Open-interest change — building vs unwinding
Needs two observed snapshot days for this expiration — the comparison appears automatically once the next weekday snapshot lands. We diff real observations only; nothing is estimated.

Gamma exposure by strike · Fri, Mar 19
Net dealer gamma per strike, in dollars per 1% move, assuming the standard convention (dealers long calls, short puts) — an assumption, not an observation. Above the amber flip level hedging tends to dampen moves; below it, to amplify them.

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.
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.
