📡 WHAT IS GAMMA EXPOSURE (GEX)?
GEX measures how much options dealers must buy or sell the underlying stock to stay hedged as price moves. High positive GEX acts like a magnet — dealers buy dips and sell rips, pinning price. Negative GEX does the opposite, amplifying moves.
GravityGEX calculates this in real time from live CBOE options data. Pick a ticker on the left and the analysis loads automatically — no API key needed.
+ GEX → dealers pin price
− GEX → dealers amplify moves
Gamma flip = regime transition level
