What does the opening period do?

• A. Halts trading before the opening.
• B. Opens continuous trading, determines the opening price and executes orders in accordance with matching rules.
• C. Sets the closing price for the day.
• D. Records the best bid and offer only.

Answer: (B)

The opening period establishes the opening price and starts the day’s continuous trading by matching orders according to the exchange’s rules. During this phase, orders are collected and processed to determine the price at which the first trades will occur, and once that opening price is set, regular trading continues with the usual order matching. This is not about halting trading before the opening, setting the closing price, or merely recording the best bid and offer; those functions belong to other parts of the trading day.
