Percentage Volume Oscillator (PVO)

The Percentage Volume Oscillator is a simple oscillator view of the rate of change between two converging / diverging exponential moving averages of Volume. [Discuss] 💬

chart for Percentage Volume Oscillator (PVO)

// C# usage syntax
IEnumerable<PvoResult> results =
  quotes.GetPvo(fastPeriods, slowPeriods, signalPeriods);


fastPeriods int - Number of periods (F) for the faster moving average. Must be greater than 0. Default is 12.

slowPeriods int - Number of periods (S) for the slower moving average. Must be greater than fastPeriods. Default is 26.

signalPeriods int - Number of periods (P) for the moving average of PVO. Must be greater than or equal to 0. Default is 9.

Historical quotes requirements

You must have at least 2×(S+P) or S+P+100 worth of quotes, whichever is more, to cover the convergence periods. Since this uses a smoothing technique, we recommend you use at least S+P+250 data points prior to the intended usage date for better precision.

quotes is a collection of generic TQuote historical price quotes. It should have a consistent frequency (day, hour, minute, etc). See the Guide for more information.



Convergence warning: The first S+P+250 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.


Date DateTime - Date from evaluated TQuote

Pvo double - Normalized difference between two Volume moving averages

Signal double - Moving average of the Pvo line

Histogram double - Gap between of the Pvo and Signal line


See Utilities and helpers for more information.


Results can be further processed on Pvo with additional chain-enabled indicators.

// example
var results = quotes

This indicator must be generated from quotes and cannot be generated from results of another chain-enabled indicator or method.
