With my fat finger I sent off a total reload of the sim servers. Sorry about that. Should take ~40min
Is that all that has happened? I’m trying to move some models I’m working on to a new category (both the ranking systems and sims = trying to organize in categories); I’ve simply copied the ranking system to a new category name and also copied the sims to a new category name; HOWEVER, the returns are dramatically different even though it is “an exact copy”. I’ve tried several times but MAJOR return difference keeps appearing (even tried to “copy/paste” 2 different models):
OldQ, pretty sure it has to do with short interest fix: There are more N/A’s now in short interest as the last value is “expired” if no new data exists. see https://www.portfolio123.com/mvnforum/viewthread_thread,7296
Your ranking system has a large weight on an FRank of short interest that returns NA if outside an upper & lower limit of the FRank. I think I see were you going with this, but this node is hyper sensitive to the above change. Maybe the performance comes back by adjusting your upper/lower limits. I can try a few permutations later. However if slight permutations of your limits produce large differences I would be very wary. Short interest is not such a great data item : monthly values historically for a while, then bi-weekly, and some artificial lagging for older data.
PS: if you must use an upper/lower limit, try using Between() so you only invoke the FRank once for less computation, faster sims.
