Is a momentum indicator.

Was developed by Stephen J. Klinger.

Is computed using the high, low, and close prices, and volume.

Returns two time series. The first is the difference between 34- and 55-period exponential moving averages of volume force. The second is a 13-period simple moving average of the first.

FinancialIndicator["KlingerOscillator",n₁,n₂] uses periods n₁ and n₂.
