How this service works
Dealer gamma exposure (GEX) analysis for any US stock or ETF — returns aggregate GEX, gamma flip level, key pinning strikes, and vol regime signal (positive GEX = pinning, negative = acceleration). Free CBOE delayed data, no API key. Standard SpotGamma-style calculation: calls subtract gamma, puts add gamma. Use with options-snapshot for full options context.
Output
A ranked list of strikes with the highest positive and negative gamma exposure (GEX) for the requested ticker and expiry window, indicating where options dealers are likely to hedge and where price may pin or repel.
