The price at which a stock begins continuous trading, set by the pre-open auction.
Not the first trade of the day in the ordinary sense — it is the outcome of a fifteen-minute auction most traders never read about.
The 9:00–9:15 window in which the NSE collects orders and computes a single opening price.
Orders collect until 9:08, match until 9:12, and everyone who trades gets the same equilibrium price.
