Mechanical support & resistance.
Strikes where dealers hold the most positive or negative gamma act as price magnets. The Call Wall is where dealers aggressively hedge by selling rallies — the ceiling the market has to fight through. The Put Wall is the floor they defend by buying dips.
- Highest net positive GEX = Call Wall (resistance)
- Most negative net GEX = Put Wall (support)
- Toggleable as horizontal lines on the price chart
- Highlighted in the strike table with colored borders
The volatility pivot most traders ignore.
Above the flip, dealer hedging dampens moves and the market grinds. Below it, hedging amplifies moves and price action accelerates. Crossing the flip from above is one of the cleanest regime-change signals in options markets.
Our gamma flip is computed via linear interpolation across the exact strike where cumulative net GEX crosses zero — not just rounded to the nearest strike.
