Hong Kong Exchanges and Clearing Limited shortens the gap between day and night trading sessions for futures. Night trading during British and American holidays can proceed as usual.

HKEX announced that the optimization measures for the T+1 session will officially be launched on July 20, 2026 (Monday). The optimization measures include three major points: stock index products will be open for trading in the T+1 session on common holidays in the UK and the US; the market closure time between the normal trading session and the post-closing trading session ("T and T+1 sessions") will be shortened from 45 minutes to 30 minutes; designated stock index futures contracts will have their price limit in the post-closing trading session ("T+1 session") expanded from 5% to 6%. The above optimization measures will help improve the accessibility of the derivatives market, enhance the trading continuity between the T and T+1 sessions, and increase the flexibility of stock index futures trading, thereby promoting more effective price discovery. The list of stock index futures with expanded price limits of 6% in the T+1 session and the starting time of the T+1 session divided by product group are as shown in the following diagram: [diagram not included]
