Dennis --
TJ in his posting said, "XML is plain text file editable with Notepad or
any editor". So, I assume that he expects me as a user to not just
copy verbatim a file which he has provided, but to somehow
modify it.
I just looked up XML on Wikipedia. The description is extensive. I
also looked for XML books on Amazon. The first one in a multi-page
list is called "XML for Beginners", and is 1080 pages long.
Also, I can't see how "HideColumn" would clutter up my formulas any
more than AddColumn, SetOption, or any other function does now. When
the clutter gets to much for me, I can always use #include.

Friends,
I for one do not care if additional flexibility is crated by XML files,
plain text files, DLL files, JScript, AFL includes, OLE... blah blah
blah.
It does not require learning a new language to use something
that was written in a different language.
I do not personally use anything but indicator mode for my
systems, so I am not biased for or against this particular item.
However, I have a keen interest in similar solutions proposed for
other functionality that I do use, and I am all for it.
Give me any "reasonable" way to get additional functionality
into AFL. If a reasonable way is available that can be expressed with
an include AFL file, it does not matter the details of the language,
because all that can be hidden inside a function or include.
For example, If a function required a JScript language to set
certain s ettings via ActiveX who cares. Just give me the script and I
will use it. I don't have to even know JScript or ActiveX at all to
use it. Wrap it in an AFL function and stuff it in an include with a
bunch of other nifty functions and I would be quite happy.
Need an XML file to control something, fine! Make an AFL
program the takes parameters and generates the XML text file and give
it away to everyone, or generate it on the fly with an AFL function
that takes all the parameters and stuff it into an include.
We have a wonderful tool with AB and AFL. When TJ offers to
expand it to your needs in a way that meets his also... jump at it!!!!
I only wish I had more opportunities to do that with my requests.
BR,
Dennis

As to suggested "HideColumn" AFL
function suggested by Herman, that would not be best, IMHO, because it
will clutter every formula
(as I guess people would want to
hide unneeded columns for every backtest they run) a nd make it slower.

I am glad you liked it. 8 - ) I don't know anything about XML or how that would work, but I
would guess that most users would prefer not to write all their own
stat functions from scratch, so perhaps your XML idea ( which sounds
more flexible ) might be appreciated by more users?

That's not bad idea :-). Either
this or XML config file that you can manually edit would be solution
for advanced users.

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...

[amibroker] Re: How NOT to show all the built-in metrics in the

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
sol ution 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 ;-))

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.
