September 9 Findings: Close Sat on 762 / 7635
Rank Symbols on the completed September 9 session shows SPY closing 762.40 on the $762 0DTE put wall, under the $763 top. SPXW opened at the high, never retook it, and closed 7636.40 on the 7635 0DTE top. Both books were negative.
This is a Rank Symbols readout of the completed September 9, 2026 session. It is not a trade.
Two clocks sit on the same screen:
- Session OHLC — what printed that day.
- TradingFlow GEX — that session's prior-close structure (T+1). It does not recompute live 0DTE books.
The session sat on 762 / 7635. That is the finding. Friday's week-of-Sep-1 close on 770 / 7720 did not survive the two sessions after Labor Day.
Session tape versus T+1 structure. GEX levels are prior-close. Price bars are that session. Neither row is a forecast.

Test app, session 2026-09-09, horizon Today · 0DTE. Callout 1 is the lock: negative gamma, 0DTE 14.7% of all-expiry gross. Callout 2 is close versus the $762 put wall and $763 0DTE top. GEX is prior-close structure (T+1). Captured September 10, 2026.
On this snapshot:

- Flip: $766.43
- 0DTE share of all-expiration gross: 14.7%

SPXW 0DTE: close sat on 7635
Cash SPX 0DTE lives on SPXW. Same session, horizon Today · 0DTE:
Same session, SPXW, horizon Today · 0DTE. Callout 1 is the concentration: 7635 is 52.5% of selected-range 0DTE gross. Callout 2 is close versus that top. Structure built 5:40 PM EDT. Captured in the test app on September 10, 2026.

Half of this 0DTE book's selected-range gross sits on 7,635. Close was one point above it. The session low (7,624.20) ran through it and came back. That is a sit on the T+1 top, not a hold of Thursday's 7,750 or Friday's 7,720.

| Did 770 / 7720 survive after Labor Day? | Sep 8 close 766 / 7673; Sep 9 close 762 / 7636 | Two session OHLC bars |
Negative GEX here is modeled structure, not observed dealer inventory. See Negative GEX is session risk, not a trade.

- Change symbol to SPXW. Keep horizon Today · 0DTE. Record the 0DTE top, put wall, and flip. Confirm the structure timestamp (this run: 5:40 PM EDT).
- Optionally switch SPY to All expirations and note the put wall moves to $760 while the 0DTE top stays $763.
- Stop before "therefore the next session pins 762."
