Oslo Børs – removal of member preferencing for all Millennium orderbooks, all instruments – from May 15, 2020.

Oslo Børs has discovered a functional issue with how the trading engine is matching iceberg orders when member preferencing is enabled. The problem leads to a potential breach of the pre-trade transparency waiver for Iceberg orders that we currently hold as a requirement under MiFID II, and must be amended in order to make sure we comply with the transparency requirements. However, fixing the problem will take some time and requires programming work that could possibly extend right up to or beyond the time for the Optiq-migration in November. Migrating to the new system will solve the issue. Oslo Børs has therefore decided not to make the changes in the current matching engine, but instead opted for an alternative solution in the short period until migration, in order to remain compliant with the regulation. This alternative solution means we will turn off member preferencing for all orderbooks in the Millennium Production environment for all instruments, starting on May 15, 2020. In the CDS environment the change will be active on May 5, 2020.
