Need Afl for BBand

[pra1968]

Dear All,

I need an AFL for

exploration where today s Bollinger band is greater then or lesser then previous day

(Todays BBandTop - Todays BBandBot) < = (Yesterdays BBandTop - Yesterdays BBandBot)

OR
(Todays BBandTop + Todays BBandBot) < = (Yesterdays BBandTop + Yesterdays BBandBot)

or in any other sense as you like....


thanks

use this one. Previous one gives different values from orginal bb values. If i use "periods" param it gives different values. So i made a tiny change.

and again check before use pls.
