From: http://www.amibroker.com/devlog/index.php?s=addtextcolumn
AddColumn( IIf( Buy, Asc("B"), Asc("S")), "Signal", formatChar );

See ValueWhen: http://www.amibroker.com/guide/afl/afl_view.php?id=163
TriggerIndex = ValueWhen(Trigger, BarIndex());

It's possible, but complicated and takes a long time to complete since you effectively have to sort at ever symbol iteration. It would be *much* easier to run the scan, sort by hand and then just add the top 10 to a watchlist.

Very recently Tomasz added the ability to sort the columns programatically. However, I believe that your custom columns would only be sorted relative to each other, not to the standard columns (not sure, haven't tried yet).

Probably do-able. But, this would likely better be done via a separate JScript file using Ole Autmation: http://www.amibroker.com/guide/objects.html
Else, using BatMan for batch processing, found in Files section of this group.

Choose detailed reporting from AA settings: http://www.amibroker.com/guide/w_settings.html

I can't help you with this one.
