Nifty Bank Option Chain, Max Pain & OI
Live BankNifty option chain, max pain, OI and PCR — for India's most volatile index.
BankNifty (Nifty Bank) is the high-beta cousin of Nifty — fewer constituents, heavier weightings and sharper intraday swings, which make its options richer and faster-moving. Its 100-point strike gap and concentrated banking exposure attract directional and volatility traders alike.
This page covers reading the BankNifty option chain, max pain, open interest and PCR, all streamed live on Quintal Mind.

The BankNifty 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. BankNifty options trade with a strike gap of 100 and a lot size of 30.
Quintal Mind streams the BankNifty 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.
BankNifty Max Pain & Open Interest
Max pain is the candidate settlement price that minimises the combined intrinsic payout of outstanding BankNifty calls and puts for one expiry, weighted by open interest. It can change as OI changes and does not predict where the underlying will settle. Call and put OI concentrations show positioning, not guaranteed resistance or support.
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.
BankNifty PCR & Sentiment
The BankNifty 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.
Frequently Asked Questions
What is the BankNifty lot size and strike gap?
BankNifty options have a lot size of 35 and a strike gap of 100 points.
Why is BankNifty more volatile than Nifty?
BankNifty has fewer constituents with larger individual weightings, all from the banking sector, so it moves more sharply than the broader, more diversified Nifty 50 — which is reflected in higher option premiums.
