John Bollinger has applied Bollinger bands on indicators, thus giving a relative reading rather than 30 - 70 %. RSI is a bit special because it is self-smoothing as you get longer periods. This gives another approach to indicator reading.

Another indicator which is very interesting builf on the same basis of the RSI is the Money Flow Index which takes care of volume.

The lady's name is Constance Brown. Her web site is www.aeroinvest.com
She doesn't recommend the Bollinger Bands but instead uses ATR bands. BB's
give a totally different look.

I'm not sure how to create "Bands" on a oscillator, based on the "Average True Range" since the ATR function is derived from the days High and Low. I did manage to modify the "Denvelope" code to work on the "RSI". This code may be worthless....but here it is:

Relative Strength Index (RSI) Denvelope

pds:=Input("Periods",2,200,14);
sd:=Input("Standard Deviations",.01,10,2);
D1:= RSI(pds);
alpha:=2/(pds+1);
mt:=alpha*D1+(1-alpha)*(If(Cum(1)<pds,D1,PREV));
ut:=alpha*mt+(1-alpha)*(If(Cum(1)<pds,D1,PREV));
dt:=((2-alpha)*mt-ut)/(1-alpha);
mt2:=alpha*Abs(D1-dt)+(1-alpha)*PREV;
ut2:=alpha*mt2+(1-alpha)*PREV;
dt2:=((2-alpha)*mt2-ut2)/(1-alpha);
but:=dt+sd*dt2;
blt:=dt-sd*dt2;
blt;
dt;
but;

 

Best wishes,
