From the closing options book · October 19, 2026
EFA closed at 102.87 on October 19, 2026. Its call wall was 112, put wall 103, the Apex (the strike with the most dealer gamma) 103. Net dealer gamma was negative, so hedging tends to amplify moves.
These are the October 19, 2026 closing levels. Members see EFA's board live all session, with the odds of reaching each level.
EFA's closing options book on October 19, 2026 carried −$125.0 million of net dealer gamma spread across 5 expirations and 237 contracts. The sign is negative, so hedging runs with the move rather than against it.
The heaviest call-side strike sits at 112 and the heaviest put-side strike at 103, a band 8.7% wide. EFA has averaged 0.75% between its high and its low over the last 89 sessions, which makes the full width of that band about 11.7 average sessions of travel. It closed sitting on the put wall.
EFA closed at 102.87 — 8.9% below the call wall and level with the put wall. The put wall is not a distance away at all; price finished on it, which is the one state where a level is unambiguously in play. Most levels drawn on a chart are never reached at all, and the distance is what separates them.
EFA's apex — the strike carrying the most gamma in absolute terms — is 103, 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 5 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 EFA's walls are — and aren't
EFA's book has been recorded on 89 sessions. Its average daily range over that stretch was 0.75% 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.

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 (EFA's book has been recorded on 89 sessions).
