Indicative Price (Closing Auction)

The indicative price pages chart the index value the exchange publishes during the Closing Auction Session (CAS), one print per second, beside the live ATM straddle. From 3:15 PM the normal index stops updating, so the indicative value is the only live index level until the official close prints.

What it is

Since 3 August 2026, NSE and BSE end the cash session with a Closing Auction Session (CAS). Stocks with F&O contracts leave continuous trading at 3:15 PM and move into a call auction. During the auction the exchange publishes an indicative price for each stock, the price the auction would clear at if it ended now, and an indicative index built from those prices.

The continuous index freezes at its 3:15 PM value. Index options keep trading until 3:40 PM. On expiry day, the settlement price of an expiring index contract comes from the auction close. So the straddle is priced against a frozen spot while the indicative is still moving.

The indicative is not the closing price. It moves with every order added or pulled. Order entry closes at a random moment between about 3:28 and 3:30 PM, and the official close is struck once from the matched result. On the chart, the line goes flat at that close.

What you see

• Two panes. The left pane is the full straddle chart: straddle premium, spot, synthetic future, VWAP and EMAs, with the ATM ± 5 option chain beside it. The right pane is the indicative index for the session.
• Indicative tile. The spot card shows Indicative under the index, with a CAS tag from 3:15 PM. Spot and futures tiles are dimmed while the index is frozen.
• Outside the window. The pane holds the most recent recorded auction, dated on its legend chip, and switches to today's prints when the first one arrives.
• Key facts for the index's auction, and Recent closing auctions: a table of First print, Low, High, Close (settled at) and Range for each session, with the time of each print in IST.
• Downloadable copies of the recent-auction data in Markdown and JSON, for example /nifty-indicative-price.md and /nifty-indicative-price.json.

How to use it

1. Sign in with your broker and open Nifty indicative price, or open it directly; it opens without signing in.
2. Keep the two-chart layout on so the indicative pane is visible.
3. From the first print, read the indicative against the frozen 3:15 PM spot and the straddle premium on the left.
4. Use Compare session to pick a past date. The left pane draws that day's straddle and the right pane draws that day's auction.

FAQ

Where can I track the Nifty indicative price live?

At quintalmind.com/nifty-indicative-price. It charts the NSE indicative Nifty at one print per second during the closing auction, beside the live ATM straddle. Bank Nifty and Sensex have their own pages.

What is the indicative price?

It is the index value computed from the indicative auction prices of its stocks during the Closing Auction Session: the level the index would close at if the auction ended now. It is not the closing price until the auction settles.

Why does Nifty spot stop moving at 3:15 PM?

Since 3 August 2026, stocks with F&O contracts leave continuous trading at 3:15 PM for a closing auction, and the exchange stops publishing the continuous index. Index options keep trading until 3:40 PM.

Can I see yesterday's closing auction?

Yes. Outside the auction window the pane holds the most recent recorded session, and the compare calendar draws any past session's auction beside that day's straddle.
