Mock trading sessions enable traders and brokers to mimic actual market conditions in a simulated environment. On 30th August, the NSE will hold such sessions in the equity markets as well as in the commodity and currency derivatives segments. It assists participants in checking the functionality of their trading systems, trying out new products or software, and conducting contingency drills to get themselves ready for surprise technical or operational glitches. Crucially, no actual fund pay-in or payout is incurred by such trades carried out during these simulation sessions, providing a risk-less testing and practicing ground.
The simulated trading session scheduled for August 30 will start with a pre-open session at 9:00 AM, after which the market will open officially at 9:15 AM. The session will then proceed until 10:10 AM, giving brokers and participants sufficient time to perform their tests and exercises. There will be a re-login window later in the afternoon from 1:30 PM through 2:00 PM, enabling participants to re-connect to the system and test for connectivity and responsiveness.

The NSE has confirmed that there shall be no new software releases during the mock trading on August 30. Market players should make sure their systems are up-graded to the latest version of the NEAT+ trading system (version 7.8.3) ahead of the retirement of the older 7.8.2 version coming up on September 6, 2025. This prevents technical hiccups during trading and smooth market operations.
All members authorised for trading in the corresponding segments get automatically qualified to attend the mock trading sessions. The participants utilise their user IDs, IP mappings, and configuration setups already present in the live environment to participate in these exercises. NSE also recommends that members thoroughly test their connectivity, set up correct system configurations, and be ready for a smooth switch-over to live markets after the simulations.
