GEX ICT FVG/IFVG

Gamma exposure (GEX) in finance refers to the collective sensitivity of market makers to price changes, indicating whether they need to buy (stabilizing) or sell (amplifying) an asset as its price moves, impacting volatility and potential price ranges, especially around key option strike prices; it's a key indicator for options traders, contrasting with the physical hazard of gamma rays. High positive GEX means market makers buy low/sell high (dampening moves), while negative GEX means they buy high/sell low (amplifying moves), often leading to "gamma pinning" near expiration.
