Disclaimer & Data Notes: This heatmap uses a naive GEX model — a more open approach to Gamma Exposure calculation. Flow GEX uses intraday volume as a proxy for dealer positioning; Position GEX uses end-of-day open interest. Neither model accounts for whether each contract was customer-bought or dealer-sold (exchange-tagged flow), which is the primary difference between this tool and drastically more expensive services like Heatseeker. As a result, signs on individual strikes may differ from premium platforms. The Market Structure Summary is auto-generated for educational purposes and should not be relied upon solely for making financial decisions. Always conduct your own research and consider your individual risk tolerance before trading.
