NSE India & BSE India Introduce Pre-Open Session in Equity Derivatives: What Traders Need to Know

On December 8, NSE India and BSE India introduced a Pre-Open Session for the Equity Derivatives segment. The twist is that not all expiries are eligible.

🔹 What’s Affected

  • Index & Stock Futures (not Options)
  • Pre-open applies to current-month contracts
  • Next-month futures become eligible during the last five trading days of the current-month expiry
  • The session is divided into three: Order Entry → Order Matching/Confirmation → Buffer Period

🔹How Swaps Monitor Helps

  • Enhanced Trading Hours Centers with clear segmentation
  • The “Functionalities” feature in our Trading Hours data indicates allowed actions in each sub-session
  • New: “Pre-Open Eligibility Day” in our Expiry Dates data shows exactly when each contract becomes eligible

These enhancements ensure our customers know exactly when each contract is eligible for pre-open and what activities are allowed during each session.

Market adjustments can be complex — we make them simple to navigate.

BME’s European-Style Cash-Settled Stock Options: A New Alternative 

Earlier this year, BME introduced the first standardized European-style cash-settled stock options in Europe—an important milestone for the region’s equity derivatives landscape. 

By combining European-style exercise with cash settlement, these contracts remove early-exercise risk and eliminate the operational issues arising from physical share delivery at expiry.  

As new alternatives emerge, we at Swaps Monitor help market participants stay current with the key components of smooth trading—holidays, trading hours, and expiry dates. Our forward-looking data gives the clarity they need to adjust quickly and operate with confidence as markets evolve.

📢 CME Halt on Thanksgiving Highlights Trading Schedule Complexities

On Thanksgiving Day (November 27), CME markets experienced trading halts, further disrupting an already adjusted holiday trading schedule. While many assume holidays mean full market closures, several CME products were scheduled for trading on that day for the trade date of November 28.

The Hidden Market Impact of Clock Changes: Trading Hours Adjustments
