Auction & Execution

The execution price in a call auction shall be determined according to the following principles:

(2)  the price which allows all the buy orders with a higher bid price and all the sell orders with a lower offer price to be executed;

(3)  the price which allows at least all the buy orders with identical price or all the sell orders with identical price to be executed.

The execution price in a continuous auction shall be determined according to the following principles:

(1)  where the highest bid price is identical to the lowest offer price, such price shall be taken as the execution price;

(2)  where the bid price is higher than the lowest offer price currently available in the central order book, such lowest offer price shall be taken as the execution price;

(3)  where the offer price is lower than the highest bid price currently available in the central order book, such highest bid price shall be taken as the execution price.
