Week of September 1: The Bounce Ran 761 to 7750, Then Sat on 770 / 7720
Four Rank sessions, one corridor. SPY closed 761.60 on September 1, sat on 765 then 773, and finished the week on the $770 0DTE top. SPX tagged 7757 Thursday and closed Friday under 7720. Friday GEX was negative, and 0DTE was 42.9% of SPY gross.
This is a Rank Symbols weekly readout for September 1–4, 2026. Monday September 7 is Labor Day. It is not a trade.
The week had one shape: a low near 761, a Thursday tag of the 7750 0DTE top, then a Friday close back on 770 / 7720 with negative gamma and a fat 0DTE share.
Daily editions: September 2 · September 3.

| Session | SPY OHLC | SPX OHLC | Rank 0DTE close vs structure |
|---|---|---|---|
| Tue Sep 1 | O 762.00 / L 760.70 / H 764.70 / C 761.60 | O 7635.50 / L 7626.10 / H 7663.60 / C 7633.10 | Week low. Volume 20.38M |
| Wed Sep 2 | O 762.50 / L 761.70 / H 766.40 / C 765.30 | O 7634.60 / L 7633.60 / H 7681.20 / C 7669.70 | SPY put wall $765. SPXW 0DTE top 7670 |
| Thu Sep 3 | O 767.90 / L 767.50 / H 774.00 / C 773.20 | O 7686.70 / L 7686.70 / H 7756.80 / C 7747.70 | SPY 0DTE top $773, call wall $774. SPXW 0DTE top 7750 |
| Fri Sep 4 | O 772.00 / H 772.90 / L 769.00 / C 770.20 | O 7741.90 / H 7742.20 / L 7706.10 / C 7718.60 | SPY 0DTE top $770. SPXW 0DTE top 7720. Both books negative |
SPY volume: 20.38M → 14.27M → 41.44M → 32.95M. Thursday was the busy session. Friday was still twice Tuesday.
Friday is the week's evidence, not Thursday's high
Thursday's close under 7750 looked like a pin. Friday opened 7,741.90, never retook the high, and closed 7,718.60. That is a give-back into the next 0DTE map, not a hold of Thursday's top.
SPY 0DTE Friday: close sat on 770
Test app, session 2026-09-04, horizon Today · 0DTE. Callout 1 is the Friday lock: negative gamma, 0DTE 42.9% of all-expiry gross. Callout 2 is close versus the $770 put wall / magnet / 0DTE top. GEX is prior-close structure (T+1). Captured September 7, 2026.
On this snapshot:
- Environment: Negative
- Net GEX: −$2.0B (gross $29.3B)
- Call wall: $771.00
- Put wall / magnet / 0DTE top: $770.00 (74.6% of selected-range gross GEX)
- Flip: $771.90
- 0DTE share of all-expiration gross: 42.9%
- Close: $770.20
All-expiration SPY the same Friday is also negative (net −$4.3B, gross $68.3B), call wall $775, put wall / magnet / 0DTE top $770, flip $771.57. The same-day book is tighter. The 0DTE share is the tell: almost half of Friday's gross GEX was same-day.
SPXW 0DTE Friday: close sat under 7720
Same session, SPXW, horizon Today · 0DTE. Callout 1 is the regime turn: net GEX −$15.8B. Callout 2 is close versus the $7,720 0DTE top. Thursday's high was 7,756.80. Captured in the test app on September 7, 2026.
On this snapshot:
- Environment: Negative (net GEX −$15.8B, gross $89.0B)
- Call wall / magnet / 0DTE top: $7,720 (57.6% of selected-range gross GEX)
- Put wall: $7,715
- Flip: $7,719.83
- 0DTE share of all-expiration gross: 32.3%
- Close: 7,718.60
Wednesday's 0DTE book was positive at 7670. Thursday's was positive at 7750. Friday's is negative at 7720. Mixing those three Fridays-of-structure into one "gamma week" slogan erases the session.

Positive versus negative GEX here is modeled structure, not signed dealer inventory. See Negative GEX is session risk, not a trade.
