For CAS-eligible stocks, the closing price will be determined through an equilibrium price mechanism based on the maximum executable volume, minimum unmatched quantity, and proximity to the reference price.     

• Note: Equilibrium Price Mechanism means the exchange finds a single price at which the maximum number of buy and sell orders can be matched during the auction.
• Simple example: Instead of simply calculating the average traded price during the last 30 minutes, buy and sell orders will be brought together in the closing auction to discover the closing price.
