Cushion = distance from spot to the zero-gamma flip, and in brackets that distance measured in the index's own expected move for the day. Under 1× means the flip is inside a single normal session. Negative means price is already through it. What is dealer gamma? →
Spot sits above the zero-gamma flip with distance still to the call wall. R:R is room up to the wall divided by room down to the flip.
