Percentage Volume Oscillator

The Percentage Volume Oscillator (PVO) shows the percentage difference between two moving averages of volume. This study takes three different periods. The first two define the two moving averages that are being compared. The last period is used to smooth the difference and form the signal line. A histogram of their difference (PVO minus signal) is also given. The user may change the inputs (EMA, SMA) and period lengths. This indicator’s definition is further expressed in the condensed code given in the calculation below.

Calculation

//method1 = moving average (ma), user defined, default is EMA
//method2 = moving average (ma), user defined, default is SMA
//period1 = user defined, default is 12
//period2 = user defined, default is 26
//signalPeriod = user defined, default is 9
//index = current bar number

MA1 = ma(method1, index, period1, VOLUME);
MA2 = ma(method1, index, period2, VOLUME);
Plot1: PVO = ((MA1 - MA2)/MA2) * 100;
//Calculate moving average of PVO (signal line)
Plot2: signal = ma(method2, index, signalPeriod, PVO);
PlotHist3: hist = PVO - signal;
