Just
downloaded each of these from Yahoo ( 3 or 4 years data) and with QuickAFL
disabled I can see no problem. With QuickAFL I still see an intermittent
problem but hitting apply from the edit formula box corrects the graph..
Unless I can get some data which allows me to replicate your problem Iam
not sure what I can do. Tomasz mentioned short data histories so perhaps
if you let me know the start date for your data I could set my data tothe
length you are using. The other thing you could try is opening the edit
formula window and clicking apply (making sure that automatic scaling and Level
0 are set) and letting me know what happens.

If
you let me know 5 or 6 symbols which are incorrect I will set up a Yahoo
database and see what the problem is. Unfortunately I tested the DLL
with TC2000 data and no bugs appeared during testing.

Hello,
Yes we were talking about elders.dll. I just wanted to
verify if the problem is inside AmiBroker or
is it in elders.dll. I checked both. I also have
negative values with elders.dll for symbols with short
histories.
The problem does not exist for
scripting version.
So it appears that DLL version has a bug. But... this
can only be fixed by Stefan (not me - sorry),
simply because Stefan has written the DLL and
generously offered it to the group.
Best regards,Tomasz Janeczkoamibroker.com

<FONT face=Arial color=#0000ff
size=2>Sorry, Tomasz...the vbscript version DOES work....it's the
elders.dll version that does NOT work with SOME symbols. This is
the version, I think we are talking
<FONT face=Arial color=#0000ff
size=2>about. The price scale is in the NEGATIVE millionsand
that's why there is the arc in the attachment I sent recently.
Your version works...

Make sure that you have Level 0 and middle set in indicator

deselect QuickAFL as with this enabled when moving between
