Nifty Option Chain Live

How to read this option chain

The table above shows every actively traded Nifty strike for the selected expiry: Calls on the left, Puts on the right. Four columns decide most trades — open interest (OI), change in OI, implied volatility (IV) and last traded price (LTP).

The strike with the highest Call OI is where option writers are selling most aggressively — the market's working resistance. The highest Put OI marks the same on the downside — working support. Together they define the range option sellers are defending; the summary above the table computes both live, along with the put-call ratio and max pain for the expiry.

What to check before a trade

Spot alone tells you direction; the chain tells you positioning. Before entering, check three things in the table. First, where today's fresh OI is building — a strike adding OI intraday matters more than one carrying stale positions (the change in OI view isolates this). Second, IV at your strike versus neighbouring strikes: buying options at inflated IV means the trade must overcome both direction and volatility decay. Third, LTP against intrinsic value at ATM strikes — wide time premiums near expiry indicate the market expects movement.

Expiry matters more than most beginners think

Nifty currently trades weekly and monthly expiries [VERIFY current expiry day — shifted in Sept 2025]. Positioning resets at each expiry: OI concentrations that acted as support last week may be irrelevant this week. Always confirm which expiry the table is showing (selector above) — comparing strikes across different expiries is the most common reading error.

FAQs

How often does this option chain update?

Data refreshes every minute during NSE market hours (9:15 AM–3:30 PM IST). The timestamp above the table shows the last update. Outside market hours the chain shows closing values, labelled "at close."

What does high OI at a strike mean?

Large open interest means many contracts are outstanding there — usually written by sellers. High Call OI acts as resistance, high Put OI as support, because writers defend those levels until expiry approaches.

Which expiry should I look at?

The nearest expiry for intraday and weekly trades — it carries the most volume and the most current positioning. Use monthly expiries for positional trades; their OI shifts more slowly.

Why did the OI at a strike suddenly drop?

Either positions were squared off (unwinding) or the data rolled to a new expiry. Check the expiry selector first, then the change-in-OI view to see whether it was genuine unwinding.

Is this data delayed?

No login is required and the data is sourced from NSE with refresh through market hours. Tick-by-tick streaming is not necessary for OI analysis — OI itself updates on the exchange in intervals.

Can I see Greeks here?

Yes — switch the table to Greeks mode to view delta, theta, gamma and vega per strike, computed from live IV.

What's the difference between this page and the change-in-OI page?

This page shows total positioning per strike. The change in OI page shows what's being added or removed today — better for reading intraday shifts.
