In another attempt to rank in a different manner I spent a week or so
trying the get the Osaka plug in to produce ranked results. I have
been able to get it to do only the simplest of tasks. As soon as I
try to set it up to actually rank some real indicator values I have
severe problems with the AB code to get the symbols and indicator values
into Osaka, let alone trying to get the supposedly ranked values out of
the table. I have read all the Osaka related posts and tried all
the code examples, no joy.
Hers is some code I have been working with. There is probably more
than one error in here.
/*
The code below should be explored against a smallish watchlist, say 20
symbols. It creates AND saves a table while the first stock is being
processed, AND instead of recreating it for subsequent stocks, loads it
from
disk. The idea is that if lots of processing was required to create the
table (unlike this simple test), it'd only have to be done once for the
whole test run.
