Market Data Methodology

The market strip provides delayed reference prices for context. It is not an exchange feed and it is not investment advice.

Providers and cadence

• US stocks, ETFs and available indices: public Nasdaq quote pages, cached for up to five minutes.
• Cryptoassets: CoinGecko public market data, cached for up to two minutes.
• Foreign exchange: European Central Bank daily reference rates; cross-rates are calculated from the EUR reference table.

The strip labels the assembled feed as delayed. Its hover disclosure gives the UTC assembly time for the cached snapshot. Provider exchanges may report different timestamps or prices.

Instrument labels

Share prices for tracker funds are labelled as ETFs. For example, SPY is shown as “S&P 500 ETF” and GLD as “Gold ETF”; neither is represented as the level or spot price of its underlying benchmark. Percentage moves belong to the displayed instrument.

Failure behaviour

A quote that is invalid, unavailable or non-positive is dropped rather than shown. If no usable feed is available, the strip does not render at all. Prices are assembled snapshots and should be read as context, never as execution data.
