What are the trading hours for a stock on the listing day after its IPO?
On the day a stock is listed following an IPO, it begins trading on the exchanges at 10:00 AM and continues until 3:30 PM. However, there is a pre-open session between 9:00 AM and 10:00 AM, during which the following activities take place:
| Timings | Activity |
| 9:00 AM to 9:35 AM | Only limit orders for new listings (IPOs) and re-listed instruments can be placed, modified, or cancelled. |
| 9:35 AM to 9:45 AM | Only limit orders can be placed, modified, or cancelled. However, the system will randomly close all pending orders between 9:35 AM and 9:45 AM. |
| 9:45 AM to 9:55 AM | The exchange matches the orders to determine the opening price of the stock. |
| 9:55 AM to 10:00 AM | Buffer period to ensure a smooth transition into the normal trading session. During this time, orders cannot be placed, modified, or cancelled. |
| 10:00 AM to 3:30 PM | Normal trading hours. Orders can be placed, modified, or cancelled. |
