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 ALL gamma exposure
The business exposure behind ALL includes property and casualty insurance. That connects the options chain with underwriting, claims, pricing, and investment income. Compare the positive and negative GEX bars by strike instead of reading one wall without the rest of the selected profile.

ALL GEX methodology and limitations
QuantWheel calculates ALL 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.
ALL GEX FAQ
What is ALL GEX?
ALL GEX estimates gamma exposure across listed ALL options using option gamma and open interest. It helps you compare how modeled exposure is distributed by strike and expiration. ALL GEX does not reveal actual dealer positions or predict where ALL will trade.
How do I read the ALL call wall and put wall?
QuantWheel labels the ALL call wall as the strike with the largest positive modeled GEX and the ALL put wall as the strike with the largest negative modeled GEX in your selected data. Compare both with the ALL price and expiration choices. They are reference levels, not guaranteed support or resistance.
What is the ALL gamma flip?
The ALL gamma flip is the price where modeled net gamma crosses zero for the selected ALL options data. Compare it with the current price and the shape of the strike chart. The ALL gamma flip is a model output, not a trading signal.
Which expirations should I use for ALL GEX?
Start with the nearest ALL expiration to study short-dated positioning, then add later expirations to compare a broader part of the options chain. Each selection changes which ALL contracts are included, so compare one expiration with a combined view before drawing conclusions.
Is the ALL GEX calculator free?
Yes. You can run up to three free ALL 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.
