SPY Weekly Options Positioning Map: 710 Wall, 700 Floor, 675 Deeper SupportNeutral

SPY is sitting directly on the 710 gamma wall after a +4.8% week. Aggregate gamma is now strongly positive, monthly positioning flipped from negative to positive, and the near-term range tightened to 700-710. Spot is 3.2% above max pain (688), the widest dislocation in weeks. Watch the 706 GEX flip below spot.

SPY Weekly Scorecard: April 13 - 17Neutral

Grading last week's chain map. The 685 pivot was taken out Tuesday. The 700 ceiling was gone by Thursday. The 660 floor was never threatened. Neutral bias missed a +4.8% rally, the third straight week the vanna mechanism was called correctly but underweighted in the headline.
