Available Order Types
The following order types are available through Aristo. For information on HKEX trading sessions, order types and matching rules, see the HKEX Trading Mechanism.
An at-auction order is a market order entered without specifying a price during the Pre-opening Session or Closing Auction Session. The order will be matched at the final Indicative Equilibrium Price (IEP).
At-auction orders have priority over at-auction limit orders. Orders are then matched according to price and time priority.
Any unfilled at-auction orders submitted during the Pre-opening Session or Closing Auction Session will be cancelled automatically.
Please note that the execution price is not known when the order is entered and may fall outside or differ significantly from your expected price range. Aristo Securities Limited reserves the right to sell the relevant securities to cover any cash shortfall.
