Pre-open order book
NSE runs a call auction from 09:00 to 09:15 before normal trading starts. This is the order book from that auction: the biggest resting orders, which way each book is leaning, and the gap those orders imply against the previous close.
Today's pre-open auction opens at 09:00 IST. Showing the last session we hold, from Thu 13 Aug 2026, stamped 09:07:34 IST.
Big resting orders
Level value = quantity resting at that price level x that price, in rupees. Each stock contributes its single largest level.

|---|---|---|---|---|---|
| HDFCBANK | Sell | 726.95 | 1,00,000 | 7.27 Cr | -0.29% |

These are the orders that did NOT match. NSE publishes the top 5 unmatched price levels a side of the residual book, so every ladder is truncated.

How to read this
These orders have not traded. The pre-open call auction takes orders from 09:00 to 09:08, and any of them can be modified or cancelled right up to that cut-off. A large resting quantity is an intention, not a purchase, and nobody knows who placed it.
Derivatives have no pre-open session. Futures and options open at 09:15. The F&O view is the pre-open book of the 208 underlying stocks, which is the closest honest read available before the derivative starts trading.
Book imbalance = (totalBuyQuantity - totalSellQuantity) / (totalBuyQuantity + totalSellQuantity), over the whole residual book.
Implied gap = (IEP - previousClose) / previousClose. Computed here, not read from NSE pChange, which disagrees with its own price fields on some rows.
Eligible = a two-sided book worth at least Rs 1 crore. One-sided books are listed separately, never mixed in.

What happened next, measured
Of the names this board highlighted each morning, how many closed above their own opening price that day. This is a record of what happened, not a prediction, and not advice.
