Re: [EquisMetaStock Group] ravi and cti

This is RAVI from Chande's book "Beyond Technical Analysis".

  {RAVI}
Abs(100*(Mov(C,7,S)-Mov(C,65,S))/Mov(C,65,S));

This is the Chande Trend Index that I have.

  {Chande Trend Index}
n:=Input("# of n periods",1,34,21);
i:=Input("# of i periods",3,34,20);
A:=Log(Ref(C,-i)/Ref(C,-(i-1)));
Xt:=Sum(A,i)/n;
B:=A-Xt;
Bi:=Sum(B,i);
St:=Sqrt(Power(Bi,2)/n);
CTI:=Abs(Log(C/Ref(C,-n)/(St*Sqrt(n))));
CTI
