BX closing levels — September 4, 2026. Drawn to scale.

BX's closing options book on September 4, 2026 carried −$8.3 million of net dealer gamma spread across 5 expirations and 251 contracts. The sign is negative, so hedging runs with the move rather than against it.

The heaviest call-side strike sits at 150 and the heaviest put-side strike at 140, a band 7.3% wide. BX has averaged 3.12% between its high and its low over the last 89 sessions, which makes the full width of that band about 2.4 average sessions of travel. It closed below the put wall entirely.

BX closed at 136.15 — 10% below the call wall and 2.8% below the put wall. The put side is the nearer of the two at 2.8% 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.

BX's apex — the strike carrying the most gamma in absolute terms — is 140, 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 call wall has printed two different strikes, and its put wall has printed two different strikes. Walls that stay put and walls that migrate every session are different objects, and the difference shows up here before it shows up in price.

How BX has behaved around these levels

Over the last 89 recorded sessions, BX closed between the previous session's put wall and call wall 65 times. Its average daily range over that stretch was 3.12% of price. These are descriptions of what already happened — they are not a forecast, and no level holds every time.
