Stochastic

Stochastic

stochK( kLength, kSmoothing, dLength [, source | sym() | inv()] [, barIndex] )

stochD( kLength, kSmoothing, dLength [, source | sym() | inv()] [, barIndex] )

The Stochastic is designed to indicate when the market is overbought or oversold. It is based on the premise that when a market's price increases, the closing prices tend to move toward the daily highs and, conversely, when a market's price decreases, the closing prices move toward the daily lows. A Stochastic displays two lines, %K and %D. %K is calculated by finding the highest and lowest point in a trading period and then finding where the current close is in relation to that trading range, %K is then smoothed with a moving average. %D is a moving average of %K.

Parameters

To Create a Series

var myStudy1 = null;

var myStudy2 = null;

var bInit = false;

function main() {

var myVar1;

var myVar2;

       if ( bInit == false ) {

               myStudy1 = stochK( 14, 1, 3 );

               myStudy2 = stochD( 14, 1, 3 );

               bInit = true;

       }

       //retrieve the current values

       myVar1 = myStudy1.getValue(0);

       myVar2 = myStudy2.getValue(0);

       return new Array( myVar1, myVar2 );

}

To Retrieve a Single Value

function main() {

       ...

       ...

       myVar = stochD( 14, 3, 5 );

       //do something with the value in myVar

}

Calling Examples

       //create a study that uses IBM as the symbol along with whatever bar

       //interval you are using in the chart where the script is loaded

       myStudy = stochK( 14, 1, 3, sym( "IBM") );

       //create a study that uses the 15-min bar interval, regardless of the bar 

       //interval of the chart in which the script is loaded

       myStudy = stochD( 14, 1, 3, inv(15) );

       //create a study that uses the Daily bar interval, regardless of the bar 

       //interval of the chart in which the script is loaded

       myStudy = stochK( 5, 3, 3, inv("D") );

       //create a study that will be based on MSFT 30-min bars, regardless of

       //the symbol/bar interval of the chart in which the script is loaded

       myStudy = stochK( 14, 2, 5, sym( "MSFT,30" ) );

       //create a study that will be based on the high.

       myStudy = stochD( 15, 3, 5, high() );

       //create a study that will be based on the close, using 15-min bars, regardless of 

       //the bar interval of the chart in which the script is loaded

       myStudy = stochK( 14, 1, 3, close( inv(15) ) );
