The flip

The level where dealer hedging turns from steadying price to amplifying it. A key read on the session's structure.

The walls

Strikes where positioning concentrates and price tends to pin or stall — the day's magnets and barriers.

The regime

Whether today's structure dampens volatility or feeds it — the backdrop every level sits inside.

Not a theory. Dealer hedging can measurably affect price behavior — documented in peer-reviewed research on option-expiration pinning and gamma fragility.
