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 DVA gamma exposure
The DVA options chain represents DaVita and its exposure to product demand, regulatory decisions, clinical developments, and reimbursement trends. Its GICS classification is Health Care Services. Use the chart to identify where modeled exposure is concentrated and whether that concentration is consistent across expiration choices.

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