These operators are listed in the factor reference dictionary, but are not recognized.
I am interested in stddev,median,and sum, max.

Example screen is at
https://www.portfolio123.com/app/screen/summary/281563?st=1&mt=1

UnivExclude(“IBM”)
UnivMax(close(0))
UnivMedian(close(0))
UnivMin(close(0))
UnivRBICS(30)
UnivStdDev(close(0))
UnivSubset(“IBM”)
UnivSum(close(0))

The Univ… operators are for the Aggregate Series, not for screens or simulations. For screens and simulations, you want to use the F… operators: FMedian, FSum, and so on. If you go to the Factor & Function Reference (https://www.portfolio123.com/doc/doc_factors.jsp) and open the Formula Functions folder, you’ll see all of your options as “Cross Sectional” functions.
