moving average of the difference of two moving averages

[fx9]

what's the efs program code for this metastock formula:

MOV( MOV(C,3,S) - MOV(C,13,S), 3, S)

where C=close()
S=simple Mov Avg

There are several ways in which it could be written. The simplest is to use the dsDiffSeries() function which is included in the dsFunctions.efsLib function library programmed by Chris Kryza and available here together with its User Guide.
If you used that function then you would first call the library and then in main you would simply create a moving average of the function

var myLib = addLibrary("dsFunctions.efsLib");
var myStudy = null;

function main(){
    if(myStudy==null) myStudy = sma(3, myLib.dsDiffSeries(sma(3), sma(13)));
    //rest of your code 

Then use myStudy.getValue(0) for your return statement

Execllent!
This does the job quite elegantly.

Thank you
