What is showing in depth between 9.01 am to 9.14 am,

Hello,

The time period of 9am to 9.14am is the Pre-Open market. The purpose of this market is to calculate the Opening price(also called the Equilibrium price) for the day - for stocks as well as the index. During the first 8 minutes of this Pre-Open market, you will see the Bid-Ask prices and quantities fluctuating in order to search for a fair Opening price.
