This extended the auction call period by 5 minutes, triggered when the matching process would have resulted in an execution price exceeding a pre-determined percentage from the most recent automated execution.
Price Monitoring Extension
The auction call period has been extended in this security by 5 minutes.
Auction call extensions give London Stock Exchange electronic order book users a further opportunity to review the prices and sizes of orders entered in an individual security's auction call before the execution occurs. A price monitoring extension is activated when the matching process would have otherwise resulted in an execution price that is a pre-determined percentage above or below the price of the most recent automated execution today.
The applicable percentage is set by reference to a security's Millennium Exchange sector. This is set out in the Sector Breakdown tab of the Parameters document at www.londonstockexchange.com/tradingservices
