Stock Market Special Trading Session Details & Timing
Ever heard about a “special trading session” and wondered what makes it different from a regular stock market day? Whether you’re a seasoned trader or a beginner, understanding the idea of a stock market special trading session is important. These sessions can pop up for several reasons—Union Budget day, market system testing, festivals, or extraordinary events. This guide breaks down what these sessions are, why they happen, their timings, how they affect trading, and answers every real question beginners and pros have.
What is a Stock Market Special Trading Session?
A stock market special trading session is an additional trading session scheduled outside the existing market hours. It can occur on weekends, holidays, or at unique timings to ensure continuity of business, testing market systems or reacting to events that are critical.
These sessions can be:
- A full trading day (like on a Saturday for an important budget event)
- A short “mock” session for systems testing
- A special slot for things like IPOs or annual festive rituals
Both NSE (National Stock Exchange) and BSE (Bombay Stock Exchange) conduct these sessions periodically.
Why Are Special Trading Sessions Held?
Here are the main reasons:
- Union Budget Days: When the government budget is announced on a weekend, markets can be open specifically for announcements and reactions.
- System/Contingency Drills: Exchanges test the robustness and readiness of their online systems. This improves security and performance if problems happen in future.
- Festive Occasions: Special live trading sessions, like the Diwali “Muhurat” session, let investors start the financial year with positivity.
- Extraordinary Events: Sometimes, after big policy changes or global emergencies, the market may run a special slot to restore or maintain confidence.
Recent Examples of Special Trading Sessions
Union Budget Days
When the Indian Union Budget is presented on a non-trading day (like Saturday), the NSE often opens a special trading session.
Example:
On February 1, 2025 (a Saturday), the NSE held a full trading session from 9:15 AM to 3:30 PM to facilitate market reaction to the budget. All segments (Stocks, F&O) followed standard timings, but settlement was deferred due to the weekend.
Contingency/Mock Trading Drills
To ensure system reliability, NSE often schedules drills on select Saturdays. These are known as NSE special trading sessions or mock drills.
- These sessions help both brokers and investors test systems and are key for backup preparedness.
- Brokers can check their infrastructure for glitches so real trading runs smoothly during main hours.
Festive or Ritual Sessions
A perfect example is the annual Diwali Muhurat Trading, a one-hour session considered auspicious for new investments.

Timings and Structure: What to Expect
A special trading session today may follow slightly altered timings, but often tries to match regular hours so traders don’t get confused.
