AL,
The original article was in "Technical Analysis of Stocks and
Commodities" October 2006. The codes are provided by William Golson
at Equis.
Basically the Rapid RSI is a non smoothed version of the RSI. The RSI
originally used Wilder's smoothing which is half of an exponential
smoothing.
The Relative Spread Strength is more like a RSI of a MACD where the
MACD is a 10 and 40 period rather than the traditional 12 and 26.
If you want just the Rapid RSI use this:
{Name: Rapid RSI
Formula:}
tp:= 14; {time periods in RSI calc}
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))
{end}
