Free FIS GEX - Live FIS Gamma Exposure
Free FIS GEX shows where modeled gamma exposure is concentrated in FIS options. Change expirations to compare the call wall, put wall, gamma flip, and strike profile around payment volumes, consumer spending, merchant activity, and transaction pricing.

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 FIS gamma exposure
FIS provides options exposure to FIS, which operates in transaction and payment processing services. Earnings and shifts in payment volumes, consumer spending, merchant activity, and transaction pricing can change option pricing and open interest. The GEX chart shows how modeled exposure is distributed for the contracts and expirations you include.

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