Trading session local time · Europe/Oslo
Session hours and the settlement cycle are compiled by Finance Foundation from the venue’s own published trading calendar. These are exact and change-prone — an extended session or a moved auction dates a figure like this quickly — so each row below carries what two independently maintained open calendars say about the same venue. Verify against the exchange before relying on any of it operationally. Sources.
Two independently maintained open calendars return the same hours as we hold. Cross-check from exchange_calendars (Apache 2.0) and pandas_market_calendars (MIT); neither endorses this site.

Operating MIC vs segment MIC per ISO 10383: the operating code identifies the exchange, segment codes identify its individual order books, growth markets and derivatives venues. Every code was checked line by line against the official ISO 10383 registry file (SWIFT is the registration authority) — codes that were expired or belonged to a separate operating venue were rejected.
