Block Deals Today – Track Large Institutional Stock Trades

These trades are typically executed by:
- Institutional investors

- Foreign investors (FIIs)
- Promoters
- High Net Worth Individuals (HNIs)
Because these types of deals involve large volumes and significant capital, traders closely monitor them to identify major investor activity in the market.
Below, you can explore the latest deals data from NSE and BSE using the interactive tracker.
This widget displays recent block deals executed in the stock market, including transaction value, investor name, quantity, and price.
What is a Block Deal in the Share Market?
A block deal is a large transaction of shares executed through a separate block deal window provided by stock exchanges.
To qualify as a block deal, the trade must meet one of the following criteria:
• Minimum 5 lakh shares, OR
• Minimum ₹10 crore transaction value
These deals are usually pre-negotiated between two parties before execution to reduce market impact.
Block Deal Window Timings
Block deals can only be executed during specific time windows on stock exchanges.
Morning Window
8:45 AM – 9:00 AM
Afternoon Window
2:05 PM – 2:20 PM
These windows allow large investors to execute big trades without disrupting the regular order book.
Orders that do not match during the window are automatically cancelled.
