I saw your post #5167, Roy. Was struck mostly by the small difference between #1's 9 minutes and #4's 8 minutes.
Because Q+ doesn't have short-circuit operators, very large improvements are sometimes realized by replacing AND with nested IFs.
Look especially at some of the scans on Brooke's site that use long custom formulas such as StochRSI. Nesting with optimum ordering (most restrictive IFs first) is an effective substitute for prescreening.
