Stale quote data on stocks Quotes (v3) and Last Quote (v2) REST endpoints
Started 20 Aug 2026 15:20:36 (1 day ago), resolved 21 Aug 2026 23:08:58 (2 hours ago)
Major Incident
Resolved
Market Data REST Endpoints

We are investigating an issue where two stocks REST endpoints are returning out-of-date quote data: the Last Quote endpoint (/v2/last/nbbo/{ticker}) and the Quotes endpoint (/v3/quotes/{ticker}). Requests to these endpoints succeed normally with fast HTTP 200 responses, but the quote returned may be significantly behind real time — as of 11:17 AM ET, from a few minutes to roughly 90 minutes depending on the ticker.
