NYSE/Euronext has since January worked with a single order book, i.e. the share orders placed for companies with several European listings are consolidated to increase liquidity. The option for a second or third listing remains, but the trade in the share is centralised. The administration of all transactions on the three stock exchanges is performed by Euroclear.

Euronext considers consolidation as the final step in the process of integrating the Paris, Brussels and Amsterdam stock exchanges (Het Financieele Dagblad dated 15 January 2009).
