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.
Reading the Sensex Option Chain
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 — the strike where the most Sensex 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 Sensex 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.
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.
