Max pain
The strike at which the open options of one expiry would pay their holders the least at settlement.
Max pain is computed per expiry from open interest: for each candidate strike, add up what every open call and put of that expiry would be worth if it settled there, and take the strike where that total is lowest. It is where option holders as a group would lose the most and option writers would keep the most. How to read it: max pain is a reading of where open interest sits, not a forecast; nothing requires the price to settle there, and a large move before expiry changes the open interest it is computed from. The options page gives it per expiry, and the front expiry's value is recorded daily.
