The Closing Auction Session, a commonly used trading mechanism in securities markets, enables execution at the closing price. During a closing auction, market participants interested in trading at the closing price can enter buy and sell orders. These orders are collected and interact in the trading system to determine a consensus closing price for each security, at which the orders are executed.

The Closing Auction Session begins immediately after the completion of the Continuous Trading Session and typically lasts for approximately 8 to 10 minutes.
