[Visual Basic]
Overloads Public Shared Function RateOfChange( _
   ByVal sc As SeriesCollection, _
   ByVal numberDays As Integer _
) As SeriesCollection

[C#]
public static SeriesCollection RateOfChange( 
   SeriesCollection sc,
   int numberDays
);

Parameters

sc: A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.
numberDays: The number of days before to which the closing price is compared.

Return Type

A series where the first term is the rate of change for the most recent period, the second term is the rate of change for the previous period and so on.

Exceptions

Exception	Description
ArgumentException	Thrown if either parameter is strictly negative.

Remarks

The (n-day) rate of change (ROC) is just the last closing price divided by the closing price n-days ago.

As with the case with the momentum indicator the rate of change (ROC) indicator on extended values and/or turning points indicates oversold or over brought conditions (respectively).
