Re: [EquisMetaStock Group] Relative Volatility to Volume in an Exploration HELP.

["Roy Larsen" <rlarsen@xxxxxxxxxxxxxx>]

Here's a set of formulas taken from the Equis web site that supposedly sets
out the construction of the RVI indicator.



@RVI Down

((PREV*13)+If(ROC(C,1,%)<0,Stdev(C,10),0))/14;



@RVI Up

((PREV*13)+If(ROC(C,1,%)>0,Stdev(C,10),0))/14;



@RVI

(100*Fml("@RVI Up"))/(Fml("@RVI Up")+Fml("@RVI Down"));



Now here's my version of the same code condensed into one indicator, and
with an option to apply it to whatever data array you prefer - just change
the target array.  The problem is that my formula and the set above both
give the same value buy this is different from the canned version in MS. I
can't find the reason for the difference. Can anyone else help?

  {RVI Indicator}
D:=Input("Periods",1,99,10);
X:=P; {target array}
A:=Stdev(X,10);
Up:=Wilders(If(ROC(C,1,%)>0,A,0),D);
Dn:=Wilders(If(ROC(C,1,%)<0,A,0),D);
100*Up/(Up+Dn);
