Open-interest change — building vs unwinding

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
History starts accruing now: first snapshot taken 2026-07-28. We chart only days we actually observed — check back as the record builds. The measured hit-rate across all tickers lives on the accuracy ledger.
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.
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.
