  2. Order matching method
    • Periodic order matching: The method compares buy orders and sell orders of stocks in a specified time. The executed price is the one that reaches the largest transaction volume. If more than one price satisfies the above condition, the price which is similar or closest with nearest matching order price will be selected.
    • Continuous order matching: The method compares buy orders and sell orders immediately when they are inputted into the trading system.
  3. Matching principles
    • Price Priority: Buy orders at higher price will take precedence. Sell orders at lower price will take precedence.
    • Time Priority: In case buy or sell orders at the same price, those which entered into the trading system earlier will take precedence.
