To create a scan that will sum up all the volume data for all stocks in
the S&P500 Index I have created this afl file:
Buy = 0;
Sell = 0;
AddToComposite(Volume,"~sp500volume","Volume", flags = 1);
I have also created a small symbol list (symlist) made up of 9 stock
symbols and saved it as one of the Watch Lists.
I have also created the following Indicator:
_SECTION_BEGIN("sp500volume");
vol = Foreign("~sp500volume", "volume", 1);
Plot(Vol, "SP500Volume", colorBlack, 2);
_SECTION_END();
When I do a Scan in Automatic Analysis I click on "use filter" in the
"Apply to" area and define the filter as my my small symbol list
(symlist). In the "Range" area I click on "all quotations". I then
run the Scan and nothing happens. If instead of using my symlist I
click on "all symbols" in the "Apply to" area the scan runs for several
minutes and I see the volume bars update on my stock chart at the end of
the scan. So everything is working except for being able to run the
scan on a selected list of stocks. Once I get this to run on a small
list of stocks I will then use a stock list of 500 stocks that make up
the S&P500 Index. Anyone have any suggestions to get this to run on a
select list of stocks instead of all the stocks in my database?

Alan
