What the status labels mean

Live: Retrieved from the source within its refresh interval.: Retrieved from the provider within its refresh interval; for quotes, the last trade is under 30 minutes old.
Delayed: Official daily publication, not an intraday value.: Retrieved from the provider, but the value is an official end-of-day publication or an older quote. Check the as-of date.
Cached: The source could not be reached. Showing the last data retrieved successfully.: The provider could not be reached, so the last successfully retrieved data is shown with its original retrieval time.
Sample data: Illustrative sample values. This is not real market data.: Illustrative values used for stocks and ETFs only when no quote provider is configured. They are not market data and carry no timestamp. Off by default; turn them on with ENABLE_SAMPLE_DATA=true. Rates, yields and news are never simulated.

A Stale warning appears when an observation is older than expected for its publication schedule (for example, a daily rate not updated for five days).
