NetGEX on $SPY flipped from +256k to -51k about 20 minutes after the open, last night's earnings are the likely driver. 771 is the 0DTE king and it's negative, so it should keep pulling price toward it and stretching moves. 770 is the floor, not a strong one but still a quant level, below that 770-768 is slide-regime territory where we don't want lower lows.
