Update: the discrepancy between the QP Scan
and the AB scan is, at least partially, a result of the AB selection not
discriminating against Warrants, ADRs, preferred etc. Looking at my QP scanI
actually did ask for only "Common" which likely explains the reduced set
etc.
I just ran a AB scan, restricting the filter to
market=nasdaq, and group=stocks, and found yet another set of data - this with
3888, vw 4184 for the previous AB scan with only market filtered. This
change is a result of some stocks not being listed as "stocks", e.g. AAPL shows
as Group 255 for me. I suspect with the proper inspiration, and the
great new help in AB one could write a macro to clean up the
information.
Cheers,
Richard

I did not filter the scan, however they are the
stocks is QP2 and I think qp2 does some selection but I don't know what that
may be. Actually, I think I included the exact scan I used in the
previous communication.
I just realized, thanks to the
WONDERFULLY IMPROVED HELP IN 4.0! (Yelling intentional
:) ) that you can do something similar in AB by defining a filter for the
"market". I am currently doing a Exploration in AB with the following
code - crude but it appears to work.
------------
Filter = Close ><FONT color=#ff00ff
size=1>0;NumColumns=<FONT color=#ff00ff
size=1>1;Column0=<FONT color=#0000ff
size=1>MarketID(<FONT color=#ff00ff
size=1>1);-----
... finished.
It took significantly longer than the QP2 scan, a
little less than 5 min, but that is probably to be expected.
Surprisingly, the AB nasdaq file had some 4182 symbols, whereas the QP2 had
3767 symbols. Some may be explained by the recent number of disappearing
stocks - ENE, WBC etc, however, I don't find those on either list.
Cheers,
Richard

Thanks so much, Richard. The text files you sent contained a totalof
5605 tickers when combined. Certainly, there are more than that in the NYSE
and NAZ. Before you created these files, did you do a further filter?

One solution is to do a QP2 scan for
example,
Output="NYSE.txt";
IssueType =
common;Exchange=NYSE;
//AMEX,NASDAQ; // with the appropriate choice
println symbol;
and subsequently import the result into a
watch list in AB to use as a filter. Of course you could also exclude
thinly traded stocks if you choose.
I took the liberty of attaching the results
for the NYSE & NASDAQ.
Cheers
Richard

Hi, All:Sorry in advance for this brain warp
because the question certainly has been asked before, but I can't
remember the answer, I don't know how to search for it, so I'm going
to ask it again. I use QP2 as my data source, so I have over 9000
stocks in my database (and of course there's all those indices and
mutual funds, too). I'd like to limit the stocks I scan to only
those belonging to the NASDAQ and the NYSE (not the AMEX or any
other exchange). I know how to further filter on things like volume,
price, etc., but how do I limit my universe to only those in the
mentioned exchanges? Thanks, folks. I'm sure as soon as I pressthe
send button, the answer will dawn on me. Al
