Bob,
when I run a code like the one provided below, AB
successfully scans about 4-5% of my entire QP2 database and then crashes telling
me that GetExtraData failed plus somewhere in my code were bad
arguments.
Please use the code provided below and tell me
if you encounter the same, if you don´t mind.
Thanks
Markus

I meant that
you should use issuetype in a QP scan [see below]
In order see
what was happening, I scanned with IssueType Preferred; and imported the
list..
Voila, the
critters all returned "1".
Hence Filter =
GetExtraData<FONT
color=#000000>("IssueType"<FONT
color=#000000>) ==
"1";<SPAN
class=109391016-20052003> got them and != "1" should toss 'em out. Note,
however, that this way is much slower than doing it in QP and importing the
watcchlist.

Bob,
glad you stepped in here.
I used the
filter=getextradata("issuetype")=="p".
Weird enough, AB starts checking, then returns
error as below.
Would you mind checking if the code is correct
(i.e. finds ALL preferred) plus if you encounter the same error,
please????
Line 2, Column 40:Filter=
GetExtraData("issuetype")=="
p";---------------------------------------^
Error 18.GetExtraData failed
Many thanks
Markus

<SPAN
class=290302014-19052003>Why not simply do this in QP2 then create a
watchlist of your exported qp2 list? The advantage is that AB does not
need to chug through your whole database checking all your various
criteria since every stock in your watchlist will meet all your
criteria.When doing scans and explores you simply point to this
"Universe" of stocks.

[amibroker] String question
Hello,
I want to exclude all preferred stocks
from my scan.
In their symbols they either end with "
p" (space p) or with " p.." (space p followed by any other
letter).
While the first may be excluded by<FONT

(StrRight<FONT

" P"
how could exclude latter case since I don´t know which (if at all)
letter might follow??
Thank you for your help
