As ofCboe delayed snapshot Nov 10, 6:11 AM ET
HowOver every strike with open interest for the 2026-11-13 expiration: (call gamma × call OI minus put gamma × put OI) × 100 × spot² × 1%, summed. Calls count as positive and puts as negative, a convention about who holds the other side, not a measurement.
■ put-side pain■ call-side painTotal payout option writers would owe at each settle price (both sides, all open interest, ×100 shares) — low settles hurt put writers, high settles hurt call writers. The minimum — 11.5 — is the max pain price.

Stacked — layer the expirations
Call open interest per strike, stacked across the checked expirations — each color is one expiry. Strikes are pruned to the liquid center of each chain.
Max pain is arithmetic, not prophecy: the settle price that would minimize what option writers pay out at expiration, computed from open interest alone. Prices sometimes gravitate toward heavy strikes into expiry — dealer hedging is a real flow — but the evidence that max pain predicts settlement better than chance is mixed, and we are not going to pretend otherwise. Use it as a map of where positioning is stacked, next to the fundamentals and the earnings calendar, not as a target.
Max pain, walls and gamma print only when an expiration holds at least 100 open contracts across 5 strikes, and max pain also needs to stay within 5% of spot when its single heaviest strike is removed. Below that the expiration reads as thin rather than printing a level one trade could move.
Data: Cboe delayed public feed (~15 minutes), refreshed here about every 15 minutes. Open interest itself updates once daily, before the open. Educational information, not investment advice.
