efsExternal()

Parameters

Usage

function main() {

var myVar;

var myPlot;

       ...

       ...

       //call an external EFS called "myCustomEFS.efs" and load it into

       //the context of IBM 15-min bars. we also pass two parameters

       //to the script.

       myVar = efsExternal( "myCustomEFS.efs", sym( "IBM,15" ), 20, 5 );

       //assuming that "myyCustomEFS.efs" returned 3 values, we would use

       //the following logic to retrieve just the 2nd return value. The first

       //value returned would be seriesIndex 0, second value would be

       //seriesIndex 1, etc.

       var myPlot = getSeries( myVar, 1 );
