PCG gamma levels
From the closing options book · October 20, 2026
PCG closed at 13.18 on October 20, 2026. Its call wall was 14, put wall 11, the Apex (the strike with the most dealer gamma) 14, and the gamma flip 13.75. 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 20, 2026 closing levels. Members see PCG's board live all session, with the odds of reaching each level.
PCG's closing options book on October 20, 2026 carried +$673K of net dealer gamma spread across 5 expirations and 90 contracts. The sign is positive, so hedging leans against the move rather than with it.
The heaviest call-side strike sits at 14 and the heaviest put-side strike at 11, a band 23% wide. PCG has averaged 3.55% between its high and its low over the last 87 sessions, which makes the full width of that band about 6.4 average sessions of travel. It closed in the upper third of that band.
PCG closed at 13.18 — 6.2% below the call wall and 17% above the put wall. The call side is the nearer of the two at 6.2% 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 13.75, 4.3% 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.
PCG's apex — the strike carrying the most gamma in absolute terms — is 14, 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 two different strikes. Walls that stay put and walls that migrate every session are different objects.
What PCG's walls are — and aren't
PCG's book has been recorded on 87 sessions. Its average daily range over that stretch was 3.55% 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.

Common questions
PCG's heaviest call-side gamma strike is 14, measured from the closing options book on October 20, 2026. That is 6.2% above where it closed, against an average daily range of 3.55%.
The heaviest put-side strike is 11, 17% below the October 20, 2026 close. Together with the 14 call wall it brackets a band 23% wide.
PCG's gamma flip is at 13.75, 4.3% 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 (PCG's book has been recorded on 87 sessions).
