SPY 0DTE

SPY Near gamma flip — transition

2026-08-20

Regime

Transition Near Flip

Bias

Neutral

Range

760-775

Gamma flip: 765.50
Call wall: 775
Put wall: 760

SPY 764.58 — dealers in flux near the gamma flip at 765.50. Tight range expected. 760 holds → base case, chop between walls. Breaks down → rotation lower. 775 breaks up → drift toward overhead pocket. Iron condors and credit spreads are traps here; dealer pinning is unpredictable. Debit spreads (calls or puts) fit only after directional confirmation. Wait for acceptance outside 760–775 before sizing in. This is a tape that punishes early structure.

SPX 0DTE

SPX Near gamma flip — transition

2026-08-20

Regime

Transition Near Flip

Bias

Neutral

Range

7,700-8,000

Gamma flip: 7,718.98
Call wall: 8,000
Put wall: 7,700

SPX at 7708, dealers net short gamma — transition zone. Behavior flips unpredictably near 7719. 7700 holds → base case, range-bound chop. 7700 breaks → rotation lower. 8000 holds → overhead friction. 8000 breaks → drift higher. Debit spreads (calls or puts) fit only after directional confirmation. Iron condors and credit spreads stay off the table — dealer flow too unstable here. Wait for price to claim a level, then size in. Don't chase into the flip.
