Max pain is the strike at which option holders lose the most at expiration. Gamma exposure (GEX) estimates how much options dealers must hedge as the stock moves: positive gamma tends to dampen moves, negative gamma amplifies them, and the gamma flip is the price where net GEX changes sign. Call and put walls are the strikes where call and put gamma exposure is most concentrated, often read as resistance and support. Methodology
