Hello,
 
You are using special option that is NOT available when running optimization manually. In such case you have to deal with results on your own
(export them to CSV file and process externally).

Best regards,

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!

Steve

 

// 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;

// set which tickers to run on

AA.ApplyTo = 1; // 1=current ticker

// set range

AA.RangeN = 15; // last 15 quotes

// set range type

AA.RangeMode = 1; // 1=n last quotes

// select which module to run

AA.Optimize( 1 ); // 1=individual

// report results

AA.Report( "" ); // display report if "path/filename" is empty string

// end script
