BEX closing levels — October 20, 2026. Drawn to scale.

BEX's closing options book on October 20, 2026 carried −$22K of net dealer gamma spread across 5 expirations and 16 contracts. The sign is negative, so hedging runs with the move rather than against it.

BEX's apex — the strike carrying the most gamma in absolute terms — is 22, the same strike as its put wall. When those stack on one level the book is concentrated rather than spread, and that single strike is doing most of the work.

Across the last 10 recorded sessions its put wall has printed 4 different strikes. Walls that stay put and walls that migrate every session are different objects.

What BEX's walls are — and aren't

BEX's book has been recorded on 73 sessions. Its average daily range over that stretch was 14.84% of price. Walls are where dealer hedging is heaviest — positive gamma absorbs moves, negative gamma amplifies them. They are not bounce points, and across our grading they contained price no better than a same-width band around the prior close.
