S3 · Stacked floor at the put wall

A directional drop stops dead because four independent elements are stacked on the same zone: the 0DTE put wall, a positive GEX (MM) bar just below it, an options flow that adds positive gamma, and large aggressive buyers on ES. None of the four is enough on its own. When they are all there, the floor is real, even in a short gamma regime, and it is the most profitable trade of the two sessions studied in this course.

The idea

The put wall is the strike where the most puts are concentrated below price. It has two faces: support, if hedging buys the dip; breaking point, if market makers are short puts and accelerate. What removes the doubt is the stacking: a positive GEX (MM) bar just below the wall (a cushion), a large print of puts sold or calls bought (dealers buy ES to hedge and become long gamma around the strike), and buying Deep Trades bubbles on the zone.
