About the Gamma Exposure Dashboard

The GEX Horizon gamma exposure dashboard provides derivatives day traders and quantitative institutions with an aggregate view of options market maker delta obligations. When options contracts are traded, dealers must maintain delta-neutral books by executing offsetting trades in the underlying futures or spot markets. Aggregating these hedging adjustments across all active expirations and strikes forms the basis of our GEX indicator model.

Understanding Option Hedging Levels

Our gamma exposure dashboard isolates three critical indicators:

  • Call Wall: The strike price containing the largest positive concentration of net call option gamma. The Call Wall acts as a formidable ceiling for price action due to dealer delta rebalancing (selling spot shares to hedge as price rises).
  • Put Wall: The strike price containing the largest negative/put options gamma. The Put Wall acts as a key support floor because dealers must buy spot shares to offset short positions as the price declines near this boundary.
  • Zero Gamma Flip: The precise price level where net market maker gamma transitions from positive to negative. Trading above the flip represents a positive gamma regime, while trading below it indicates a negative gamma regime.

How Dealer Rebalancing Impacts Intraday Volatility

In a positive gamma regime, dealer hedging is mean-reverting (buying low and selling high), which effectively dampens intraday price swings. In a negative gamma regime, dealer hedging turns pro-trend (selling low and buying high), which drains liquidity and accelerates price runs, leading to rapid trend expansions. Monitoring these volatility shifts on the dashboard allows day traders to adjust risk parameters in real-time.
