Why the 7500 hold failed to pin: the 10 Nov 0DTE close escaped into negative gamma
A narrated teaching recap — November 10: SPX closed on negative gamma between 7520 and 7525, not on the 7500 hold. The warnings were already overhead.
What the 10 Nov recap shows
Tuesday 10 Nov closed on negative gamma, not on the 7500 hold. The film opens on that miss, then walks back through the warnings that were already on the tape.
1. The close. SPX printed 7522.27 at 15:59 ET, between 7520 and 7525, both deep in negative gamma. 7520 was minus 327, the largest negative of the day. The 7500 hold, plus 167 at 14:39 ET, had faded to plus 0.75. Our own end-of-day advisory had called the close at 7500.
2. The warnings overhead. 7520 flipped negative at 13:23 ET and deepened from the call side. Negative strikes stacked right above the 7500 hold. The hold peaked at 14:39 ET, then wobbled. Vanna at 7500 had already flipped negative at 13:59 ET.
3. The day's reads. Early New York, 7550 was the level overhead, while vanna at 7590 and 7550 built large — vanna shows where hedges get sensitive to volatility, not where price must go. Charm under 7500 went negative and built as price churned lower. A 7485-to-7515 scalp looked possible around 13:25 ET and was passed as too thin; 7515 printed later. Market-wide put buying dried up and SPX 0DTE call fuel came in. At 15:44 ET a close on 7510, a negative-gamma strike, was in view — a close on negative gamma is not a pin.
The lesson: a big positive hold below does not pin price if a negative ladder is building right above it. Watch the strikes overhead, not just the support.
