Nifty 50 Option Chain, Max Pain & OI
Live Nifty 50 option chain, max pain, open interest and PCR — built for weekly expiry traders.
Nifty 50 is the most actively traded options underlying in India, with weekly expiries that account for the bulk of NSE options volume. Its deep liquidity and 50-point strike gap make it the default playground for premium sellers and expiry-day traders.
This page covers how to read the Nifty option chain, max pain, open interest and PCR — all of which Quintal Mind streams live, lot-adjusted, with a heatmap to surface the strikes that matter.
Reading the Nifty Option Chain
The Nifty option chain lists every available call and put strike for the current expiry on NSE, with last price, volume, open interest, change in OI, implied volatility and bid–ask for each. Nifty options trade with a strike gap of 50 and a lot size of 75.
Quintal Mind streams the Nifty chain live over a compressed WebSocket, so LTP, OI and IV update in real time during market hours instead of the 3-minute delay on the exchange site. The ATM strike is highlighted and the chain is centred on spot so the relevant strikes are always in view.
Nifty Max Pain & Open Interest
Max pain — the strike where the most Nifty options expire worthless — is recalculated live as open interest shifts through the day. The highest call OI strike often acts as resistance and the highest put OI strike as support, and Nifty frequently gravitates toward the max pain level into expiry.
Watching OI change (not just absolute OI) tells you whether positions at a strike are being built or unwound — the difference between fresh conviction and a fading move.
Nifty PCR & Sentiment
The Nifty Put-Call Ratio (PCR), computed from total put OI ÷ total call OI, is a quick sentiment gauge: a high PCR leans bullish (heavy put writing), a low PCR leans bearish (heavy call writing). Quintal Mind shows live PCR alongside the chain so you have context before every trade.
Nifty Weekly Expiry
Nifty weekly options expire every Thursday (subject to NSE holiday shifts). The last two sessions before expiry see the most aggressive theta decay and the highest gamma risk — the environment where short straddles, iron butterflies and cross butterflies are most often deployed.
