NOII

Order imbalance information about the opening and closing crosses on the Nasdaq disseminated to market participants prior to executing the crosses. The Net Order Imbalance Indicator (NOII) shows the true supply and demand for a stock, based on actual buy and sell orders, 10 minutes before market close and five minutes before market open. The NOII therefore enhances market participants’ trading ability and helps them spot new trading opportunities. It also increases market transparency by supplying users with detailed information about opening and closing orders, as well as likely opening and closing prices for a security.
