Which detail is true about the opening period’s function?

• A. Closes trading for the day
• B. Opens continuous trading, determines the opening price and executes orders in accordance with matching rules.
• C. Sets only the reference price
• D. Executes only limit orders

Answer: (B)

The opening period is about price discovery and starting the day’s trading. It launches continuous trading, determines the opening price, and executes orders according to the exchange’s matching rules. This means the opening phase brings together buy and sell interest to find where they agree on a price, and from there normal trading continues with the usual matching process. It’s not about closing the day, it doesn’t limit itself to a reference price, and it includes all types of orders that are eligible for opening matching, not only limit orders.
