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).

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