PPO

This method calculates the Percentage Price Oscillator.

var PPO(fastPeriod, slowPeriod, maType, dataArray, calculatedDataArray);

fastPeriod

Fast period integer value.

slowPeriod

Slow period integer value.

maType

One of the Moving Average constants, defined here.

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 PPO method.

function calculate(beginIndex, endIndex)

{

var fastPeriod = 15;

var slowPeriod = 5;

var maType = TechnicalAnalysis.MA_EMA;

var dataArray = new Array();

//populate data array...

...

var calculatedDataArray = new Array();

var rc = TechnicalAnalysis.PPO(fastPeriod, slowPeriod, maType, dataArray, calculatedDataArray);

}
