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).
Select a ticker and expiration date, then click Generate GEX to see the analysis

Understanding NOC gamma exposure
Northrop Grumman is classified in Aerospace and Defense within Industrials. NOC options can respond to company earnings and changes in aircraft or defense demand, production, contracts, and government spending. Use the GEX chart to see whether modeled positive and negative exposure is concentrated at a few strikes or spread across the selected chain.
The NOC call wall, put wall, and gamma flip depend on the contracts included in the calculation. Recompute the chart after changing expirations and compare the distribution around the current price. The output is positioning context rather than a forecast.

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