Real-time Gamma Exposure (GEX) analytics for SPY options. See where market makers are forced to hedge — and trade with the structural edge that institutions see.
When market makers sell options, they inherit gamma exposure. To stay delta-neutral, they must continuously buy and sell the underlying — creating invisible zones of structural support and resistance that most traders never see.
Positive gamma territory: dealers buy dips and sell rallies, dampening volatility and pulling price toward large gamma concentrations.
Negative gamma territory: dealers buy when price rises and sell when it falls — amplifying every move, accelerating breakouts, and increasing realized volatility.
GEXBoard decodes this positioning in real time. Know the Gamma Flip level, the Call and Put Walls, and whether dealers are working for you or against you — before you place a trade.
