Market order is an order to buy/sell securities at the prevailing bid/ask price of the securities. The final execution price may differ from the nominal price at the time of order placement, especially for illiquid stocks and/or at the beginning of a morning and afternoon trading session due to orders accumulated during pre-market opening that need to be handled.
To help you better manage risk, the Bank will submit your market order to the market with one try only by matching it up to 10 best price queues at Hong Kong Exchanges and Clearing Limited (i.e. the prevailing best queue and up to the 10th queue at 9 spreads away at the time when the market order is processed) and up to a maximum of 20 spreads from the prevailing nominal price at the time your order is processed. Any unfilled quantity of your market order as a result of the above mechanism will automatically be cancelled right away. You are advised to check the order status to see if the market order has been fully executed or cancelled. If your order is not fully executed, you may wish to place another order.
