The bullish stack

The story

  1. 0DTE net gamma was positive in 99% of minutes. The day never had room to fall far.
  2. 09:46 — 7750 took the lead on the board at +$3.2B, almost all calls, and charm at spot turned negative, which is the supportive side.
  3. 11:00 to 11:23 — call premium went from -$2.1M to +$4.9M while put premium went from -$0.3M to -$8.3M. Calls bought, puts sold, together.
  4. In the same 23 minutes the 0DTE net delta line went from +$1.4B to +$10.7B, its high of the day to that point.
  5. Price went 7711 to 7747 by 11:30 and then spent four hours under 7750 while that strike grew to +$49B.
  6. Then what: the largest positive strike of the day was the target and then the ceiling. High 7756.76, close 7747.59.
