As of the latest session, TLT is trading at $81.85 (+0.01% on the day). Net dealer gamma is negative, with the zero-gamma flip near 82.02. The call wall sits at 81.5 (upside magnet / resistance) and the put wall at 82 (downside level). Max pain is 82, and the options market is pricing a 1-sigma expected move of about ±0.6% (ATM IV 16%).
TLT is trading below its zero-gamma flip. Spot 81.85 sits −0.21% under 82.02, which puts dealers on the wrong side of their hedges: staying neutral forces them to sell weakness and buy strength. That is the mechanical reason moves in TLT are extending rather than fading right now. Until 82.02 is reclaimed and held, treat every level below as a through-level rather than support.
The book leans mildly upward: +$300M of positive gamma above spot versus +$165M below, a 1.8-to-1 tilt. Enough to bias drift toward 81.5, not enough to call it a magnet.
One strike dominates the map: 81.5, carrying +$165M per 1% move — below the current price. Positive gamma that size behaves like a wall: rallies into it get sold by hedging flow, and dips toward it get bought.
Options are cheap here: ATM implied volatility is just 16%, pricing only ±0.6% (±$0.49) to the nearest expiry. When implied vol is this compressed against a positive-gamma book, buying optionality costs little — and it is usually compressed because the hedging flow has been suppressing realised movement.
Note that TLT has already traded through its call wall at 81.5 (−0.43% away). Past the wall, that positive gamma stops acting as a magnet and starts acting as a cap — the pull that carried price here is now the thing resisting it. The 82–81.5 band spans -0.6% of spot.

TLT is in negative gamma — spot is −0.21% below the 82.02 flip. Dealers amplify moves at these levels, so TLT trends rather than pins, and downside levels behave as through-levels instead of support.
About −0.21%, which is roughly -0.3× the ±0.6% the options are pricing for one session. Under 1× means the flip is reachable in a normal day; over 2× means the regime is unlikely to change without a catalyst. We track this across every major index on the free regime dashboard.
TLT's flip is 82.02, with spot at $81.85. Price is under it, so TLT needs to reclaim 82.02 and hold it to get back into the suppressed regime — roughly -0.3× a single session's expected move away, which is why the level matters more than any moving average on the chart right now.
TLT's call wall (81.5) is a magnet and resistance; the put wall (82) is support in positive gamma but a through-level once price is below the flip.
82, for the 2026-09-18 expiry — expiring today. Spot is $81.85, so max pain sits 0.2% above the current price. In negative gamma the pull is weak: dealers are amplifying moves, not damping them toward a strike.
About +295M per 1% move into the 2026-09-18 expiry — though spot is below the zero-gamma flip, so hedging at this price runs with the move and adds to it. GEX describes the character of the tape, not the direction. How dealer gamma works →
