SPX Market Maker Gamma Profile 🛫
all expiry 1st pic, 0dte 2nd pic
7500 has a ton of market maker Long Calls piled up that require selling futures to hedge an increase in delta if spot price rises toward the strike. currently that's our largest pile of gamma, delta moves quickly at that strike. if we can break thru 7505 & then 7525, there is oxygen to fuel a run toward 7550. in 0dte, 7505 is a magnet of positive vanna, waiting for IV to drop, but also a resistive force against a spot move higher as market makers sell to hedge their positive deltas. below spot, lose 7465 & it's 7450 then 7430. a crash takes us to 7400 where customers are Long lotsa Puts, forcing market makers to sell to hedge their book exposure, accelerating a move lower with the help of positive vanna. however, as the day grinds on, negative charm will help to buoy at the strike.
