macd( fastLength, slowLength, smoothing [, source | sym() | inv()] [, barIndex] ) macdSignal( fastLength, slowLength, smoothing [, source | sym() | inv()] [, barIndex] ) macdHist( fastLength, slowLength, smoothing [, source | sym() | inv()] [, barIndex] )
MACD is short for Moving Average Convergence Divergence. The MACD looks at the difference between a short-term moving average and a long-term moving average. A third moving average is taken of the difference and used as a signal line.
Parameters
To Create a Series
var myStudy1 = null; var myStudy2 = null; var myStudy3 = null; var bInit = false;
function main() { var myVar1; var myVar2; var myVar3;
if ( bInit == false ) {
myStudy1 = macd( 12, 26, 9 ); myStudy2 = macdSignal( 12, 26, 9 ); myStudy3 = macdHist( 12, 26, 9 );
bInit = true;
}
//retrieve the current values myVar1 = myStudy1.getValue(0); myVar2 = myStudy2.getValue(0); myVar3 = myStudy3.getValue(0);
return new Array( myVar1, myVar2, myVar3 );
}
To Retrieve a Single Value
function main() {
... ... myVar = macd( 12, 26, 9 );
//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 = macd( 12, 26, 9, 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 = macdSignal( 12, 26, 9, 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 = macdHist( 10, 18, 5, 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 = macd( 12, 26, 9, sym( "MSFT,30" ) );
//create a study that will be based on the high. myStudy = macd( 10, 20, 4, 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 = macdHist( 12, 26, 9, close( inv(15) ) );
