- Its Purity score is 100 divided by a lookalike group’s size; the page cautions that this measures uniqueness, not quality or performance.
Field notes
Filters cover region, provider, exchange, category, and Purity, with a one-per-basket deduplication option and CSV export control. The atlas lists 64 exchanges and 20 guessed providers; its provider and regional labels are described as inferences from names, symbols, and exchanges. A graph-and-density view and a method-and-data-source page are also linked.
