The Official Closing Price for all instruments traded on ISE Xetra® is determined as follows:
- If an instrument is traded in the closing auction the auction price will be the Official Closing Price (with a cut off time of 17.00 Irish time for potential extended conclusion of closing auctions).
- If there are trades during the opening auction or during continuous trading for an instrument on the day, but the instrument does not trade in the closing auction or the closing auction is extended beyond 17.00, the Last Traded Price previous to 16.30 will be the Official Closing Price.
- If there are no trades for an instrument on a particular day, the Official Closing Price defaults to the previous day’s Official Closing Price.
This price determination will occur at 17.00 Irish time and is published via the Deutsche Börse Consolidated Exchange Feed within 5 minutes of determination for all instruments which have traded on the day.
