Major August 20, 2026 Stale quote data on stocks Quotes (v3) and Last Quote (v2) REST endpoints 1d 7h Market Data REST Endpoints

Started Aug 20, 2026, 03:20 PM UTC· resolved Aug 21, 2026, 11:08 PM UTC

  1. investigating Aug 20, 2026, 03:20 PM UTC

    We are investigating an issue where two stocks REST endpoints are returning out-of-date quote data: the Last Quote endpoint (/v2/last/nbbo/{ticker}) and the Quotes endpoint (/v3/quotes/{ticker}).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.

  2. investigating Aug 20, 2026, 04:18 PM UTC

    The v2 Last Quote (/v2/last/nbbo) and v3 Quotes (/v3/quotes) stocks endpoints are still serving stale quotes, and the lag has grown since 9:30 AM ET (market open). Staleness varies by symbol: some are current, others are more than two hours behind.

  3. identified Aug 20, 2026, 06:53 PM UTC

    Some stocks symbols on the v2 Last Quote (/v2/last/nbbo) and v3 Quotes (/v3/quotes) endpoints are serving current quotes again. A small number of symbols remain delayed and are not yet catching up. Check the sip_timestamp/t field for any symbol you depend on before relying on the data.

  4. monitoring Aug 20, 2026, 08:41 PM UTC

    Quote data on the v2 Last Quote (/v2/last/nbbo) and v3 Quotes (/v3/quotes) stocks endpoints returned to normal at approximately 3:49 PM ET, and affected symbols caught up before the 4:00 PM ET close.

  5. resolved Aug 21, 2026, 11:08 PM UTC

Major June 15, 2026 Options trades unavailable on WebSocket 19h 25m Market Data WebSocket Channels

Started Jun 15, 2026, 07:27 PM UTC· resolved Jun 16, 2026, 02:53 PM UTC

  1. investigating Jun 15, 2026, 07:27 PM UTC

    We're investigating an issue where options trade messages aren't being delivered over our WebSocket channels. Other options data and our REST endpoints aren't affected. We're on it and will share an update shortly.

  2. identified Jun 15, 2026, 07:37 PM UTC

    We are investigating degraded performance on the real-time Options WebSocket feed. Connections authenticate normally, but subscriptions are taking significantly longer than usual to activate (currently around 2-3 minutes instead of seconds), and some connections are being dropped before data begins streaming. Once a subscription activates, data is delivered in real time. Options REST endpoints and the 15-minute delayed Options WebSocket feed are unaffected. Clients with short connection or subscription timeouts may fail to receive data and should allow extra time or retry.
