One strike caps the day
The story
- 0DTE net gamma positive 94% of minutes, all-expiry 98%. A positive-gamma day from start to finish.
- 10:06 — 7700 went from +$0.44B to +$5.18B in a minute and led the board.
- Price came within 0.68 of it at 11:18 and no closer for 4 hours 40 minutes while it grew to +$17.9B.
- Net premium stayed between -$9M and +$2M all day. No directional flow — a pin, not a fight.
- Then what: 7700 drained from +$15.4B to +$1.8B between 14:21 and 14:42, and price left within five minutes.
