Free FDS GEX Heatmap - FactSet Gamma Exposure
Use free FDS GEX Heatmap to compare modeled gamma exposure across strikes and expirations for FactSet. Generate the grid, then review call wall, put wall, gamma flip and expiration structure alongside business context that includes interest rates, credit conditions, commodity prices, and company results.

These are the levels across every expiration in the latest snapshot. The heatmap below breaks the same exposure out strike by strike and expiration by expiration, so you can see which expiry carries each level.

Understanding the FDS GEX heatmap
The FDS options chain represents FactSet. Evaluate its open-interest distribution alongside business context that includes interest rates, credit conditions, commodity prices, and company results. Use the heatmap to compare modeled exposure by strike and expiration instead of reading one cell without the surrounding grid.
For FDS, compare nearby expiration columns with later expirations before interpreting the call wall, put wall or gamma flip. Changes in open interest and included contracts can alter the modeled grid. The result describes selected options data and does not predict where FactSet will trade.
FDS Heatmap methodology and limitations
The grid applies the selected formula to available FDS options data and organizes the modeled result by strike and expiration. The call wall, put wall and gamma flip summarize that model across the displayed data.
The heatmap does not observe market-maker positions, identify who owns a contract or predict the next FDS move. Use it as positioning context and compare the model with price, liquidity and your own risk plan.
FDS GEX heatmap FAQ
What is a FDS GEX heatmap?
A FDS GEX heatmap is a grid of QuantWheel's modeled gamma exposure. Rows represent strikes, columns represent expirations, and color intensity represents the direction and relative size of the modeled exposure in each cell.
How do I read the FDS GEX heatmap?
Start with strikes near the FDS price, then compare the nearest expiration columns with later expirations. Read down one column to examine one expiration and across one row to see whether modeled exposure at a strike appears in several expirations.
What do the FDS GEX heatmap colors show?
Green cells show positive modeled net gamma and purple cells show negative modeled net gamma. Stronger color indicates a larger modeled value. The colors describe the calculation and are not guaranteed bullish, bearish, support, or resistance signals.
How are the FDS call wall, put wall and gamma flip modeled?
QuantWheel derives the displayed FDS levels from the selected formula and available options data. The call wall marks the largest positive modeled exposure, the put wall marks the largest negative modeled exposure, and the gamma flip estimates where aggregate modeled gamma changes sign.
How is the FDS GEX heatmap different from the FDS GEX chart?
The FDS heatmap separates modeled exposure by strike and expiration. The FDS GEX chart provides a strike-level profile in a chart view. Use the heatmap when the expiration breakdown matters and the chart when you want a simpler strike profile.
Is the FDS GEX heatmap free?
Yes. QuantWheel provides a limited number of free FDS GEX heatmap calculations. The tool shows the remaining free uses before you generate another heatmap.
