02 Jan 2014

Hong Kong Exchanges and Clearing Limited (HKEx) will introduce Mini Hang Seng Index (Mini HSI) and Mini H-shares Index (Mini HHI) Futures as well as its Block Trading Facility (BTF) to its After-Hours Futures Trading (AHFT) session starting on Monday, 6 January 2014.

HKEx’s AHFT session is from 5 pm to 11 pm and currently includes Hang Seng Index (HSI) Futures and H-shares Index (HHI) Futures.

The BTF does not apply to mini index futures contracts trades now and will not apply to them in AHFT.

Block trades will not be exempt from AHFT’s +/-5 per cent price limit, and block trades or block trade-related adjustments will be rejected if there is insufficient collateral in the Participant’s account during after-hours trading because banking facilities will not be available for special block trade margin call during AHFT. The attached table shows how the BTF will operate from 6 January 2014.

Block trades will be rejected if Participants cannot deposit SBTM within 1 hour.	If the margin fund maintained with the Clearing House is insufficient to cover SBTM, block trades will be rejected automatically without SBTM call in AHFT Session as there are no banking facilities during AHFT Session for the Clearing House to collect SBTM.

*	If the execution price of a block trade deviates from the prevailing market price such that an intra-day variation adjustment would have been triggered (i.e. currently 25% of the margin rate), the Clearing House will collect SBTM for such block trade from the concerned Clearing Participant.
