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 WTW gamma exposure
WTW provides options exposure to Willis Towers Watson, which operates in insurance brokers. Earnings and shifts in underwriting, claims, pricing, and investment income can change option pricing and open interest. The GEX chart shows how modeled exposure is distributed for the contracts and expirations you include.
For WTW, compare a single expiration with a combined view before interpreting the call wall, put wall, or gamma flip. Changes in open interest and the contracts selected can shift the modeled profile. These levels describe the selected options data and do not predict where Willis Towers Watson will trade.

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