Increasing volume is detected when the Percentage Volume Oscillator fluctuates around the zero line with increasing oscillator values. Decreasing volume is determined when the PVO fluctuates around the zero line with decreasing oscillator values.

The Price Volume Oscillator tends to fluctuate around the zero line. Increasing oscillator values indicate increasing volume and decreasing values indicating decreasing volume.
