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 history — nearest expiry vs price
— max pain (nearest expiry)- - delayed closeOne point per snapshot day since 2026-07-28; unobserved days are gaps, not guesses.
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.
