Nasdaq gets ready to determine the Nasdaq Official Closing Price for each asset as the trading day ends. This effort aims to determine a price that results in the greatest number of customers and sellers being matched. In order to do this, three major categories of trade requests are used as the market closes. Investors who want to trade at particular prices can make two orders, referred to as Limit on Close (LOC) and Market on Close (MOC) orders. These investors look out for the day’s closing price while placing MOC orders. A “limit” is the name given to this set price. Imbalance-Only Orders are the third trading type (IO). Various companies that are National Association of Securities Dealers members conduct IO trades specifically to promote trading.
