The longer $SPX holds 7,500, the more this looks like a retest of Monday's breakout rather than a full reversal.

Anyone who bought 0DTE and 1DTE puts yesterday betting on a drop to 7,400–7,450 is now underwater. Classic gamma squeeze in reverse — short-dated puts getting crushed as the floor holds.

That's options flow for you. The circle of life, but with theta decay.
