Option ChainNifty Option Chain Analyzer — Live

An option chain is a table showing all available call (CE) and put (PE) strike prices for an underlying like Nifty 50 or Bank Nifty, with key data per strike — last traded price (LTP), open interest (OI), volume, implied volatility (IV) and bid/ask. It is the primary tool F&O traders use to read where institutional money is positioned and where strikes are likely to act as support or resistance.

PCR is total Put OI divided by total Call OI for the selected expiry. Above 1.2 indicates put-heavy positioning (often bullish — puts are being written as support). Below 0.7 indicates call-heavy positioning (often bearish — calls are being written as resistance). Extremes above 1.5 or below 0.5 can signal contrarian reversals.

Max pain is the strike price at which the total dollar value of outstanding options (both calls and puts) is at a minimum — i.e. where option writers would lose the least on expiry. Spot prices tend to gravitate toward max pain as expiry approaches, especially in the final hour of expiry day.

A gamma zone is a strike range with extreme gamma exposure, usually near ATM and close to expiry. Small spot moves through these strikes cause amplified delta hedging by market makers, which can trigger rapid 5-20x premium spikes. Our analyzer flags gamma zones automatically.
