thanks Tomasz, most helpful as usual.
thanks for getting me thinking about using the automation model within AFL.
I'd thought of it as a way to control AB from other applications, but I see
that there are things AB can do via OLE that AFL can't do directly.
and just for the record, I too agree that the enhanced backtester should be
a higher priority than custom stock fields, though they would be nice some
day.
