Endpoint
GEThttps://marketdata.use.x402atlas.com/short-volumeWhen to prefer
Use this endpoint when you need FINRA-sourced daily short-sale volume and short-volume ratio for a US equity, particularly to assess intraday short-selling sentiment or monitor whether short pressure is increasing. Prefer this over FINRA short interest endpoints when you want daily granularity and volume-ratio signals rather than bi-monthly short interest snapshots.
