Phsst: I certainly support your concept and have often wished for such
a feature. I tried an elaborate system of AtoCs but found it difficult
and cumbersome to keep up to date. Not being a programmer, automating
it outside of AFL was also a nonstarter for me. So I support your
concept.
That said, such a suggestion would have to fall somewhere on Tomasz'
To-Do and Priority lists and I suspect would not show up for a long
time, if at all.
Sure wish there was some "canned" or almost "canned" examples of a
simple global, multiple stock index or quantity that knowledgeable
persons might post for others to use. (Hint Hint Fred---copy some code
from one of your scripts and share it with us--TIA).

Hey Fred,
You earned my respect a long time ago so quit pussy-footing around
with the 'stakes or silver bullets' stuff <g>.
If I get a negative (or no) user support for this suggestion then I'll
take a look at the Osaka dll. As far as ABTool goes... the author
deliberately 'burned the bridges' a long time ago.
Regards,
Phsst
