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 CRH gamma exposure
CRH is classified in Construction Materials within Materials. CRH options can respond to company earnings and changes in project demand, backlog, labor availability, and material costs. Use the GEX chart to see whether modeled positive and negative exposure is concentrated at a few strikes or spread across the selected chain.

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