Calculating Bitcoin Options Max Pain Before Expiration

Summary

This educational article defines max pain as the expiration price at which the aggregate intrinsic value owed to option buyers across an expiry is lowest. To calculate it, assess the intrinsic value of every open call and put at each available strike as though settlement occurred there, sum the values for each candidate price, and select the strike with the smallest total. Open interest supplies the position data; it differs from volume because it counts contracts that remain open.

The article says max pain is most relevant close to expiration when an expiry has substantial open interest, since large positions may create incentives to influence prices. It also notes that Deribit settlement uses a 30-minute time-weighted average of its index, rather than a single final trade. Max pain is presented as a limited contextual indicator, not a reliable standalone forecast: high open interest or a calculated strike does not prove that traders will move prices toward it, and the calculation ignores individual positions.

Key ideas

• Max pain is the candidate expiration price that minimizes total intrinsic value payable to option buyers.
• The calculation evaluates all open calls and puts at each available strike and compares their summed intrinsic values.
• Open interest counts positions still open, while volume also includes trades that have since closed.
• The article considers max pain more relevant when time to expiry is short and open interest is high.
• Settlement methodology and other market information matter, so max pain alone is a limited signal.
