How Max Pain of Sensex Is Calculated
Sensex max pain calculation includes the following steps:
Get open interest figures for every call and put strike in the Sensex options for the given expiry date.
For every strike, calculate the in‑the‑money dollar value:
- For calls:
(Spot price – Strike price) × Open Interest - For puts:
(Strike price - Spot price) * Open Interest
Sum these values up for puts and calls over every strike.
Find the strike of the lowest total payout—that strike is the max pain level. This calculation shows where option writers will keep the most money and option buyers will have the biggest losses.
