What is
Max Pain?
Near expiry, price often seems to drift toward one strike. That strike is "max pain" — where option buyers hurt most and writers win most. Here's what it means, how it's calculated, and how to use it.
Max pain, defined
Max pain is the strike price at which option buyers as a group would lose the most money — and option writers (sellers) would keep the most — if the underlying settled there at expiry. It's also called the "point of maximum pain" for buyers.
The logic: most retail traders buy options and most professionals write them. If price expires at the level where the fewest options finish in-the-money, the maximum amount of premium paid by buyers evaporates worthless.
How max pain is calculated
It's a sum across the option chain:
- Pick a candidate expiry price (each available strike).
- For that price, calculate how much would be owed to every in-the-money call holder and put holder, weighted by each strike's open interest.
- Add it all up — that's the total payout to buyers at that price.
- Repeat for every strike. The strike with the lowest total payout to buyers is the max pain point.
In short: it's the strike where the combined in-the-money value of all calls and puts is minimised.
The "pinning" effect
As expiry approaches, option writers hedge their positions, and that hedging activity can nudge price toward max pain — a phenomenon traders call pinning. It's strongest in range-bound markets and on expiry day itself, when time value collapses fast.
How to use max pain (and how not to)
- Do treat it as a magnet / reference level near expiry, alongside OI support/resistance.
- Do watch whether price is converging toward or diverging from it.
- Don't trade it blindly — in strong trends or on news, price ignores max pain completely.
- Don't treat it as a precise target; it shifts intraday as OI changes.
