US Treasury yields, the 2s10s and other spreads, and the curve regime (bull or bear, steepener or flattener) with the time it flipped. Prices are live on Pro and Ultimate, one hour behind on Starter, and answer with upgrade steps on the free tiers.
Treasury yields and the curve regime — US Treasury yields, the 2s10s and other spreads, and the curve regime (bull or bear, steepener or flattener) with the time it flipped. Prices are live on Pro and Ultimate, one hour behind on Starter, and answer with upgrade steps on the free tiers.
Curve regime flips — Past curve regime changes: every flip with its time, what it flipped from, and how the session closed.
FX momentum board — FX momentum scorecard: seven major currencies scored against the basket. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.
Volatility board — Implied volatility board: VIX and the other vol gauges with their one-year percentile. Newest reading plus past boards. Market data: answers with numbers on Pro and Ultimate.
Inflation — Every US inflation measure on one axis: headline and core CPI and PCE, supercore, the trimmed means, the median, the sticky and flexible splits, the CPI components, and what markets expect next. Each one comes back with its year-over-year reading plus 1, 3 and 6-month annualised, so you never have to annualise anything yourself. Also says which parts of the basket are driving the headline rate. `measures` filters by key, `history` adds the monthly series. Published statistics, so it answers on e
Jobs — Every US employment measure on one axis: total nonfarm payrolls split into private and government, the ten private sectors, federal, state and local government, ADP's own private count by sector, initial and continuing jobless claims, and JOLTS openings, hires, quits and layoffs including openings by sector. Each comes back with its monthly change plus 3, 6 and 12-month windows, in THOUSANDS of jobs. Also says which sectors drove the headline, and those parts sum to it exactly. Percentages such
Rate path — What the market is paying for US interest rates up to four years out. Two strips, kept apart because they are DIFFERENT RATES: `sr3` is sixteen quarterly 3-month SOFR futures grouped into the whites, reds, greens and blues a rates desk quotes, and `ff` is forty-eight monthly 30-day fed funds contracts. Every contract carries its implied rate now and the rate the SAME contract carried six and twelve months ago, so the gap is the market changing its mind rather than a different instrument. Rates a

Strait of Hormuz transits — Ships through the Strait of Hormuz per day, split tanker and cargo, measured by Helious from live ship tracking.
Official 17:00 Treasury closes — Official 17:00 New York Treasury yield closes per session, as Helious recorded them. Opens on Starter and above.
Economic calendar — Economic releases with forecasts, prior values and the actual once it prints, plus Fed speakers and auction times. Defaults to yesterday through the next 7 days; widen days_back and days_ahead to see more, or filter to one country like US, EU, GB or JP.
Economic series Helious tracks — Every US economic data series Helious tracks (CPI, payrolls, GDP and so on) with its slug for get_series.
One economic series in depth — One economic data series: the latest print, the forecast, the surprise in standard deviations, and the history.
Treasury auction results and tails — US Treasury auction results, measured by Helious at the close: the high yield, the tail against the when-issued yield, bid-to-cover against the tenor's twelve-auction average, who bought (indirect, direct, dealer), and the desk's strong, in line or weak verdict. Pass tenor to ask about one part of the curve, like 10-year-note or 30-year-bond, which is what you want for 'how did the last 10-year auction go'. The tail is the number that answers whether an auction was good or bad, and Helious is th
The Helious feed — The posts Helious publishes: scored releases, auction results, board updates, the daily brief and live squawk lines. Posts carry helious_read, the desk's plain-English line on why it matters. Depth follows your plan (1 day keyless, 7 days free, 12-24 months paid, 10 years Ultimate). Optional q filters by word; categories narrows to chosen lanes. Delayed 60 minutes without a paid key.
FOMC minutes and speech digests — The desk's read of FULL central bank documents, not headlines: FOMC minutes and Fed/ECB speeches read end to end. Each digest carries a summary, what is genuinely new versus what the market already knew, key findings with their market consequence, a hawkish/dovish committee lean, and quotes verified word for word against the source document. Minutes carry no bond or equity direction on purpose: they describe a meeting about three weeks earlier, so the desk states the lean and declines the market
The FOMC roster — Who is on the FOMC: governors and presidents, who votes this year, their lean, and their upcoming speeches.
Transcribed live events — Live events Helious transcribed in the last week (Fed pressers, briefings), one entry per event.
Your plan and how to get more — What your current tier can do, the full plan ladder, and the exact steps to tell your user when you need more: make a free account, get a key, or subscribe.

NASDAQ-100 board — The NASDAQ-100 ranked best to worst on the session: price, change and sector for every stock. Pass symbol to ask about ONE company instead, like AAPL or NVDA, and you get its price, its move on the session and where it ranks on the board today. Equities are market data: live on Pro and Ultimate, upgrade steps instead of numbers below.
Fed rate cut and hike odds — The odds of a Federal Reserve rate cut or hike at each remaining FOMC meeting, priced from fed funds futures. THIS IS THE TOOL for 'what are the odds of a cut in September', 'is the Fed cutting', 'what is priced in for the next meeting' or 'how many cuts this year'. Gives the probability per meeting, the implied effective rate after each one, and the total move priced across the whole path. Computed by Helious from settlement prices against the effective fed funds rate, not the target midpoint.
Why the market is moving — START HERE for any 'why is the market doing this' question. One call gives the whole cross-asset board (equities, the Treasury curve, FX, volatility, commodities), every scored economic release behind it, and the Helious desk's read on what is actually driving the session: whether it is event-driven, flow-driven or quiet, the evidence that read rests on, and the regime yields and stocks have actually been trading in. Use this before the individual board tools: it saves five calls, and it charact
Mega-cap earnings dates and EPS — US mega-cap earnings: when a company reports, whether that date is confirmed or still an estimate, whether it prints before the open or after the close, the consensus EPS, and once it lands the reported EPS with the beat or miss. Pass symbol for one name, like AAPL. This is the tool for any question about a company's earnings date or EPS.
