S4,
Try this:
a1:=BBandTop( CLOSE, 10, S, 2 )-BBandBot( CLOSE, 10, S, 2 );
(a1/mov(CLOSE,10,S))*100
If this doesn't do what you want you may need to get off of messenger
and go to the internet. Then go to the files section of the group and
look for formula sites. There are a number of them listed. Look for
Bollinger Band Width% at the sites.
Sorry, I don't see this as difficult or tricky.
