Helious: live US market news, releases scored on the print and Treasury auctions in seconds
Helious is a live US market news service for people who trade rates. It watches the wires, the Treasury, the statistical agencies and the Fed, and publishes the number the moment it lands: the economic release with its surprise against consensus, the auction with its tail and bidder split, the yield curve with a named regime. Reading it is free.
Every US economic release, scored against forecast the second it prints
When CPI, nonfarm payrolls or GDP crosses, Helious does not just repeat the number. It compares the print to consensus, sizes the surprise against how far that series normally misses, and puts the market reaction beside the headline. Every indicator keeps a permanent page with its release schedule, forecast, prior, full history and a CSV download. Start with the next CPI release date, nonfarm payrolls, US GDP release dates, or every indicator we track.
Treasury auction results in seconds: the tail, bid-to-cover and the bidder split
Helious posts the result of every US Treasury auction within seconds of the wire: the tail or stop-through in basis points, bid-to-cover against its own twelve-auction average, the indirect, direct and dealer split, and a one-word verdict of strong, in line or weak. Each tenor keeps a permanent page with years of history and a CSV. See 10-year Treasury note auction results, 30-year bond auction results, 13-week bill auction results, 4-week Treasury bill auction results, or read what an auction tail and bid-to-cover actually tell you.
The Treasury auction schedule and the week ahead
Every tenor page carries the date of its next auction, so the schedule is not a PDF you have to hunt down. The calendar shows the coming week of US releases and auctions with the time in ET, the forecast, the prior and the live result as it lands, and past weeks stay online at a permanent URL. See the Treasury auction schedule, this week's US economic calendar and the next FOMC meeting.
Treasury yields, the curve regime and what the Fed is saying
The rates board carries the whole US Treasury curve with the day's move in basis points, the 2s10s and 3m10y spreads, and a named regime: bull steepener, bear flattener and the other two, with a deadband so a rounding error is never called a trend. Fed speakers are tracked hawkish to dovish as they talk. See Treasury yields and the curve, the 2s10s spread and Fed speakers.

Helious for AI agents and models
Every number on the site is available as JSON and as tools, not only as a page.

Common questions
What is Helious?
Helious is a live US market news service run by TradeIQ Ltd in Glasgow. It scores every US economic release against consensus the second it prints, publishes Treasury auction results within seconds of the wire, tracks the yield curve and Fed speakers, and carries a live audio squawk. Reading it is free, with no card.
Where can I find US Treasury auction results today?
Helious publishes every US Treasury auction result within seconds of the wire: the tail or stop-through in basis points, bid-to-cover against its twelve-auction average, the indirect, direct and dealer split, and a strong, in line or weak verdict. Each tenor has a permanent page with years of history and a CSV download.
When is the next Treasury auction?
Every tenor page on Helious shows the date of its next auction alongside the last result, and the calendar lists auctions beside economic releases for the week ahead. Treasury announces sizes and dates in advance, and Helious carries the same schedule without the PDF, updated as each new announcement lands.
What is an auction tail?
The tail is the gap between the high yield an auction stops at and the when-issued yield trading just before the deadline, quoted in basis points. A positive tail means buyers demanded a higher yield than the market expected, so demand was soft. A stop-through is the opposite: the auction cleared through the market.
When is the next CPI or GDP release?
Each indicator on Helious keeps a permanent page with its release schedule, the exact time in ET, the consensus forecast, the prior value and the full history. CPI prints at 8:30 AM ET in the middle of the month and GDP at 8:30 AM ET on its quarterly schedule. The live actual appears on the page as it crosses.
What does it mean to score a release against forecast?
Helious compares the actual print to the consensus forecast, then measures that miss against how far the series normally deviates, so a 0.1 miss on a quiet indicator is not treated like a 0.1 miss on CPI. The result is a signed surprise score, published with the market reaction beside the headline.
Is Helious free?
Yes. Reading Helious is free and needs no card, with the public news feed running an hour behind live. A free account adds saved layouts, alerts and an API key with thirty days of history. Live data through the API and the MCP server starts at $14.99 a month, and $39.99 adds the live screen and squawk audio.
Can an AI assistant or agent use Helious data?
Yes. Helious runs a REST API, an MCP server with 20 tools, an A2A agent card and OAuth 2.1, so an assistant can request an auction result or a release surprise directly rather than scraping a page. Sample access needs no key, and every answer leads with a plain sentence, not a bare number.
