I want to make a formula for the difference in width in bol bands  to use as an indicator which I can also later use in an exploration

BB diff   ==    BTM:=BBandBot(C,20,S,2) ;  TOP:=BBandTop(C,20,S,2) ; DIF:=TOP-BTM;    dif

with different stock prices , a simple difference doesn't work  and the "difference" needs to be expressed as a   -- ratio-- %-- index  -- a simple matter but I've forgotten how to make it work

I'd appreciate your assistance

thanks

Hi,

There is a Bollinger percent B (%b) formula described on various sites that a web search can turn up which might be helpful. The indicator below follows their definition:

Code:
B:=(C-BBandBot(C,20,S,2))/(BBandTop(C,20,S,2) - BBandBot(C,20,S,2));
B
