BSE Sensex Option Chain, Max Pain & OI
Live BSE Sensex option chain, max pain, open interest and PCR for the BSE benchmark index.
BSE Sensex is the 30-stock benchmark of the Bombay Stock Exchange and the most active options underlying on the BSE side, drawing strong volume on its weekly expiry. Its 100-point strike gap and large-cap composition make it a natural complement to Nifty for index traders.
This page covers reading the Sensex option chain, max pain, open interest and PCR — all streamed live and lot-adjusted on Quintal Mind.

The Sensex option chain lists every available call and put strike for the current expiry on BSE, with last price, volume, open interest, change in OI, implied volatility and bid–ask for each. Sensex options trade with a strike gap of 100 and a lot size of 20.
Quintal Mind streams the Sensex 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.
Sensex Max Pain & Open Interest
Max pain is the candidate settlement price that minimises the combined intrinsic payout of outstanding Sensex 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.
Sensex PCR & Sentiment
The Sensex 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.
