Illustrative preview — sample data, including planned features.
Filters that mean something
Period-based ranked signals use fixed 30-day periods so cards are compared on the same horizon; relative strength uses calendar months. Card-page signals adapt their periods and may show different values. Tooltips explain unavailable readings.
Save a thesis
Save a named screen — "Quiet Accumulation", "Vintage on sale" — and revisit its matches as the data updates.
Know what can be measured
LOW DATA identifies cards that cannot meet a selected metric’s requirements. Results link to the Card page for its sales history and signals. Churn and census filters are not available yet.
