# What Helious does

    Helious captures every US economic release, Treasury auction
    and Fed speech within seconds of the print, scores each one against expectations, and serves the result three
    ways: on a live screen, on a voiced squawk, and to software through an API and an MCP server. Reading it is
    free. Operated by TradeIQ Ltd of Glasgow.



## The live screen

    One screen carries the scored news feed, the economic calendar with consensus and actual for
    every US release, the market board with yields and the curve regime, sudden-move alerts, a one-line read of what
    is moving the session, the squawk player and the Ask Helious drawer. Every card is graded before it renders, and
    a grade never changes after it is published. The free screen runs an hour behind; [Pro](https://helious.io/pricing) takes
    every price live.



## Every US release, scored on the print

    When a release crosses, the actual goes up beside consensus and the miss is sized against how
    far that series normally deviates, so a small miss on a quiet indicator is not treated like the same miss on
    CPI. The result is a signed surprise in standard deviations, with the market reaction beside it. Each of the
    indicators Helious tracks keeps a permanent page with its next release date, the forecast, the prior, the
    captured history and a CSV. See [every indicator](https://helious.io/data), [every inflation measure on one chart](https://helious.io/inflation)
    and [every employment measure on one chart](https://helious.io/jobs).



## Treasury auctions, read in seconds

    Every US Treasury auction result is up within seconds of the wire: the tail or stop-through in
    basis points against the when-issued yield, bid-to-cover against that tenor's own twelve-auction average, the
    indirect, direct and dealer split, and a verdict of strong, in line or weak. Nobody else publishes the tail free,
    because it needs the when-issued yield as it stood seconds before the close. Each tenor, from the 4-week bill to
    the 30-year bond, TIPS and the floating-rate note, keeps a permanent page and the [tails dataset](https://helious.io/data/treasury-auction-tails)
    is downloadable. See [every tenor](https://helious.io/auctions) or [how to read an auction](https://helious.io/guides/how-to-read-a-treasury-auction).



## The curve regime and the session read

    The Treasury curve is classified live as one of four regimes, bull steepener, bull flattener,
    bear steepener or bear flattener, from the average move of the front and long legs with a dead band so a
    rounding error never becomes a trend. It is published with the time it flipped, what it flipped from and the
    previous close, and it is free to [embed on your own page](https://helious.io/embed/curve). Above it sits the session read:
    event-driven, event-adjacent, flow-driven or quiet, anchored only to releases that have printed, with the
    evidence attached. See [yields and the curve](https://helious.io/rates) and [the rate path](https://helious.io/rate-path).



## The Fed

    Every FOMC meeting has a page with the countdown, the statement and the minutes. Every official
    has a page with their speeches, their lean from hawkish to dovish, and their upcoming appearances. Live press
    conferences and hearings are transcribed as they run. See [FOMC meetings](https://helious.io/fomc) and [Fed speakers](https://helious.io/fed).



## Helious Squawk

    A voiced station built from the data. Every admitted print is spoken within seconds of its
    card, and the measured latency is published on the [methodology page](https://helious.io/methodology). Live events are
    transcribed and the market-relevant lines are read out as they happen. Sessions
    stay available for seven days. The squawk is free with a short delay and live on [the paid plans](https://helious.io/pricing).
    See [how it compares](https://helious.io/compare) with the subscription squawks.



## Ask Helious

    An analyst inside the terminal that answers in plain English over the same data, shows the
    numbers it used, draws a chart when one helps, remembers your positions, and can set an alert or follow up when
    a release prints. Answers can be shared at a permanent address. Free accounts get one question a day; paid plans
    carry a monthly allowance. See [how it works](https://helious.io/help/ask-helious).



## For software and AI agents

    Everything above is also a machine endpoint. A REST API with a public OpenAPI description. A
    WebSocket stream open on every plan, live on Ultimate. An MCP server over streamable HTTP, listed in the official
    registry, with a tool for every board, hub and feed. An A2A agent card, OAuth 2.1 sign-in with dynamic client
    registration, llms.txt and a Markdown twin of every page at its .md address. The first call needs no key, every
    plan sees the same endpoints and the same response shapes, and nothing breaks on upgrade. See
    [the API](https://helious.io/developers/) and [Helious for AI agents](https://helious.io/ai/).



## How it stays right

    Every tier-one series is captured by at least two independent paths. A value passes six gates
    before it reaches the calendar, and a vintage guard refuses any number held from before the release. A card is
    graded within ten seconds and then frozen. A clock guard refuses anything dated in the future. The rules behind
    every scored read are written down on the [methodology page](https://helious.io/methodology), and a number on any indexable
    page can be traced to a primary record. None of it is investment advice.
