BSE Bankex Max Pain Analysis

BSE Bankex's max pain is the strike where option writers face minimum total loss at expiry. Updated daily after option chain data is refreshed.

BSE Bankex's max pain is calculated by taking every possible expiry price and computing the total ITM payout to all option buyers: sum of (CE OI × max(0, spot − strike)) + (PE OI × max(0, strike − spot)) for all strikes. The strike with the minimum total payout is the max pain — where option writers collectively lose the least.

Max pain theory suggests the underlying tends to gravitate toward the max pain strike as expiry approaches, because option writers (who have the capital and hedging ability) can influence spot price. It's more reliable within 1 week of expiry and for liquid stocks like BSE Bankex. It should be used with other signals, not in isolation.

BSE Bankex's max pain shift from the previous session is tracked daily. Consistent upward shifts are bullish; downward shifts are bearish signals.

BSE Bankex options follow the NSE monthly expiry schedule — last Tuesday of each calendar month. MarketNetra tracks max pain for the nearest expiry.
