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

OVV's closing options book on October 20, 2026 carried +$863K of net dealer gamma spread across 5 expirations and 8 contracts. The sign is positive, so hedging leans against the move rather than with it.

The heaviest call-side strike sits at 75 and the heaviest put-side strike at 60, a band 21% wide. OVV has averaged 2.67% between its high and its low over the last 87 sessions, which makes the full width of that band about 8.0 average sessions of travel. It closed in the upper third of that band.

OVV closed at 70.29 — 6.7% below the call wall and 15% above the put wall. The call side is the nearer of the two at 6.7% 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.

OVV'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 3 different strikes, and its put wall has printed 3 different strikes. Walls that stay put and walls that migrate every session are different objects.

What OVV's walls are — and aren't

OVV's book has been recorded on 87 sessions. Its average daily range over that stretch was 2.67% 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.
