Re: [EquisMetaStock Group] Re: need some help on RSI code

[Steve Karnish <skeeter47@xxxxxxxxx>]

Here's a comparison of the Rapid RSI to a modified StoRSI.  I like the StoRSI better.  It's just as "rapid".  I believe it is less "nervous" and it defines tops and bottoms better than other momentum oscillators.
   
  Take care,

METASTOCK: Relative Spread Strength 
Ian Copsey's article in this issue, "Relative Spread Strength," 
introduces two variations on the relative strength index (RSI). The 
formula for these indicators and the instructions for adding them to 
MetaStock follow. 
To enter these indicators into MetaStock: 
1. In the Tools menu, select "Indicator Builder." 
2. Click New to open the Indicator Editor for a new indicator. 
3. Type the name of the formula. 
4. Click in the larger window and type in the formula. 
5. Click OK to close the Indicator Editor. 

Name: Rapid RSI
Formula:
tp:= 14; { time periods in RSI calculation}
plot:= C;
change:= ROC(plot,1,$);
Z:=Sum(If(change>0,change,0),tp);
Y:=Sum(If(change<0,Abs(change),0),tp);
Ytemp:=If(y=0,0.00001,y);
RS:=Z/Ytemp;
100-(100/(1+RS))

Name: Relative Spread Strength
Formula:
matp1:=10; {short MA time periods}
matp2:=40; {long MA time periods}
RStp:= 5; { time periods in RSI}
RSsmoothtp:=5; { time periods in smoothing of RSI}
plot:= Mov(C,matp1,E)-Mov(C,matp2,E);
change:= ROC(plot,1,$);
Z:=Sum(If(change>0,change,0),RStp);
Y:=Sum(If(change<0,Abs(change),0),RStp);
Ytemp:=If(y=0,0.00001,y);
RS:=Z/Ytemp;
Mov(100-(100/(1+RS)),RSsmoothtp,S)
