Amendments to segments, sectors and period rules
ITBB segment/sector changes and IOB sector changes are detailed in full in Appendix 1. No securities will be migrated as a result of the scheduled sector deletions.
New period rule ‘IBC2’ will be introduced to the sector default schedule at 15:20 for all ITBB sectors with price monitoring controls (IBHL, IBLL, IEUL, JEUL, JPL1, INEH, INEL, JNEH, JNEL, IEUH). If price monitoring controls are activated during this period then the security will move immediately into the closing auction. This change will bring the ITBB into line with the Exchange’s other trading services.
New period rule / DescriptionIBC2 / INT.BB.EQ ODR.TRDG.2
The closing price calculation for all ITBB segments will continue to be determined by the uncrossing price in the closing auction. In the event that an uncrossing does not occur the closing price will now represent the price of the last automated trade in that security (UT/last AT).
