Volume Rate of Change (VROC)
The Volume Rate of Change (VROC) is almost exactly the same as the ROC indicator, with the exception that instead of price data, volume data (VOL) is used. A smoothing component is also applied.
VROC(int period, int smooth)
VROC(IDataSeries inSeries, int period, int smooth)
VROC(int period, int smooth)[int barsAgo]
VROC(IDataSeries inSeries, int period, int smooth)[int barsAgo]
double
When using this method with an index (e.g. VROC(14,3)[int barsAgo] ), the value of the indicator will be issued for the referenced bar.
inSeries Input data series for the indicator
period Number of bars included in the calculations
smooth Number of Bars included in the calculation for the smoothing
//Output of the current value for the Volume ROC
Print("The current value for the Volume ROC is: " + VROC(14, 3)[0]);
