Stock Opening Auction

?

First Official Trade of the Day

The Opening Auction tool captures the first official trade of the regular session—executed as a single auction by the designated market specialist. It reflects the accumulation of buy and sell orders held for the open and executed at a single equilibrium price. This tool is valuable for traders analyzing early price discovery, large opening volume spikes, and market sentiment before regular hours continuous trading. Ideal for studying high-impact trades that bypass pre-market activity and kick off the trading day.
