The Problem

Market makers don't trade blind—they trade liquidity, hedging walls, and exposure levels. As a retail trader, trying to calculate Gamma Exposure (GEX), Delta Exposure (DEX), and Vanna Exposure (VEX) manually using stale, end-of-day data is a recipe for getting caught on the wrong side of a squeeze. Existing institutional software that calculates these options exposures costs thousands of dollars a month, trapping you in a laggy web interface.
