Thanks Graham - I used that in a Scan.
I still do not see why a Filiter= statement in an Explore should not have the desired result also. The AB Help states:-
"The idea behind an exploration is simple - one variable called filter controls which symbols/quotes are accepted. If "true" (or 1) is assigned to that variable for given symbol/quote it will be displayed in the report."
"Note that exploration uses all range and filter settings that are also used by back-tester and scanning modes so you can get multiple signals (report lines) if you select "All quotations" range. To check just the most recent quote you should choose "n last quotations" and "n=1" "
>From above I would expect any Filter= defined in AFL to be logically Anded with any Filters selected via AA User Interface to deteremine which symbols/quotes to process.

>> Brain fade today. Trying to create a few simple composites using ATC with a filter in Explore context (click Explore in AA). The Sector Index symbols are all assigned to Market 3. Although the AA explore list shows only the sector index tickers processed the ATC composite tickers have counts which indicate all symbols from databse have been counted. If I manually set Filter via AA dialogue to just include Market 3 then composites are correctly calcd just on Mkt 3 symbols. It appears the Filter= statement in afl file is not working as I thought it would.
