In a positive-gamma regime, dealer hedging leans against advances into the call wall — so price tends to grind up, stall, and reject rather than blow through. That rejection is the setup: buy puts for the fade back toward the middle.

The setup

You want price grinding up toward the call wall in positive gamma (check the regime first — this is a positive-gamma trade). The closer to the wall and the more tired the grind, the better. You're fading strength into known mechanical resistance, not shorting into a vacuum.

Entry, target, stop

Entry: the rejection — a stall or reversal candle at the wall, buyers failing to push through. Target: back toward gravity or VWAP, the natural mean-reversion objectives. Stop: a decisive, held break above the wall — that's your invalidation, because a wall that breaks can accelerate, and you do not want to be short into that.

Fade the failed test, not the level itself. The trade is confirmed when the wall rejects — not when price merely reaches it.

When to skip

Skip it in negative gamma, where the wall is a launchpad, not a ceiling — fading there fights an amplifying tape. Skip it when the wall is migrating up (the ceiling is stepping back, confirming demand). And respect that even a good fade needs the regime on its side. NoVo maps the wall and the regime together, so you're only fading a test the positioning actually supports.
