If I understand correctly, ATM does not work with dynamic OmniScan lists. But the original PortSim methods (e.g. % of Equity) do work with Dynamic lists. In PortSim, the last tab is "Trade Selection" which can be used to rank trades by a set of pre-defined criteria (e.g. BT HitRate, BT APR, ...). One criterion is "Advisor."
I would like the ability to define the "Advisor" ranker (or define a new "User Ranker") and thus have the ability to test dynamic OmniScan lists with the original PortSim methods.
My Motivation: Jeff Drake's "static" Resilient stock list has held up well over the past few months (and over the 15 year back test). I believe he created the list with an eye to what performed well during the 2008-2009 downturn. That list, even without DOG and the Bull stocks, has done very well throughout this year. But it's a hand-picked list. It would be nice to test the Resilient model (weekly allocating between the top n stocks) with dynamic lists. ATM lacks the ability to work with dynamic lists, but I was hoping that perhaps the original PortSim could do some user configurable ranking with minimal implementation effort based on the "Advisor" ranker.

Steve has an excellent point!
The Resilient method is amazing but its reliance on a fixed symbol list is a potential weakness going forward.
I can think of some resilient stocks that are selected each week that drag down performance because they are no longer in touch with today's market.
This is a brilliant suggestion to improve a great system going forward, THANKS STEVE, WELL DONE!
