NDX Gamma Exposure Today: Positioning Walls and the Flip

Every number here is computed from the traded NDX options chain. The call wall is where dealer hedging accumulates above spot and caps upside, the put wall is its mirror below, and the gamma flip is the level where hedging stops damping moves and starts amplifying them.
