The put wall is the mirror of the call wall: in positive gamma, dealer hedging cushions dips into it, so declines tend to stall and bounce there. A dip that holds the put wall is a textbook long — buy calls for the move back toward the middle.
The setup
Price dips toward the put wall in a positive-gamma regime. You're waiting to see the level defended — sellers running out of steam as the mechanical bid absorbs the dip. This is buying weakness into known support, not catching a falling knife in a vacuum.
Entry, target, stop
Entry: the hold — a bounce or reversal candle at the wall, the dip refusing to continue. Target: back toward VWAP or gravity. Stop: a decisive, held break below the wall — that's invalidation, because a broken put wall can feed a negative-gamma slide, and you never want to be long into that.
Buy the hold, not the touch. The floor is a trade when it's defended — a warning when it breaks.
When to skip
Skip it in negative gamma, where the floor is fragile and a break accelerates down. Skip it if price is slicing toward the wall on rising velocity rather than dipping into it — that's momentum that may not respect support. The put wall is a high-quality bounce zone only while the regime is calm. NoVo maps the wall and the regime so you buy the bounce the positioning is actually defending.
