Steve,

Can you send me the afl at an attachment?
maybe my copy and paste did something to it

Thank you

Mark

Hi - If the params look weird, that sounds like AB thinks it is all one code and there are dup names in the params - perhaps it is not adding the Section_Begin and Section_End lines? Before going further, can you dragging and dropping all copies to the chart? That's what I do and so far so good.... Thanks!

Yes of course

First running prof v 5.20

I open up a tap and put the seasonality.afl in and it shows one chart ( line) and I set it for the time period I want
then I go to charts and click on the Seasonality.afl and click overlay, the parameters window opens up but it is blank, I close it open it up again and have two sets of parameters one for each year and set the last one

Then I go back again and click on seasonality.afl click on overlay and then the parameters box opens again blank and on the header instead of having three seasonality?s there now there are four lines. I close the parameters box and then open it again and only have two Seasonality there to set

Attached is the chart I end up on the third overlay along with the Parameters box and the updated afl too

Thank you for your help

Hi Mark - I jusr checked mine, it is still working fine with 12 copies dropped on the same chart. If you can be more specific about what is happening I could try to work with you to fix it...

Steve,

Great code

Question

Is there a reason why I may not be able to apply more than two of the alf?s at a time?

I open one then overlay another and on the third one it will not work anymore

Thank you

Hi - I was looking at that old Seasonality chart today and decided to make a
couple of improvements. New code is below. Changes ( shown in attached pic )
are
1. new title format
2. can set to foreign ticker now
2. scroll current year backward, then match dates to see "projected" market
direction from other years
3. setting begin/end values shows color-coded performance for that period in
the title

No more changes coming so it is safe to "upgrade" if you want. 8 - )
