## Max pain and dealer gamma by expiry

Nearest expiries first. Max pain is the strike where open interest would expire worth the least; the expected move is one standard deviation from at-the-money implied volatility; net GEX is the dealers' estimated gamma exposure for that expiry, positive damps moves and negative amplifies them.
