TTAN's closing options book on October 20, 2026 carried +$383K of net dealer gamma spread across 5 expirations and 11 contracts. The sign is positive, so hedging leans against the move rather than with it.
TTAN's apex — the strike carrying the most gamma in absolute terms — is 75, the same strike as its call 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 call wall has printed two different strikes. Walls that stay put and walls that migrate every session are different objects.
What TTAN's walls are — and aren't
TTAN's book has been recorded on 81 sessions. Its average daily range over that stretch was 5.55% 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.
