What Would Change My Mind

• If QQQ breaks below $705 on OPEX close and holds sub-$703 into Friday → dealer gamma flips to positive zone, reversing net-seller behavior and removing mechanical rally-fade constraint. • If NVDA sustains a close above $208.50 (past the $207.50 flip level) with IV crush not materializing → short gamma regime loses its highest-conviction hedge anchor, signaling dealer positioning has already rotated. • If SPY closes OPEX above $754 while six-of-eight names simultaneously break their respective short-gamma thresholds → structural dominance inverts from dealer net-seller to net-buyer regime, eliminating the primary downside amplification mechanism.
