Free CMI GEX Heatmap - Cummins Gamma Exposure
Use free CMI GEX Heatmap to compare modeled gamma exposure across strikes and expirations for Cummins. Generate the grid, then review call wall, put wall, gamma flip and expiration structure alongside business context that includes project demand, backlog, labor availability, and material costs.
What is a GEX Heatmap?
A GEX heatmap shows net gamma exposure across many strikes and expiration dates in one color-coded grid. Each cell is the net gamma at one strike for one expiration.
Cell Colors:
- Green: Positive gamma (call-dominated strikes)
- Purple: Negative gamma (put-dominated strikes)
- Stronger color means more gamma at that point
Key Levels:
- Call Wall: Strike with highest positive GEX (resistance)
- Put Wall: Strike with the largest put GEX (support)
- Gamma Flip: Where total GEX changes from negative to positive

Understanding the CMI GEX heatmap
The CMI options chain represents Cummins. Evaluate its open-interest distribution alongside business context that includes project demand, backlog, labor availability, and material costs. Use the heatmap to compare modeled exposure by strike and expiration instead of reading one cell without the surrounding grid.
For CMI, 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 Cummins will trade.
CMI Heatmap methodology and limitations
The grid applies the selected formula to available CMI 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 CMI move. Use it as positioning context and compare the model with price, liquidity and your own risk plan.

CMI GEX heatmap FAQ
What is a CMI GEX heatmap?
A CMI 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 CMI GEX heatmap?
Start with strikes near the CMI 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 CMI 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 CMI call wall, put wall and gamma flip modeled?
QuantWheel derives the displayed CMI 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 CMI GEX heatmap different from the CMI GEX chart?
The CMI heatmap separates modeled exposure by strike and expiration. The CMI 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 CMI GEX heatmap free?
Yes. QuantWheel provides a limited number of free CMI GEX heatmap calculations. The tool shows the remaining free uses before you generate another heatmap.
