Max Pain

Max Pain (or Maximum Pain) is a theory in options trading that suggests the price of an underlying asset will gravitate toward the strike price where the maximum number of options (calls and puts) will expire worthless.

The Theory of Market Maker Hedging

Market makers are the primary sellers (writers) of options contracts. To remain market-neutral, they hedge their positions in the spot or futures markets. As options approach expiry, the "gamma" of these positions increases, requiring market makers to buy or sell more of the underlying asset to stay hedged. This mechanical buying and selling often exerts a "gravitational" pull on the price, drawing it toward the level that minimizes the total payout market makers must make to options buyers.

How It Is Calculated

Max Pain is calculated by summing the dollar value of all outstanding open interest for both calls and puts across every strike price for a specific expiry date. The strike price with the lowest aggregate dollar value is the Max Pain point.

Usage as an Indicator

Traders watch Max Pain levels—especially for major monthly expiries—as potential support or resistance zones. If the current spot price is significantly far from the Max Pain price as expiry approaches, there is a statistical probability of a "reversion to the mean" as market maker hedging flows intensify.
