TEL gamma levels
From the closing options book · October 19, 2026
TEL closed at 212.33 on October 19, 2026. Its call wall was 240, put wall 200, the Apex (the strike with the most dealer gamma) 200. Net dealer gamma was negative, so hedging tends to amplify moves.
These are the October 19, 2026 closing levels. Members see TEL's board live all session, with the odds of reaching each level.
TEL's closing options book on October 19, 2026 carried −$200K of net dealer gamma spread across 5 expirations and 23 contracts. The sign is negative, so hedging runs with the move rather than against it.
The heaviest call-side strike sits at 240 and the heaviest put-side strike at 200, a band 19% wide. TEL has averaged 2.64% between its high and its low over the last 89 sessions, which makes the full width of that band about 7.1 average sessions of travel. It closed in the lower third of that band.
TEL closed at 212.33 — 13% below the call wall and 5.8% above the put wall. The put side is the nearer of the two at 5.8% 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.
TEL's apex — the strike carrying the most gamma in absolute terms — is 200, 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.
What TEL's walls are — and aren't
TEL's book has been recorded on 89 sessions. Its average daily range over that stretch was 2.64% 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.

TEL does not have a well-defined gamma flip in the current book.
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 (TEL's book has been recorded on 89 sessions).
