If the Northbound Daily Quota Balance drops to zero or the Daily Quota is exceeded during the opening call auction session, new buy orders will be rejected. However, as order cancellation is common during opening call auction, the Northbound Daily Quota Balance may resume to a positive level before the end of the opening call auction. When that happens, SEHK will again accept Northbound buy orders.

If the Northbound Daily Quota Balance drops to zero or the Daily Quota is exceeded during a continuous auction session, no further buy orders will be accepted for the remainder of the day. It should be noted that buy orders already accepted will not be affected by the Daily Quota being used up and will remain on the order book of SSE and SZSE respectively unless otherwise cancelled by relevant SEHK Participants.
