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 SNA gamma exposure
The business exposure behind SNA includes industrial machinery and supplies and components. That connects the options chain with orders, production, capital spending, and end-market demand. Compare the positive and negative GEX bars by strike instead of reading one wall without the rest of the selected profile.

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