I'm aware I'm not answering your core question here, but I'll
tell you what I did/am-trying-to-do wrt calculating multiple
security stats. May be it'll be of some help, may be not.
I wanted to analyze patterns across (lots of) multiple securities
over (lots of) time, given a set of "input conditions". Since the
feature that you desire is lacking, I turned to a combo of
AFL/JScript code , where I write the data out (since displaying
it as Explore result causes severe memory problems), then import
it into Oracle (still working on this), and then plan to write a
little tool to try permutations of input conditions to see which
pattern holds.
Again, not sure if this is helpful, but if you want to, I'd be
glad to discuss it further...
