ShortAtlas methodology
Methodology and data sources
How ShortAtlas builds static US short-selling reference pages, ticker lookup data, rankings, and source disclosures.
Static data and update cycle
ShortAtlas uses static JSON data files generated from public regulatory short-volume data and Short Interest reference data. The website shows the latest available cycle that has been generated for the site.
Ticker lookup pages may also request a price reference through the ShortAtlas internal API when a user searches a supported symbol in the browser.
Source disclosure
Daily short-volume data is labeled on result cards as Public regulatory short-volume data. Full methodology disclosures identify regulatory datasets and limitations.
Supplemental quote references and ranking fields may use Yahoo Finance reference endpoints through ShortAtlas data generation or internal API flows. These fields are reference data and may be delayed or unavailable.
Limitations
ShortAtlas excludes OTC instruments in the MVP and does not show borrow fees, securities lending availability, predictions, recommendations, target prices, or trading advice.
Public datasets can lag market conditions and can differ by provider definition, reporting scope, and publication cycle.
