How to read block deal data
Block deals are the cleanest large-trade disclosure the exchange publishes: one buyer, one seller, one price, agreed in advance and executed in a window designed so a large position can change hands without dragging the open-market price with it. Both sides are named.
That symmetry is the thing most commentary gets wrong. Every block deal has a seller as large as the buyer, so the existence of a block deal is not directional information — somebody was convinced enough to buy and somebody was convinced enough to sell, at a price they both accepted. What is genuinely useful is who: a named institution taking a large stake in a small company changes the shareholder register in a way that shows up in the next quarterly filing, and the negotiated price is a real mark from a real buyer.
Block deals are sparse — often only a handful a session, sometimes none — which is why this page carries several weeks of tape instead of one day. For a fuller picture of large trades see bulk deals, and for what the company's own promoters and directors are doing, insider trading.
Common questions
What is a block deal?
A block deal is a single large trade negotiated between two parties and executed in a dedicated block-deal window, separate from the normal order book. SEBI sets a minimum size for the window (currently ₹10 crore), and the price must sit inside a narrow band around the reference price. Because both legs are pre-agreed, a block deal moves a large position without walking it through the open market.
How is a block deal different from a bulk deal?
A block deal is negotiated off-book and executed in a special window at a pre-agreed price. A bulk deal is an ordinary market trade — or a set of them — that happens to cross 0.5% of a company's listed shares over the session. Block deals are typically a single counterparty exiting or entering in one shot; bulk deals often reflect accumulation across the day.
Why are there so few block deals compared to bulk deals?
The block window is narrow — a short slot at the start of the session — and the minimum trade size is large, so only a handful qualify on most days. Some sessions have none at all. That is normal, and it is why this page shows several sessions of history rather than one day in isolation.
Are block deals a buy signal?
No. A block deal has a buyer and a seller of equal size, which by itself tells you nothing about direction — one institution's conviction is another's exit. It is information about who now owns a large stake, at what price, and that is worth knowing; it is not a recommendation.
How current is this block deal data?
Pulled from the exchange after each session closes and rebuilt with the rest of the site. The page states which session it is showing and flags it if the exchange feed has stopped moving.
