Order Type in Auction Period
At-auction limit order
An at-auction limit order is a buy order or a sell order in Pre-opening Session and Closing Auction Session, with a specified price input. When the specified price is (in the case of a buy order) equal to or higher than final IEP*, or (in the case of a sell order) equal to or lower than the final IEP*, the order will be matched at the final IEP* (subject to the HKEX order automatic matching result). Multiple day order is not allowed for At Auction limit order.
In Pre-opening Session, any unmatched at-auction limit order would be converted to a limit order and carried forward to the Continuous Trading Session if it is within the price limit. In Closing Auction Session, any unmatched today order will be unexecuted at the end of the trading session.
At-auction order
An at-auction order is a buy order or a sell order in Pre-opening Session and Closing Auction Session, with no specified price input. The order will be matched at the final IEP* (subject to the HKEX order automatic matching result). Please note that the execution price of At-auction Order may substantially deviate from the stock price at the time you submitted the order.
Any unmatched order will be unexecuted at the end of the trading session.
* Indicative Equilibrium Price (IEP) refers to the price where the maximum number of shares can be traded if order matching occurs at that time. Final IEP will be the opening price of the relevant stock in Pre-opening Session, and closing price in Closing Auction Session. Please refer to the HKEX website for detailed definition.
