What Would Change My Mind

• If SPY closes above the $783.00 gamma flip level for three consecutive sessions before CPI release → dealer short convexity unwinds and positive gamma becomes the marginal constraint, reversing the structural headwind that has defined this regime.
• If QQQ breaks below $740 with volume exceeding 90th percentile → gamma-driven selling accelerates into the $730 support zone, triggering mechanical deleveraging across long convexity positioning that has been hedged against negative gamma.
• If NVDA and AAPL both breach their respective flip levels ($240 and $360) within the same trading session → the 6/8 negative gamma dominance flips to 4/8 or worse, fundamentally reshaping dealer hedging behavior and eliminating the unified structural constraint that has anchored positioning.
