Just adding my 2 pence in here. I also find constantly rejigging columns a real PITA. The AB Report Explorer is another area which suffers same problem. Sure we can export to Excel with macros, scripts, Autoit etc. but it is all extra files, scripts, debugging, maintenance most can do do without.
IMO it would be nice if user could define any number of "views" for a table (Backtest Report/or Report Explorer list). Each view defines the fields, field order and sort key(s) - these could be stored in plain text or xml.... Multiple views would be very useful as user often wants different set/order depending on what they are doing. Selecting and Applying a view to a table could be via RMB menu option on table. Defining a new view could similarly be invoked via an RMB option on table. With regard to maintaining Views (config file contents) a straightforward twin list type control dialogue (simliar to as used in AB Organise Catgeories) would enable users to easlly add/remove/order fields in an intuitive manner - little dcoumenation requiredi ;- An option to designate a particluar view as the default would be needed also. I would much prefer this type of solution than going down the route of coding formatting stuff into AFL code.

Re[2]: [amibroker] Re: How NOT to show all the built-in metrics in the backtester?Perhaps, if TJ doesn't plan on implementing individual column control, a much simpler feature might be just a switch allowing us to turn all columns on or off. Speaking for myself, I have written my own code for many of AB's stats, as well as other stats, originally for use in my charts but now I have added them to the backtest results also via the CBT, so I would be happy to just turn off AB's built-in stats ( would save a lot of scrolling and moving columns around ). Anyway just a thought, I don't know how others feel about it...

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.
Best regards,

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.
