MSTR gamma levels
From the closing options book · October 19, 2026
MSTR closed at 136.02 on October 19, 2026. Its call wall was 148, put wall 125, the Apex (the strike with the most dealer gamma) 148, and the gamma flip 146.5. Net dealer gamma was positive, so hedging tends to absorb moves. Net dealer gamma is positive, but price closed below the flip, so the cushion is thin: a push lower can tip it negative.
These are the October 19, 2026 closing levels. Members see MSTR's board live all session, with the odds of reaching each level.
MSTR's closing options book on October 19, 2026 carried +$23.3 million of net dealer gamma spread across 5 expirations and 290 contracts. The sign is positive, so hedging leans against the move rather than with it.
The heaviest call-side strike sits at 148 and the heaviest put-side strike at 125, a band 17% wide. MSTR has averaged 5.65% between its high and its low over the last 89 sessions, which makes the full width of that band about 3.0 average sessions of travel. It closed close to the middle of that band.
MSTR closed at 136.02 — 8.8% below the call wall and 8.1% above the put wall. The put side is the nearer of the two at 8.1% away, which is the only reason it is worth watching more closely than the other. Most levels drawn on a chart are never reached at all, and the distance is what separates them.
The gamma flip is at 146.5, 7.7% above the close. It is the price where the summed book changes sign — an estimate read from the chain, shown as a price rather than a line price respects.
MSTR's apex — the strike carrying the most gamma in absolute terms — is 148, 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 5 different strikes, and its put wall has printed 4 different strikes. Walls that stay put and walls that migrate every session are different objects.
What MSTR's walls are — and aren't
MSTR's book has been recorded on 89 sessions. Its average daily range over that stretch was 5.65% 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.

MSTR's heaviest call-side gamma strike is 148, measured from the closing options book on October 19, 2026. That is 8.8% above where it closed, against an average daily range of 5.65%.
The heaviest put-side strike is 125, 8.1% below the October 19, 2026 close. Together with the 148 call wall it brackets a band 17% wide.
MSTR's gamma flip is at 146.5, 7.7% above the close. Above it the book is net positive gamma; below it, net negative.
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 (MSTR's book has been recorded on 89 sessions).
