Trading Halts Before “Open”: Understanding Exchange Sessions 

Recently, TFEX (Thailand Futures Exchange) halted Silver Online Futures before the Day Session even began. The halt occurred during the On-Open Order Execution session.  

Across 3,000+ markets we cover, there are 1,500+ session types, including: 

🔹Pre-Open 

🔹Opening/Closing Auction 

🔹Daily Settlement Period 

🔹Calculation of Opening Price 

🔹Order Matching 

🔹Enquiry 

Each session has its own rules, and order execution can happen in many of them. 

Trading activity often starts well before the visible “open,” and at Swaps Monitor, we provide the granularity you need to take advantage of the complete trading window.

Why Projections Matter

At Swaps Monitor, our philosophy is simple: get it right the first time.

Every time a holiday changes, it costs our customers time and sometimes money. Settlement dates need to be reset, trade confirmations adjusted, valuations changed, and option expiry dates modified. We are very aware of these costs and invest heavily in getting it right in the first place.

A Case in Point

📅 Mumbai 2026 Holidays

India’s holidays are very complex – blending lunar and solar calendars with political decisions about which festivals to favor. Dates shift every year.

The official government holidays for 2026 in Mumbai were not announced until December, 2025. Yet we had already projected them correctly—no update required.

Coming Up on December 19: Triple Witching Day — A Potential Market Disruptor

Four times a year, US markets face Triple Witching – the simultaneous expiration of stock options, index options, and index futures

Traders must close, roll, or rebalance positions—often resulting in sudden bursts of buying and selling, rapid exposure shifts, and heightened volatility, often in the final trading hour

When markets operate under this kind of pressure, having accurate dates and times is essential for effective planning and risk management. 

At Swaps Monitor, we provide: 
✔️ Triple Witching dates 
✔️ Trading hours for all the relevant contracts 
✔️ Expiry dates and times 

Make informed decisions before the volatility arrives.

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.
