Hello,
I am looking for the Klinger Volume Oscillator (KVO) in afl script.
May I request help for this ?
AFL written by me is not seems to be accurare. I think, Loop should
be used in AFL, which I am not conversent with. AFL written by me is
as under:-

/////////////////////////////////////////////////////////////////
a=H+L+C;
b=Ref(a,-1);
Trend=IIf(a > b, 1,-1);
//dm = daily movement
dm = H - L;
Cm = Cum(dm);
Cm = IIf(trend=-1,Ref(Cm,-1)+dm, Ref(dm,-1) + dm);
Vf= V * (2 *( dm/Cm -1)) * trend * 100;
KO = EMA(Vf,34) - EMA(Vf,55);
Plot(ko,"KO",colorBlue,styleLine);
TL = EMA(KO,13);
Plot(TL,"TL",colorBlue,styleLine);
////////////////////////////////////////////////////////////////

Mathamatical Experssion of KVO availabe at:-

Thanks in advance.
