The NIFTY and BANKNIFTY option chain, built to be read
Every strike for an expiry on one screen: premium, open interest, implied volatility and Greeks, live during market hours.
What the chain shows
The full NSE option chain for every index we cover, strike by strike: calls on the left, puts on the right, the at-the-money row marked and in-the-money strikes shaded. Each strike carries its last traded price through the session, implied volatility per contract, open interest and the change in open interest, so the day's positioning and the day's prices sit in one view instead of two tabs.
Open interest you can see
Open interest is drawn as depth bars rather than printed as a number. The question you are actually asking is where the weight sits, which strikes the market is defending, and a column of six-digit figures is the one presentation that hides it. With bars, support and resistance built from positioning is visible at a glance, which is most of what people mean by option chain analysis.
Max Pain, PCR and the ATM strike, computed for you
Max Pain, the put-call ratio and the at-the-money strike are computed across the whole chain as it updates, so the three numbers most often worked out by hand are simply there. The Greeks guide explains what Delta, Theta and Vega mean per strike; the chain is where you watch them move.
From reading the chain to acting on it
Strikes are picked straight from the chain into the strategy builder, where the position's payoff, breakevens and estimated margin assemble themselves. If you are new to all of this, start with the options basics guide and come back: the chain makes much more sense once premium and moneyness do. To watch a chain through a real past day, Session Analysis replays one minute by minute.
Option chain questions
What is an option chain?
An option chain lists every strike for one underlying and expiry, with calls on one side and puts on the other. Each row shows the premium, open interest and implied volatility for that strike, so you can see prices and positioning for the whole expiry at once.
How do I read open interest on an option chain?
Open interest is the number of contracts still open at a strike. Large put OI below the market and large call OI above it are often read as support and resistance. EzyOptions draws OI as depth bars per strike, so the heavy strikes stand out without reading numbers.
Is the EzyOptions option chain live?
Yes, during NSE market hours, 9:15 to 15:30 IST on trading days, prices, open interest and Greeks update live from the data feed, and the app labels data as closed outside those hours. Greeks arrive with the chain from the data vendor; a strike that has not traded shows a dash for theta, gamma and vega.
