Refresh rate: Intraday 1-minute bars fetched every 60 seconds on weekdays. Every 5 minutes on weekends (markets closed - data is stale by design). Sparkline history seeded once at startup using 5-day daily closes.

Limitations: Yahoo Finance does not guarantee real-time accuracy. Data may be delayed by up to 15 minutes for some instruments. The public API has no SLA and may be throttled or temporarily unavailable without notice. Yahoo Finance does not provide a VIX front-month futures ticker (VX=F) reliably - we source that indicator from CNN instead. Foreign exchange rates are sourced from Twelve Data (see Section 02).

Limitations: FRED data is official but published with a one-business-day lag for most series. It does not provide intraday data - yields shown are the prior day's official closing value until the next release.

FRED terms: fred.stlouisfed.org - Legal · Data is in the public domain and free to use per FRED's copyright policy.

Provider: CNN / Warner Bros. Discovery
Access: Public data endpoint, server-side only

Data supplied:

• Fear & Greed Index - CNN's composite sentiment score (0–100), computed from seven equally-weighted sub-indicators: S&P 500 momentum, NYSE stock price strength, NYSE stock price breadth, CBOE put/call ratio, VIX vs its 50-day moving average, junk bond demand (HYG), and safe-haven demand (Treasury vs equity performance)
• Fear & Greed rating - the categorical label: Extreme Fear, Fear, Neutral, Greed, or Extreme Greed
• Put/Call ratio - raw CBOE equity put/call ratio derived from the put_call_options data series (e.g. 0.66 = 66 puts per 100 calls)
• VIX 50-day moving average - the smoothed volatility baseline used in CNN's Fear & Greed calculation, displayed on the VIX 50MA gauge

Refresh rate: CNN updates their Fear & Greed data several times per day as market conditions change. The dashboard polls the CNN endpoint every 15 minutes and broadcasts the latest values to all connected browsers instantly via WebSocket.

Limitations: CNN does not provide a formal public API agreement for this endpoint. The data is used in accordance with fair use for informational display. CNN's Fear & Greed Index is a proprietary composite - the underlying methodology is described by CNN but the exact weightings and normalisation may change at any time. The dashboard displays this data as-is; we do not alter or reweight the composite.

Data supplied:

• High-impact US economic events - Non-Farm Payrolls (NFP), CPI, FOMC interest rate decisions, GDP, PCE, PPI, Unemployment Rate, Initial Jobless Claims, Retail Sales, ISM Manufacturing & Services, Durable Goods, Trade Balance, Housing Starts

Four separate jobs on this site use Claude, each on its own schedule and with its own model. Everything they write is labelled as AI-written where it appears.

How the news alerts work in detail:

• Claude returns a severity score (1–10) and a concise alert message
• If severity is 7 or above, a Breaking News banner is broadcast to all connected browsers in real time via WebSocket, and the alert also appears on Markets Today until the next brief publishes
• Only news published after the server starts is classified - historic articles are never sent
• At most 5 articles per minute are forwarded to Claude, regardless of news volume

What is sent to Anthropic: Public market prices, and news headlines and summaries from Finnhub's public news feed. No user data, no personal information, and no browsing activity is ever sent to Anthropic. None of these jobs can see who is reading the site, and none of them run in response to a visit: they run on a clock whether anyone is here or not.

What it is not: none of these write predictions or recommendations, and the market temperature on Markets Today is not written by AI at all. That number is arithmetic over four measurements, so the same inputs always give the same result. The AI writes the words around it, not the number.

Which venue does a US price come from?

None of them, and all of them. A US stock or index price is consolidated: the same security trades on many venues at once, and the quote you see is assembled from all of them rather than taken from one exchange. So a price on this dashboard is not "the NYSE price", it is the national price, whichever venue the last trade happened on.

That list of venues grew this year. The Texas Stock Exchange (TXSE) in Dallas began trading on 6 July 2026 and completed its phased rollout on 31 July 2026, when every National Market System symbol became tradable on it. It is the first national securities exchange built and headquartered in Texas, approved by the SEC on 30 September 2025 and backed by BlackRock, Citadel, JPMorgan and Charles Schwab. Corporate listings are planned for later in 2026, with IPOs from 2027.

Nothing on this dashboard changed when it launched, and that is the point. TXSE trades the same NMS symbols on the same US market hours, so its trades already flow into the consolidated prices shown here, and the market clocks answer for it exactly as they do for the NYSE. A new venue is a change in market structure, not a change in the number.

Real-time or delayed, and what each provider costs

The honest summary for US indices: genuinely real-time, tick-by-tick US equity index data is licensed from the exchanges and priced accordingly. No free provider supplies it, and any free site claiming otherwise is either delayed or passing through someone else's delayed feed. What this dashboard shows for US indices is a delayed price refreshed frequently, which is the right tool for watching how a day is going and the wrong tool for executing a trade. Crypto is the exception on this page, because it trades on venues with no consolidated tape and no license to buy, so the price really is live.

• Delays - intraday equity and commodity data may be delayed by up to 15 minutes depending on the Yahoo Finance feed. FX rates from Twelve Data may lag by up to 15 seconds. Bond yields from FRED are prior-day closing values.
• Gaps - on public holidays, some instruments may show stale prices from the last available trading session.
• Currency - all prices are displayed in the instrument's native quotation currency (USD unless otherwise shown).
• No redistribution - data sourced from these providers is subject to their individual terms of service. You may not scrape, republish, or commercially redistribute data obtained via this dashboard. See our Terms of Use Section 5 for permitted use.
• Provider changes - any of the data providers listed here may change their APIs, data formats, or terms of service at any time. If a provider becomes unavailable, the affected gauges or instruments will show their last known value or a dash (–) until service is restored.

Most financial tools are either too expensive, too fragmented, or built for a different use case. Global Markets Dashboard is purpose-built as a free real-time macro dashboard - one screen, all asset classes, no subscription.

Where does Global Markets Dashboard get its data?

From several independent providers, all called server-side: Yahoo Finance for equity indices, the US Dollar Index and extended FX, commodities, VIX and futures; Alpaca Market Data for cryptocurrency; Twelve Data for the major FX pairs; FRED at the Federal Reserve Bank of St. Louis for Treasury yields, central bank rates and spreads; Finnhub for the economic calendar and exchange holidays; and CNN Business for the Fear & Greed Index and put/call ratio. Your browser never connects to any of them directly.

Is the market data real-time?

Partly, and the distinction matters. Cryptocurrency is genuinely real time, refreshed about every 7 seconds around the clock, because crypto has no consolidated tape and no exchange license to buy. US equity indices are delayed, typically by around 15 minutes, refreshed roughly every 60 seconds on weekdays. Bond yields and policy rates come from official series published on the issuer's own schedule. Nothing here is guaranteed for time-sensitive trading.

Which providers give real-time data for US market indices?

For genuinely tick-by-tick US index data, none of the free ones. Real-time US equity market data is licensed from the exchanges themselves and priced accordingly, which is why professional terminals cost what they do. Free providers, including the ones this dashboard uses, supply a delayed feed, usually around 15 minutes behind. A free site claiming real-time US index prices is either delayed or passing through someone else's delayed feed. The practical read: a frequently refreshed delayed price is the right tool for watching how a day is going, and the wrong tool for executing a trade.

Does the dashboard cover the Texas Stock Exchange?

Yes, without needing to do anything for it. The Texas Stock Exchange (TXSE) in Dallas began trading on 6 July 2026 and completed its phased rollout on 31 July 2026, when every National Market System symbol became tradable there. US prices are consolidated across every venue, so trades on TXSE already flow into the prices shown here, and it keeps standard US market hours, so the market clocks answer for it exactly as they do for the NYSE. TXSE is the first national securities exchange built and headquartered in Texas, approved by the SEC on 30 September 2025 and backed by BlackRock, Citadel, JPMorgan and Charles Schwab. Corporate listings are planned for later in 2026 and IPOs from 2027.

Is Yahoo Finance data real-time?

Not for US equity indices. Yahoo Finance serves a delayed quote, typically about 15 minutes behind, which is what this dashboard shows for the S&P 500, Nasdaq, Dow and the other indices it covers. It is a public endpoint with no service-level guarantee, so it can also be slow or briefly unavailable. It is reliable enough to answer "how is the market doing today" and not intended for anything narrower than that.

How often does Global Markets Dashboard update its prices?

By asset class: crypto about every 7 seconds including weekends, equity indices, FX and commodities about every 60 seconds on weekdays and every few minutes at weekends when markets are shut, the economic calendar every 12 hours, and the Fear & Greed Index about every 15 minutes. Prices stream to your browser over a WebSocket, so nothing needs refreshing by hand. The full breakdown is in the refresh table above.

Is the market data free and reliable?

Free to view, and reliable within its limits. The providers are reputable, but the public and free-tier APIs used carry no service-level guarantee and can be delayed, approximate or temporarily unavailable. This dashboard is informational and should not be relied on for time-sensitive trading decisions. Where a number could mislead, the page says so rather than presenting a delayed figure as live.
