Each row is a strike, summed across ALL expiries in the window above (front ~3 weeks of the board — not 0DTE, not a single expiry). Bar = net dealer gamma at that strike (green right = positive/pinning, red left = negative/amplifying). Put OI / call OI show where contracts are actually open — the positioning distribution behind the walls. Highlighted row ≈ spot.
