    WebSocket News Not Delivering Real-Time Data and No Support Response

    Date: Mar 01 2026
    Summary

    I rarely leave 1-star reviews, but my experience with Finnhub has been extremely disappointing.

    I subscribed to **Fundamentals-1** and **US Market Data**, specifically because Finnhub advertises WebSocket-based real-time news streaming. I am building a news-driven intraday trading system, so real-time delivery is critical.

    Here is the issue:

    * The WebSocket news feed delivers thousands of items — but they are all old (some months or even years old).
    * During US market hours, I receive zero newly published news items.
    * This is not just an initial backlog — the stream continuously provides historical data only.
    * The REST news endpoints *do* return recent data using the same API key, which confirms the key is valid and active.

    In short: WebSocket news does not provide real-time updates under my subscription.

    Even more concerning is the lack of support. I contacted Finnhub for clarification weeks ago and have received no response. No explanation about entitlements, no confirmation whether this is expected behavior, no technical guidance — nothing.

    For a paid data provider, this level of communication and transparency is unacceptable. If real-time WebSocket news requires an additional plan, this should be clearly documented. If it’s a technical issue, it should be acknowledged and addressed.

    At the moment, I cannot rely on this service for a production-grade system.

    Until there is clear communication and working real-time WebSocket news delivery, I cannot recommend Finnhub.

    – Jeroen

    Positive

    Broad API coverage (fundamentals, market data, news endpoints)
    REST endpoints appear to work reliably
    Pricing is competitive compared to some larger data providers
    Documentation is fairly extensive

    Negative

    WebSocket news feed does not deliver real-time data (only historical items)

    Unclear documentation about which subscriptions include real-time WebSocket news

    No response from support after multiple weeks

    Lack of transparency about entitlements and feature access

    Not suitable (in my experience) for real-time, production-grade news-driven systems
