Hi welcome to or

Here we will discuss everything you need to know about order placement and its time.

Pre-open session orders

Orders placed before the opening of the market (09:15 AM) are called pre-open session orders. Pre-open session is between 9.00 AM to 9.15 AM. This 15 minutes session involves 3 slots


  • 9.00 – 9.08 AM-Order collection period
  • 9.08-9.12 AM – Order matching and trade confirmation period
  • 9.12-9.15 AM

Pre-market Orders:

NSE started this pre-open session to minimize the volatility of securities during the market opening every day.

  1. 9.00 – 9.08 AM (Order collection period)-In this slot of 8 minutes, 9.00 – 9.08 AM (Order collection period), you can place, modify or cancel your orders.You can place limit orders/market orders.
  2. 9.08-9.12 AM  (Order matching and trade confirmation period)-In this period 9.00 – 9.08 AM (Order collection period), on the basis of orders received in slot 9.00 – 9.08 AM (Order collection period), the exchange determines the Opening Price and confirms orders that matches the price. The remaining orders unconfirmed orders that were not having its buyers or seller are moved to market session (after 9.15 AM) .
  3. 9.12-9.15 AM – This is a buffer period to facilitate transition from pre-open to normal market session.
