Information - impact of the Single Order Book on My Euronext services

Single Order Book implementation the 14/01/2009

The Single Order Book consists of one single trading line for securities listed on several Euronext Cash marketplaces (multi-listed securities). The market where all orders are concentrated on a single trading line is called ‘Market Of Reference’

Impact on My Euronext services

The portfolios, watchlists and alerts will be updated in the run of the morning the 14/01/2009 to reflect this change.
Thus, some of the instruments included in your Watchlists and Alerts may correspond to another market of reference after the change.
The multi-listed instruments included in the portfolios will be valuated using the price of the Market of Reference.
In the case of a portfolio including a multi-listed instrument on 2 lines (2 different markets), the line that does not correspond to the Market of Reference will be frozen and indicated by an orange background. You will have then the possibility to remove it after adjusting if necessary your position corresponding to the Market of Reference.

You can download the list of Multi-Listed securities with corresponding Market of Reference
