Sine Wave Moving Average

[whatever]

Could someone please convert the following MetaStock code to EFS.

Sine-Wave Weighted Moving Average

PI:=3.1415926;
SD:=180/6;
S1:=Sin(1*180/6)*C;
S2:=Sin(2*180/6)*Ref(C,-1);
S3:=Sin(3*180/6)*Ref(C,-2);
S4:=Sin(4*180/6)*Ref(C,-3);
S5:=Sin(5*180/6)*Ref(C,-4);
Num:=S1+S2+S3+S4+S5;
Den:=Sin(SD)+Sin(2*SD)+Sin(3*SD)+Sin(4*SD)+Sin(5*S D);
Num/Den

Here is the web page with a graph of the MA.

I have attempted the script but the MA does not look like the one at the above web address.

Thanks

Enclosed is the efs equivalent
Alex

function preMain() {
    setPriceStudy(true);
    setStudyTitle("SineMA");
    setCursorLabelName("SineMA");

}
function main() {

var SD = Math.PI/6;
var S1 = Math.sin(SD)*close();
var S2 = Math.sin(2*SD)*close(-1);
var S3 = Math.sin(3*SD)*close(-2);
var S4 = Math.sin(4*SD)*close(-3);
var S5 = Math.sin(5*SD)*close(-4);
var Num = S1+S2+S3+S4+S5;
var Den = Math.sin(SD)+Math.sin(2*SD)+Math.sin(3*SD)+Math.sin(4*SD)+Math.sin(5*SD);

return Num/Den;
}

Thank you Alexis

Whatever:

I posted a SineWeightedMA version about a week ago that uses the same logic but also allows you to change the period.
