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 NOW gamma exposure
ServiceNow trades at one of the highest nominal share prices in software, which shapes its gamma exposure in a specific way: strike intervals are wide, contract premiums are large, and casual retail speculation is largely priced out. What remains is institutional flow - earnings positioning, hedges on concentrated software allocations, and systematic overwriting - which gives NOW a gamma profile that moves deliberately rather than violently.

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