Tuesday’s map answered a question Monday’s could not: where exactly does the tape stop being friendly? The 0DTE gamma profile crossed from positive to negative between $723 and $722, and the gamma flip level had jumped more than eight points closer to price overnight. That is a defended zone with an edge you can name — and a spread you can sell underneath it.
Total GEX rose $4.6B (+24.1%) to $23.7B. Gross positioning was rebuilt on both sides overnight; the walls themselves did not move.

Values the panels did not expose are omitted rather than estimated.
Spot was $722.81, down 24 cents. Net GEX rose to +$3.99B (+9.0%), but the interesting move was gross: call GEX up $2.5B to $13.9B (+21.9%), put GEX $2.2B more negative at -$9.9B, total GEX up $4.6B to $23.7B (+24.1%). The call wall stayed $730 and the put wall stayed $660.
Zero gamma went from $706.68 to $715.10 — up $8.42. (Monday's own 7:20 AM brief printed $707.18; this comparison is against the 9:00 ET capture, hours apart. Neither figure is adjusted here.) That single number did two opposite things at once. It made the pinning structure above the line stronger, and it turned $715 into a much more important trigger, because the cushion beneath the market shrank from roughly sixteen points to under eight.
The page exposed 17 of 530 strikes, covering roughly $717-$730 — not the full range. Separate call and put totals were not exposed per strike, so a negative bar is labelled negative net GEX rather than presented as pure put gamma.

Read it top to bottom. From $730 down to $723, every strike carried positive 0DTE gamma — a shelf, with $726 (+$152.5M), $725 (+$151.7M) and $723 (+$104.8M) as the heaviest planks. At $722 the sign flips, and it stays negative all the way to $717 (-$64.8M), the largest visible downside node.
Above $723, dealer hedging leans against movement. Below $722, it stops helping and the negative pockets start doing the opposite. That is not a directional forecast. It is a statement about where the character of the tape changes — and that is exactly what a spread seller needs.
The morning framing was 714/716. The fill, at 9:42 AM, was a 100-lot 715/720 put spread expiring Aug 14, with the stated plan to hedge it overnight. Worth stating plainly: the posted idea and the executed strikes were not identical.
What makes the structure fit the map:
The skew was doing the spread seller a favor:
| Measure | Aug 11 reading | What it means for a put spread |
|---|---|---|
| 0DTE ATM IV | 16.7% at strike 723 | Up from 12.1% the prior day — more premium available |
| 25∆ skew | +10.7 vol points | Puts rich; real demand for downside protection |
| 25∆ references | 717P 22.1% vs 726C 11.4% | Nearly double the implied vol on the side you are selling |
| 25∆ butterfly | +0.1 points | Little curvature — the skew is a tilt, not a kink |
| Term slope | +1.9 points | Near expiry still cheaper than the Aug 12 CPI expiry |
The large-capital strangle was left alone, because the call side never got pressured. It produced $871 over the weekend and another $377 on Monday — consistent with the stated expectation of 10-12% a month on larger capital. A new leg went on in the same train: 655p/780, September 25 expiration.
The $1,412 on the primary strangles was almost 2% in a day on 72K of buying power, against a stated standard of about 0.5%. Reported figures from the desk’s own end-of-day recap; the losing line is included for the same reason the winners are.
Three strategies, two green, one red. The Kite took two entries — one bull, one bear — for +$4,465. The primary strangles made $1,412 on 72K of buying power, close to 2% in a day against a stated standard of about 0.5%. Gamma scalping lost $1,678 across four trades, three bull and one bear.
The individual legs show why the scalping line is negative:
| Leg | Qty | Trade | Close | P&L | ROI |
|---|---|---|---|---|---|
| QQQ 720 long put · Aug 11 | 100 | 1.06 | 1.88 | +$8,160 | +76.8% |
| QQQ 723 long call · Aug 11 | 100 | 0.86 | 0.49 | -$3,675 | -42.7% |
A 76.8% winner and a 42.7% loser in the same session, on the same underlying, hours apart. That is the honest texture of trading the fast side of a pinned range.
CPI was one session away. Net GEX was positive, ATM IV had risen, downside skew was very rich — and none of that addresses an 8:30 AM print. Oil was an active overlay: Reuters had Brent up roughly 2% after a 5% prior-session surge on the U.S.-Iran impasse, with VIX around 15.5 and the 10-year near 4.72%.
A 100-lot QQQ 715/720 put spread expiring Aug 14, sold at 9:42 AM ET, with the stated intention to hedge it overnight. The morning note had framed the same idea as a $25K vertical at 714/716 before the fill went on at 715/720.
The short strike sits under the level where dealer hedging stops dampening moves. Above the flip, hedging works with the position; the spread only comes under real pressure once price trades into the zone where that support disappears — and the long wing caps the loss if it does.
No. On Aug 11 the 25-delta skew was +10.7 vol points with the 717 put at 22.1% against the 726 call at 11.4%. That premium exists because demand for downside protection is real. Getting paid more for the same distance is an edge in pricing, not a reduction in risk.
