Hello jlongwill,

A 940 week offset may exceed our historical data depending on the symbol/interval. However, adding an offset can easily be done with EFS2's offsetSeries() function. Wrap the open, high, low and close calls starting at line 99 with the offsetSeries() function like below.

var o = offsetSeries(open(sym(vSym)), nOffset);
var h = offsetSeries(high(sym(vSym)), nOffset);
var l = offsetSeries(low(sym(vSym)), nOffset);
var c = offsetSeries(close(sym(vSym)), nOffset); 

The nOffset variable can be established as a hard coded value, or you could add it to the other functions parameters in preMain using the
FunctionParameter Object. Here's an example of what to add to preMain for the nOffset parameter.

        var fp2b = new FunctionParameter("nOffset", FunctionParameter.NUMBER);
            fp2b.setName("Offset");
            fp2b.setLowerLimit(0);        
            fp2b.setDefault(0); 

The only other thing you would need to do is add nOffset to main()'s parameters like below.

function main(Symbol1, NumBars, nOffset, BarThickness, Ucolor, Ncolor, Dcolor) {
