A range day — a calm, positive-gamma session where dealer hedging mean-reverts price — produces a rotation: price oscillates between the day's bookends, pivoting around VWAP. The playbook is to trade that rotation, fading both edges instead of picking a direction.

The rotation

Define the range: the upper edge (call wall / expected-move high / range high) and the lower edge (put wall / expected-move low / range low), with VWAP and gravity as the middle. Then sell the upper edge (buy puts on a rejection) targeting the middle, and buy the lower edge (buy calls on a hold) targeting the middle. VWAP is the pivot — take profit into it, and use its reclaim/loss to gauge which half of the range price favors.

Entries and exits

Fade the reactions at the edges (a call-wall rejection, a put-wall bounce), not the levels themselves, and target the middle or the opposite edge. Scale out into VWAP/gravity. Keep each leg tight — range-day moves are small, so overstaying gives profits back to chop and theta.

A range day pays you twice — once fading the top, once buying the bottom. The pivot is VWAP; the trap is forgetting range days end.

When the rotation ends

The rotation works because the regime is calm, and range days become trend days. The instant an edge breaks and holds (price accepts a move beyond the range), or the trend-day checklist lights up, the rotation is over — stop fading and respect the break. Fading the edge that finally breaks is how a profitable range day turns red at the close. NoVo maps the edges and the regime so you know when the range is intact and when it's giving way.
