What is Options Max Pain?
Max pain (also called "options pain" or "max option pain") is the strike price at which the total dollar value of all outstanding options contracts would lose the most if the stock expired at that price. It represents the price point where option writers (sellers) would pay out the least, and option holders would experience maximum collective loss.
The max pain theory suggests that stocks tend to gravitate toward the max pain price as expiration approaches. This is because market makers and institutional option sellers hedge their positions in ways that can push the stock toward the price where the most options expire worthless. While not a guaranteed predictor, many traders use max pain as one reference point in their expiration-week analysis.

Max Pain Strike
The strike price where the total dollar value of all in-the-money options is minimized. At this price, the most options expire worthless.
Call Pain
The total dollar loss for all call option holders if the stock expired at a given price. Higher when the stock is above the strike.
Put Pain
The total dollar loss for all put option holders if the stock expired at a given price. Higher when the stock is below the strike.
