ROCP

This method calculates the Rate of Change Percentage.

ROCP(period, dataArray, calculatedDataArray);

period

Period integer value.

dataArray

Array object filled with any data which will be used as the source for calculation.

calculatedDataArray

Empty Array object that will be filled with calculated data.

Returns true if calculation was completed successfully, or false otherwise.

The following example demonstrates how to use ROCP method.

function calculate(beginIndex, endIndex)

{

var period = 15;

var dataArray = new Array();

//populate data array...

...

var calculatedDataArray = new Array();

var rc = TechnicalAnalysis.ROCP(period, dataArray, calculatedDataArray);

}
