Dealer DEX Surface (Spot: $600)

25 x 15 grid

Delta Neutral Levels

Delta flip detected near strikes: $610. These levels mark where dealer net delta flips sign — dealer hedging flows may reverse direction here.

Positive DEX (Blue)

Dealers are net long delta. To stay delta-neutral they may sell the underlying into strength, creating natural resistance and dampening upside moves.

Negative DEX (Red)

Dealers are net short delta. To hedge they must buy the underlying, providing a tailwind beneath the market and potentially accelerating upside moves as spot rallies.

Delta Walls

Large DEX concentrations at specific strikes create dealer hedging walls. Heavy positive DEX above spot can cap rallies; heavy negative DEX below can provide support floors.
