Manual works OK but you can't manually do what I
want. I am trying to run individual backtester over a watchlist so results
are reported for each opt step of each ticker ( for example, 10 tickers x 10 opt
steps = 100 lines in results window. I am using
AA.Optimize(1); // 1 = Individual
backtester
in the .js file to call the individual
optimizer. Seems to work fine except I would like
to have a ticker column to sort on. I found info on methods/properties of
Analysis object in the help file Object Model.
If you are interested in trying it, I have attached
the 2 files I am using. JS file has been renamed to tempjs - it is filled with a
bunch of comments because I am really trying to learn this COM stuff, and
especially the analysis object, once and for all.

I can't get it to show the tickers with the interation
like in your picture when I try it manually... How the heck are
you getting that? Try it manually and see if you can make it
happen.

Thanks D - here is a picture. I ran the
optimizer, individual mode, from OLE. The first column ( where the ticker
usually is ) now has the opt step, followed by the ticker in parens. When I
sort this column, it gets sorted by opt step.

You lost me on "the ticker is
prefixed by the opt step". Did you run Optimization, Backtest, ??
and what are you looking at: Report?, AA Results
list?
How about a picture, formula, ??

OK guys, thank you both *very much*, I
have the full blown version working now. 8 - )
Just one final question (pleeeease?). As
is, I can't sort by ticker because the ticker is prefixed by the opt
step. I am guessing that the best (only?) solution for
this would be to learn the custon backtest interface and add a column
with the ticker only?

you can't run an optimization via
ole/com WITHIN AB. You'll need to put the jscript code into an
external file with a .js extension and then run it by double clicking
the js file.

Hi All - I wonder if someone who is
good with COM/OLE interface could take a look at the small code
below and see if there is anything wrong? I am trying to call the
individual optimizer via COM/OLE, and I am getting the Amibroker
error message "Can not create that many optimization
variables", but I am only using one optimization variable. Can
anyone see some problem with the code that is causing this?
Thanks very much!

// enable an AFL scripting host
EnableScript ( "jscript" );
// AFL code
pds = Optimize( "Periods", 6,
3,
9,
3 );
Buy = Cover = Cross( Close, MA( Close, pds )
);
Sell = Short = Cross( MA( Close, pds ), Close
);
// begin script
<%
// create AmiBroker object
AB = new ActiveXObject( "Broker.Application" );
// retrieve analysis object
AA = AB.Analysis;
