Field notes
The documented endpoints distinguish exchange status from settlement calculations, with status responses able to report open, closed, or lunch-break conditions and the next opening or closing time. Settlement examples join a market calendar with a cash-leg calendar, and the response includes the calendars used and skipped-day reasons. The page also describes source and verification information for calendars, with corrections logged at /v1/changes.
