DELL is currently in negative gamma, with the zero-gamma flip near 327.52. Negative gamma means dealers amplify moves — a trending, more volatile tape where dips and rips extend.
DELL's zero-gamma flip is around 327.52 — the price where net dealer gamma crosses zero. Above it the tape tends to be positive-gamma (suppressed, range-bound); below it, negative-gamma (amplified, trending). Reclaiming or losing the flip is the single most important level on the map.
DELL's call wall (420) is a magnet and resistance; the put wall (382.5) is support in positive gamma but a through-level once price is below the flip.
DELL's max pain is 395 — the strike where the most options expire worthless. In a positive-gamma tape, price often gets drawn toward max pain into expiration.
