    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
