The Single Order Book (SOB) project will consolidate trading on a single line in the central order book for securities listed on all Euronext Cash marketplaces (with the exception of Lisbon*). The SOB concept has been one of the cornerstones of the Euronext consolidation process.
Trading will be enhanced through the enlarged order book with the adoption of a single code for all instruments (ISIN code) and the removal of so-called ‘Euronext codes’. Access to the market will be simplified and streamlined, as an instrument will only be tradable using its ISIN code.
The SOB is being implemented in conjunction with the ongoing Euroclear Settlement of Euronext-zone Securities (ESES) project.
*Lisbon is not included in the scope of the SOB, since Interbolsa is not part of the Euroclear group & therefore not part of the ESES project.
