chop( length [, source | sym() | inv()] [, barIndex] )
Choppiness is a function of market direction. A market that is trending has a low choppiness number while a trend less market has a high choppiness number. The Choppiness Index ranges between 0 and 100, the higher the index the choppier the price action is and the lower the index the more trending the price action.

var myStudy = null; var bInit = false;
function main() { var myVar;
if ( bInit == false ) {
myStudy = chop( 12 ); bInit = true;
}
//retrieve the current value myVar = myStudy.getValue(0);
return( myVar );
}
To Retrieve a Single Value

... ... myVar = chop( 7 );
//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 = chop( 15, 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 = chop( 15, 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 = chop( 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 = chop( 14, sym( "MSFT,30" ) );
//create a study that will be based on the high. myStudy = chop( 15, 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 = chop( 20, close( inv(15) ) );
