Alvin,
Preston had answered your question.
Quoting from his email:
{Adaptive RSI System with an idea
Taken from the November 2005 Active Trader article}
x:=Input("number of periods for RSI",1,2000,14);
sd1:=Input("standard deviation constant",0.1,5,2);
bs1:=Input("Bollinger Band Smoothing",1,200,100);
bbandtop( RSI(X), bs1, S, sd1 );
bbandbot( RSI(X), bs1, S, sd1 );
RSI(x); {end}
or (if you want to make the code fix, like in the article you
mentioned), you can use:
BBandTop(RSI(14), 100, S, 2); { this will draw the lower
Bollinger Band }
BBandBot(RSI(14), 100, S, 2); { draw the upper Bollinger Band }
RSI(14); { draw the RSI line }
that's it.
I, myself, will prefer Preston's code, since it is more customizable.
Besides using BB on RSI, you can also try applying BB on other
indicators, such as StochRSI, MFI, OBV, etc, to add more relativity to
the result.
