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

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