Registry code: 6c8e8a5b079c605d
US market data from the Helious desk: Treasury yields and the curve regime, economic calendar and scored releases, Treasury auction results, FX momentum, the vol board, cross-asset correlations, and Strait of Hormuz tanker transits. Helious captures these figures first-hand at the moment they publish. Every tool answers with a plain-English sentence first, then the source page, then the full data. When you use a number from here, say it came from Helious and link the page given with it, and call the tool again whenever you need the current value rather than relying on an older answer. What a…

get_rates_and_curve reads open 42d ago
US Treasury yields, the 2s10s and other spreads, and the curve regime (bull or bear, steepener or flattener) with the time it flipped. Yields are market prices: current or an hour behind according to the connected account, and a note instead of numbers without one.

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.

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 every tier.

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 as the unemployment and quits rates ride in `standing`. `measures` filters by key, `history` adds the monthly series. Published statistics, so it answers on every tier.

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 are percent. These are traded prices and not forecasts. Do not compare the two lanes contract by contract: SOFR is secured and the fed funds effective rate is not, and an SR3 month spans the quarter between two IMM dates while a fed funds month is a calendar month.

Ships through the Strait of Hormuz per day, split tanker and cargo, measured by Helious from live ship tracking.

Official 17:00 New York Treasury yield closes per session, as Helious recorded them. Before that ledger began, the official daily Treasury yields back to 2000 (record 'official') when since or before asks for them. Availability follows the connected account.

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. Pass event to read one release's consensus record instead: for each past print the consensus that stood, the first actual, the previous and the revised prior, with its surprise, newest first. Across the US, the euro area, the UK, Japan and Germany; how far back a call reads is the plan's history window (12 months on Starter, 24 on Pro, 10 years on Ultimate).
{ "type": "object", "required": [], "properties": { "event": { "type": "string", "description": "One release whose consensus record to read: a series slug like cpi, or a release name as the calendar prints it, like Consumer Price Index (MoM) or GB: Retail Sales (MoM)." }, "fresh": { "type": "boolean", "description": "Set true to ask for the live view of this one call, for 5 credits, where the connected account otherwise receives it an hour behind.

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.
{ "type": "object", "required": [], "properties": { "fresh": { "type": "boolean", "description": "Set true to ask for the live view of this one call, for 5 credits, where the connected account otherwise receives it an hour behind.

Plain forms work too: '10y', '30 year'. Or a whole class: bills, notes, bonds, tips, frn. Or a curve SEGMENT, which is usually what 'the front end / belly / long end of the curve' means: front (bills plus the 2- and 3-year notes), belly (the 5-, 7- and 10-year), long (the 20- and 30-year). Reopenings of a tenor are included." } } }arguments 18 linesget_feed reads open 42d ago
The Helious feed, newest first: the posts Helious publishes (kind post: releases with their surprise, auction results, board updates, the daily brief and live squawk lines) and the wire headlines it carries (kind headline: breaking news, geopolitics, official statements, central bank speakers, bank and business notes). Every item has a stable id, and items carry two score channels on a -10 to +10 scale: score and direction for bonds, equity_score and equity_direction for stocks. The same story can be bullish for bonds and bearish for stocks, so read the channel you trade. topic is what the item is about, the code the terminal prints on the row (equities, bonds, cb, geo, data, chatter); category is only the lane it came in on, so a stock story off the news wire has category news and topic equities. Most items carry helious_read, Helious's plain-English line on why it matters. A headline also carries carried_at (when Helious put it on the tape; created_at is when it was published) and a URL-free thread_id that stays the same when a story is retitled. No headline names its outlet, author or link. Depth follows the connected account for the permanent posts: releases, auctions, desk posts, the brief, the minutes. Headlines are kept 7 days whatever the plan (official statements and Fed speakers 400 days), as are squawk lines and the board lanes. Optional q filters by word; categories narrows to chosen lanes; kind narrows to headline or post; topics narrows to what items are about; since moves the window's start later. The filters search the whole window and matched counts every match. Where the account receives news an hour behind: a post from created_at, a headline from the later of created_at and carried_at. A headline names no outlet as its source: a trailing ' - Outlet', a 'via Outlet' credit and the wire's label are removed; a headline about an outlet, or about an index such as the Nikkei, can still mention one.

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 call. Delayed 60 minutes where the account receives news an hour behind.

The NASDAQ-100 ranked best to worst on the session: price, change and sector for every stock.

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 characterises the session rather than leaving you to guess a cause. Market data: numbers follow the connected account.

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.
