Title: Re[2]: [amibroker] Re: How NOT to show all the built-in metrics in the backtester?

Column control was suggested long ago and I still think that being able to select, by disabling from afl (of course NOT using check boxes!) would be a good idea. I, without  exception after each and every Backtest, have to use the scroll bar to see my columns of interest. I greatly miss being able to add/suppress columns without the use of the CBT.


Since in the back tester column layout is fixed a simple afl function like HideColumns( 3, 2-9, 15 ) would do the job.


A alternate solution would be for Tomasz to publish a CBT backtester on the KB that would mimic the standard BT but provided the above option.


... while on the topic of reports ... it would also be nice to have the AddSummaryRows() enabled for portfolio backtests :-)


We have a wonderful product but there are always more wishes ;-))


Best regards,

herman

Hello,

 

"that no columns be displayed by default, and that the all columns and their widths be specified programmatically and/or in a settings page."

 

Since there are 46 build in stats, implementing your idea means 46 new checkboxes

and 46 edit fields (to define widths)

 

That's 92 new controls (to be placed on dialogs, docs and so on).

 

More settings -> more problems for beginners -> Lower sales. Plus more support

(every beginner asking "where is K-ratio", and "why there are no metrics produced?"

and "why there are so few metrics?")

 

From my perspective it would not be improvement. Just the opposite.

Ozzy --

Yes, at this point it seems to be easier to live with all the extra columns than to learn how OLE works.  


I believe, long ago, before the suggestion page was implemented on AB site, that I suggested to TJ that no columns be displayed by default, and that the all columns and their widths be specified programmatically and/or in a settings page.  Obviously the suggestion was not implemented.  IMHO, it would be a significant improvement over the present system.


I did get your previous response.  But I understand your concern.  I had to post my request three times before it finally went through.  My two others were on 1/14, 1:04am and 1/16, 1:39am.  Just recently these were finally delivered.  Yahoogroups can be unbelievably slow at times.

Keith - did not get around to implementing any OLE. Living with the

extra columns for now. But if I do write any code for it, will post it

here in the future.
