Understanding the WTW GEX heatmap
The WTW options chain represents Willis Towers Watson. Evaluate its open-interest distribution alongside business context that includes underwriting, claims, pricing, and investment income. Use the heatmap to compare modeled exposure by strike and expiration instead of reading one cell without the surrounding grid.
For WTW, 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 Willis Towers Watson will trade.
WTW Heatmap methodology and limitations
The grid applies the selected formula to available WTW 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 WTW move. Use it as positioning context and compare the model with price, liquidity and your own risk plan.
WTW GEX heatmap FAQ
What is a WTW GEX heatmap?
A WTW 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 WTW GEX heatmap?
Start with strikes near the WTW 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 WTW 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 WTW call wall, put wall and gamma flip modeled?
QuantWheel derives the displayed WTW 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 WTW GEX heatmap different from the WTW GEX chart?
The WTW heatmap separates modeled exposure by strike and expiration. The WTW 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 WTW GEX heatmap free?
Yes. QuantWheel provides a limited number of free WTW GEX heatmap calculations. The tool shows the remaining free uses before you generate another heatmap.
