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.
