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 PFE gamma exposure
The PFE chart organizes QuantWheel's modeled Pfizer gamma exposure by strike. Compare positive and negative bars across the selected expirations before interpreting the call wall, put wall or gamma flip.
Use the PFE profile to identify where the selected model is concentrated and how it changes when expirations change. The result describes the options data included in the calculation and is not a forecast or standalone trading signal.

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