Free COST GEX Heatmap - Costco Gamma Exposure
Use free COST GEX Heatmap to compare modeled gamma exposure across strikes and expirations for Costco. Generate the grid, then review call wall, put wall, gamma flip and expiration structure alongside business context that includes product demand, regulation, company results, and customer spending.
How to use the COST GEX Heatmap
Confirm COST
COST is already entered. Keep it or search another ticker.
Choose the formula
Keep the default formula or select the available calculation view.
Generate the Heatmap
Create the grid, then compare exposure across strikes and expirations.
Visualize gamma exposure across strike prices and expirations. Green = positive (call-heavy), purple = negative (put-heavy).

Open GEX WorkspaceUnderstanding the COST GEX heatmap
The COST options chain represents Costco. Evaluate its open-interest distribution alongside business context that includes product demand, regulation, company results, and customer spending. Use the heatmap to compare modeled exposure by strike and expiration instead of reading one cell without the surrounding grid.
For COST, 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 Costco will trade.
COST Heatmap methodology and limitations
The grid applies the selected formula to available COST 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 COST move. Use it as positioning context and compare the model with price, liquidity and your own risk plan.

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