This is what I have.  I don't recall who originally wrote it.

{ Function VIDYA }
Inputs: Length(NumericSimple), Smooth(NumericSimple);
Vars: Up(0), Dn(0), UpSum(0), DnSum(0), AbsCMO(0), SC(0);

Up=IFF(Close>Close[1], Close-Close[1],0);
Dn=IFF(Close<Close[1], AbsValue(Close-Close[1]),0);

UpSum=Summation(Up,Length);
DnSum=Summation(Dn,Length);

If UpSum+DnSum >0 then 
AbsCMO=AbsValue((UpSum-DnSum)/(UpSum+DnSum));

SC= 2/(Smooth+1);

If Currentbar=Length then VIDYA=Close;
If Currentbar>Length then 
	VIDYA=(SC*AbsCMO*Close)+((1-(SC*AbsCMO))*VIDYA[1]);
