BSE Bankex Option Chain, Max Pain & OI
Live BSE Bankex option chain, max pain, open interest and PCR for the BSE banking index.
BSE Bankex is the banking-sector index on the Bombay Stock Exchange — the BSE counterpart to BankNifty — and carries the same high-beta character that makes banking-index options fast-moving and premium-rich. It trades with a 100-point strike gap.
This page covers reading the Bankex option chain, max pain, open interest and PCR — all streamed live and lot-adjusted on Quintal Mind.
Reading the Bankex Option Chain
The Bankex 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. Bankex options trade with a strike gap of 100 and a lot size of 30.
Quintal Mind streams the Bankex 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.
Bankex Max Pain & Open Interest
Max pain — the strike where the most Bankex 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 Bankex 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.
Bankex PCR & Sentiment
The Bankex 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.
