You can trade IPO-listed stocks from 10:00 AM to 3:30 PM on their listing day. However, there is a pre-open session between 9:00 AM and 10:00 AM, during which the following activities take place:
|
|
Timings | Activity |
| Order entry period | 9:00 AM to 9:35 AM | You can place, modify, or cancel only limit orders for new listings (IPOs) and re-listed instruments. |
| 9:35 AM to 9:45 AM |
You can place, modify, or cancel only limit orders. The system will randomly close all pending orders at any time between 9:35 AM and 9:45 AM. Orders are executed immediately when the order entry period closes. For example, if the system closes pending orders at 9:40 AM, your order will be executed around 9:40 to 9:41 AM and will not wait until 9:45 AM for execution. |
|
| Order matching and trade confirmation period | 9:45 AM to 9:55 AM | The exchange matches your orders to determine the opening price of the stock. You cannot place new orders during this time. |
| Buffer period | 9:55 AM to 10:00 AM | The system prepares for normal trading. You cannot place, modify, or cancel orders during this buffer period. |
| Trading hours | 10:00 AM to 3:30 PM | You can place, modify, or cancel orders normally during regular trading hours. |
