STOCH

This method calculates the Stochastic.

Syntax

var STOCH(fastKPeriod, slowKPeriod, slowKMAType, slowDPeriod, slowDMAType, highPricesArray, lowPricesArray, closePricesArray, calculatedSlowKArray, calculatedSlowDArray);

Parameters

fastKPeriod

Fast K period integer value.

slowKPeriod

Slow K period integer value.

slowKMAType

One of the Moving Average constants for Slow K.

slowDPeriod

Slow D period integer value.

slowDMAType

One of the Moving Average constants for Slow D.

highPricesArray

Array object filled with high prices.

lowPricesArray

Array object filled with low prices.

closePricesArray

Array object filled with close prices.

calculatedSlowKArray

Empty Array object that will be filled with slow K calculated data.

calculatedSlowDArray

Empty Array object that will be filled with slow D calculated data.

Return Value

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

Example

The following example demonstrates how to use STOCH method.

function calculate(beginIndex, endIndex)

{

var fastKPeriod = 15;

var slowKPeriod = 5;

var slowKMAType = TechnicalAnalysis.MA_EMA;

var slowDPeriod = 2;

var slowDMAType = TechnicalAnalysis.MA_SMA;

var highPricesArray = new Array();

var lowPricesArray = new Array();

var closePricesArray = new Array();

//populate arrays..

var calculatedSlowKArray = new Array();

var calculatedSlowDArray = new Array();

var rc = TechnicalAnalysis.STOCH(fastKPeriod, slowKPeriod, slowKMAType, slowDPeriod, slowDMAType,

highPricesArray, lowPricesArray, closePricesArray, calculatedSlowKArray, calculatedSlowDArray);

}
