Parabolic SAR

eSignal EFS 2

Parabolic SAR

sar( start, increment, max [, source | sym() | inv()] [, barIndex] )

Parabolic SAR is a display of "Stop and Reverse" points for a particular market. When the market touches or crosses a point, this indicates you should reverse your position. If you are long, for example, go short. If you are short, go long. The Parabolic SAR assumes that you are always in the market.

Parameters

start	starting sar value
increment	acceleration factor
max	max sar value
source	optional. input series for the study	default: high and low
sym()	optional. specify a symbol to use	default: current symbol
inv()	optional. specify a bar interval to use	default: current interval
barIndex	optional. bar index of value to retrieve	default: current value

To Create a Series

var myStudy1 = null;

var bInit = false;

function main() {

var myVar;

if ( bInit == false ) {

myStudy1 = sar( 0.02, 0.02, 0.2 );

bInit = true;

}

//retrieve the current value

myVar = myStudy1.getValue(0);

return( myVar );

}

To Retrieve a Single Value

function main() {

...

myVar = sar( 0.02, 0.02, 0.2 );

//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 = sar( 0.02, 0.02, 0.2, 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 = sar( 0.02, 0.02, 0.2, 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 = sar( 0.02, 0.02, 0.2, 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 = sar( 0.02, 0.02, 0.2, sym( "MSFT,30" ) );

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

myStudy = sar( 0.02, 0.02, 0.2, 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 = sar( 0.02, 0.02, 0.2, close( inv(15) ) );
