Which statement best describes the opening period?

• 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)

Opening period is the phase at market start when trading resumes and the opening price is established through the matching of orders. The best description captures that continuous trading starts, the opening price is determined, and orders are executed according to the exchange’s matching rules. This reflects both price discovery at the open and the actual execution of orders under the applicable rules. The other statements miss key parts: one describes only closing or end-of-day activity, another implies only a reference price is set, and another suggests only limit orders are executed. In reality, the opening period involves initiating active trading, discovering an opening price, and matching and executing a range of orders according to the rules.
