These are the October 20, 2026 closing levels. Members see BMNU's board live all session, with the odds of reaching each level.
BMNU's closing options book on October 20, 2026 carried −$10K of net dealer gamma spread across 5 expirations and 12 contracts. The sign is negative, so hedging runs with the move rather than against it.
BMNU's apex — the strike carrying the most gamma in absolute terms — is 16, 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 5 different strikes. Walls that stay put and walls that migrate every session are different objects.
What BMNU's walls are — and aren't
BMNU's book has been recorded on 52 sessions. Its average daily range over that stretch was 11.61% 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.

The heaviest put-side strike is 16, 6.7% above the October 20, 2026 close.
BMNU does not have a well-defined gamma flip in the current book.
Not reliably. Walls mark where dealer hedging is heaviest — positive gamma absorbs moves, negative gamma amplifies them — but levels are not bounce points, and across our grading walls contained price no better than a same-width band around the prior close (BMNU's book has been recorded on 52 sessions).
