Write a selection question
Define the trend horizon and distinguish trend alignment from cross-sectional momentum. The default asks for close above SMA 200 and SMA 50 above SMA 200. A relative-strength ranking asks how a stock performed against other stocks over its documented period.
Read field units and lookback periods
Close 105, SMA 50 of 102 and SMA 200 of 100 satisfy the default alignment. A close of 105 with SMA 50 of 99 fails it. Moving-average values are prices; RS Rating is a 1–100 percentile measure, not RSI and not a percentage return.
Compare another question before combining rules
Compare long-term and short-term trend presets before adding relative strength. A strong-week rule can admit a rebound in a longer decline. Requiring both long-term alignment and strong relative strength narrows the question to their intersection.
securityType = "Stock" and indexMembership contains "SP500" and (rsRating >= 80)Inspect a match and a boundary exclusion
Examine higher highs and higher lows, extension from the averages and a recent correction. A current alignment is not a new crossover. Keep the documented lookback for each measure when comparing candidates.
Change one condition at a time and compare a row just inside the threshold with one just outside it. A zero-match result means the selected population did not meet the whole rule for that session; it is not a reason to silently change the question.
Save a reproducible research definition
Save the expression through the editor’s Library workflow. Record the selected session, population and sort so a later run can be compared meaningfully. A saved scan preserves rules, while a watchlist preserves symbols; their results can change independently.
