Price Momentum Oscillator (PMO)

Created by Carl Swenlin, the DecisionPoint Price Momentum Oscillator is double-smoothed momentum indicator based on Rate of Change (ROC). [Discuss] 💬

chart for Price Momentum Oscillator (PMO)

// C# usage syntax
IEnumerable<PmoResult> results =
  quotes.GetPmo(timePeriods, smoothPeriods, signalPeriods);


timePeriods int - Number of periods (T) for ROC EMA smoothing. Must be greater than 1. Default is 35.

smoothPeriods int - Number of periods (S) for PMO EMA smoothing. Must be greater than 0. Default is 20.

signalPeriods int - Number of periods (G) for Signal line EMA. Must be greater than 0. Default is 10.

Historical quotes requirements

You must have at least N periods of quotes, where N is the greater of T+S,2×T, or T+100 to cover the convergence periods. Since this uses multiple smoothing operations, we recommend you use at least N+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 T+S+250 periods will have decreasing magnitude, convergence-related precision errors that can be as high as ~5% deviation in indicator values for earlier periods.
