During the Opening Auction Call Phase, if the order book is crossed, the indicative auction price, auction volume and auction surplus (volume and side) will be displayed. If the order book is not crossed during the Opening Auction Call Phase, the best bid limit and the best ask limit with their respective volumes will be displayed.

Once the Opening Auction concludes, Continuous Trading will commence.

Please note the following special procedures:

• Orders entered with trading restriction “OAO” (Opening Auction only) will only be considered in the first auction of the exchange trading day, i.e. in the first price determination for the shares. Orders entered with trading restriction “AOO” (Auction only) will be considered in the opening auction, the intraday auction and the closing auction.
• The usual safeguards in Xetra (MIC: XETR) will also be applied in the Opening Auction. Therefore, a volatility interruption may occur following the Auction Call Phase.
• The intraday auction starts at 13:00 CE(S)T and takes at least two minutes.
• If an exceptional number of orders is executed in any one auction, it may lead to delays in processing confirmations.
