Dear Thomas, 

"BINGO", you hit the jackpot!
I followed your instructions and found everything to be working
perfectly. 

Thanks much for your insight. 

Best Regards, 

Hal

Dear Hal,
 
I have just tried to reproduce the behaviour with the
settings
you described and was not able to get any wrong results.
 
I used very simple check formula:

Filter =
1;

Buy =
1;

Sell =
1;

AddColumn(Close,
"close");

 

with scan/exploration and back test modes and I
always get only the tickers
that belong to the watch list (correct).

So please double check all settings (especially the filter - click CLEAR
on both Include and Exclude
pages and select your watch list once again - then click OK and check
if
Apply to radio button is set to "Filter")

Best regards,

Hi Tomasz et all,


I just happened to notice that I was getting "weird" tickers selected in my favorite SCAN run. 


In order to reduce the time involved in each scan (approximately 2 min, 50 sec) of 2800 tickers, I generated a watchlist of those tickers I consider to be within my price range. This watchlist is 950 tickers long, hence my scan is now under a minute.


The above would be a true statement if it worked.


The problem is, although I have tried all combinations of Range:


Apply To:  USE FILTER
Define:     Watchlist name is properly selected in the INCLUDE window
Range:     Have tried three different selections of:
                Last Quotations = 1
                Last Days          = 1
                From To Dates  =  Identical Date


The watchlist IS up to data with data.
Under all of the above conditions I get tickers selected that are NOT in the watchlist.


I therefore assume that there might be a switching problem somewhere in AB effecting my watchlist selection. 


My AB version is;  3.80.4  Build date: Nov. 29, 2001


I would appreciate any assistance which would instruct my AB program to "Do what it's told to do."


Best Regards, 


Hal
