How to read this
Dealers who sell options hedge their risk by trading the underlying stock. Gamma exposure (GEX) estimates how much dealer hedging pressure sits at each strike. The call wall is the strike with the largest positive dealer gamma: rallies tend to slow there as dealers sell into strength. The put wall is the strike with the largest negative gamma: selloffs tend to accelerate there as dealers sell into weakness. The zero gamma flip is the level where total exposure changes sign: above it, hedging dampens moves (pinning); below it, hedging amplifies moves. When no flip exists inside the tracked strikes, positioning is one-signed across the whole chain. This is a model with a standard assumption (dealers short calls, long puts), not an observable fact.
