What Is Max Pain in Options?
The max pain strike, how it is calculated from open interest, why some traders watch it near expiry, and why it is not a price target.
Updated 4 Oct 2026
Max pain is the expiry price at which option buyers, in total, would lose the most - equivalently, where the total value of all open calls and puts at expiry would be smallest.
How it is calculated
For each possible expiry price (each strike), add up what every open call and put would be worth at expiry using the current open interest. The strike with the smallest total payout is the max pain strike.
Why traders watch it
The theory is that because option writers hold large hedged positions, the index sometimes drifts toward the max pain level as expiry approaches. Some traders use it as a reference level on expiry day.
Why it isn't a target
Max pain moves as open interest changes and has no influence on the market in trending conditions. Treat it as one input among many, never as a prediction.
Hindi mein saar
Max pain wo strike hai jahan expiry pe saare open calls aur puts ki kul value sabse kam hoti hai, yaani option buyers ko sabse zyada nuksaan. Kuch traders maante hain ki expiry ke kareeb index iske paas aata hai, lekin ye target nahi - sirf ek reference level hai.
