What is Gamma Exposure (GEX)?
Gamma Exposure represents the sensitivity of an option's delta to changes in the underlying price. Market makers hedge their gamma exposure, creating support/resistance at high GEX strikes.
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX, shown as the deepest negative bar (support)
- Gamma Flip: Where total GEX changes from negative to positive
Positive GEX: Market makers sell into rallies, buy into dips (stabilizing).
Negative GEX: Market makers buy into rallies, sell into dips (amplifying moves).

Understanding FANG gamma exposure
Diamondback Energy is classified in Oil and Gas Exploration and Production within Energy. FANG options can respond to company earnings and changes in oil and gas prices, production, capital spending, and energy demand. Use the GEX chart to see whether modeled positive and negative exposure is concentrated at a few strikes or spread across the selected chain.

FANG GEX methodology and limitations
QuantWheel calculates FANG GEX from the selected expirations, available options data and the formula displayed in the calculator. The result summarizes modeled gamma exposure by strike.
GEX is a model output, not observed dealer inventory or a price forecast. Open interest does not identify who owns an option, and the displayed call wall, put wall and gamma flip can change when the inputs or selected expirations change.
FANG GEX FAQ
What is FANG GEX?
FANG GEX estimates gamma exposure across listed FANG options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. FANG GEX does not reveal actual dealer positions or predict where FANG will trade.
How do I read the FANG call wall and put wall?
QuantWheel labels the FANG call wall as the strike with the largest positive modeled GEX and the FANG put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the FANG price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the FANG gamma flip?
The FANG gamma flip is the price where modeled net gamma crosses zero for the selected FANG options data. Compare it with the current price and the shape of the strike chart. The FANG gamma flip is a model output, not a trading signal.
Which expirations should I use for FANG GEX?
Start with the nearest FANG expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which FANG contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the FANG GEX calculator free?
Yes. You can run up to three free FANG GEX calculations per day on the public tool. After using those calculations, continue for free in the GEX demo. Check the current QuantWheel pricing page for plan access details.
