Trading Session Selection Guide

1. Continuous Trading Session (CTS)

When you select this option:

  • Orders will be submitted as Enhanced Limit Orders

  • Orders will participate in the continuous trading session for matching

  • At the end of the CTS, for securities eligible for closing auctions, unexecuted buy orders that do not exceed their security's upper price limit and unexecuted sell orders that are not below their security's lower price limit will be transferred into the closing auction session. These transferred orders will be treated as At-auction Limit Orders.

2. Auction, Continuous Trading Session (AUC+CTS)

When you select this option, orders will be matched as follows:

A. Orders Submitted During a Pre-opening Session

  • Will participate as At-auction Limit Orders

  • After the pre-opening session, unexecuted orders that do not deviate from their nominal price by 9 times or more will be automatically entered into the continuous trading session as regular limit orders in queue.

B. Orders Submitted During Continuous Trading Session

  • Will participate as Enhanced Limit Orders

  • At the end of the CTS, for securities eligible for closing auctions, unexecuted buy orders that do not exceed their security's upper price limit and unexecuted sell orders that are not below their security's lower price limit will be transferred into the closing auction session. These transferred orders will be treated as At-auction Limit Orders

C. Orders Submitted During a Closing Auction Session

  • All limit orders will participate as At-auction Limit Orders

  • Orders will either expire after the closing auction session or continue to the next trading day if they are not expired

By selecting the trading session that suits your trading strategy, you can participate more effectively in the Hong Kong securities market.
