what  is function version used for and what is indicator version used for??

Can you please tell me how to create a scan to find a stock or stocks whose current  bandwidth is a minimun for its stock for, say, 126 days. This is what Bollinger scans for re: bandwidth.

Your help section lists the site of more information about VZO as the 2008 IFTA Journal. In fact, the article you reference is at page 18 of the 2009 Journal.

Hi Bruce,

How do I import a list of stocks in Excel into a watchlist?

Bruce,

As always, thanks for your help.

Bruce,

Thanks, but

If I understand you correctly, after making the change you suggested and assuming I made no error, I expected to get identical results with each of the formulas. But I did not.

Why is this?

What does each of these formulations represent, if you please?

(v*(2*c-h-l)/(h-l))  for 21 periods, and

((2*C-H-L)/(H-L))*v + ((2*C1-H1-L1)/(H1-L1))*v +((2*C2-H2-L2)/(H2-L2))*v + ((2*C3-H3-L3)/(H3-L3))*v +((2*C4-H4-L4)/(H4-L4))*v +((2*C5-H5-L5)/(H5-L5))*v + ((2*C6-H6-L6)/(H6-L6))*v +((2*C7-H7-L7)/(H7-L7))*v + ((2*C8-H8-L8)/(H8-L8))*v + ((2*C9-H9-L9)/(H9-L9))*v + ((2*C10-H10-L10)/(H10-L10))*v + ((2*C11-H11-L11)/(H11-L11))*v + ((2*C12-H12-L12)/(H12-L12))*v + ((2*C13-H13-L13)/(H13-L13))*v + ((2*C14-H14-L14)/(H14-L14))*v + ((2*C15-H15-L15)/(H15-L15))*v + ((2*C16-H16-L16)/(H16-L16))*v + ((2*C17-H17-L17)/(H17-L17))*v + ((2*C18-H18-L18)/(H18-L18))*v +((2*C19-H19-L19)/(H19-L19))*v + ((2*C20-H20-L20)/(H20-L20))*v

Why are they not the same?

Bruce,

That's great.

You're very good at what you do. Thanks.

Do you have a scan condition to find the minimum bollinger band width within the past six months?

tedk13

Bruce,

Thanks, again, for your patience and helpfulness.

I have found that I CAN scan on Time Series Forcast although NOT on Moving Linear Regression. Because these indicators are virtually identical, I'm all set.
