Understanding the SPG GEX heatmap
The SPG options chain represents Simon Property Group. Evaluate its open-interest distribution alongside business context that includes Simon Property Group, which operates in retail reits. Use the heatmap to compare modeled exposure by strike and expiration instead of reading one cell without the surrounding grid.
For SPG, 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 Simon Property Group will trade.
SPG Heatmap methodology and limitations
The grid applies the selected formula to available SPG 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 SPG move. Use it as positioning context and compare the model with price, liquidity and your own risk plan.

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