📊 GEX Profile

• Horizontal bars — one per strike, length proportional to net GEX concentrated at that strike. Strikes run top to bottom, so the profile sits alongside price.
• Positive GEX (green) — strikes where dealers are net long gamma. These tend to dampen moves as price approaches.
• Negative GEX (orange) — strikes where dealers are net short gamma. These tend to amplify moves and accelerate trends.
• Spot line — marks the current price across the profile, so every level is read relative to where price is now.
• Structural levels — the Gamma Flip, Call Wall, Put Wall, HVL (high-volume / volatility pivot level) and γ Support are labeled directly on the chart and can be toggled from the header.
• GEX and DEX overlays — line overlays trace the cumulative gamma (GEX) and delta (DEX) profiles on top of the bars for added context.

A toggle in the header switches between two readings of the same data:

• Net — one signed bar per strike (call gamma minus put gamma), the cleanest read of where dealer hedging pressure concentrates.
• Call/Put — splits each strike into its call-side and put-side gamma so you can see which contracts are driving a level rather than only the net result.

Alongside the chart, a side panel translates the profile into a plain-English read of the current environment — a regime label (for example, "Cautious Bullish"), a confidence note, and a short narrative explaining the trading range, where the walls sit, and how dealer hedging is likely to behave around spot. A compact legend maps each level to its meaning, such as the Put Wall as cascade risk or γ Support as a positive-gamma floor.

Click any bar to open a popup with the contract-level breakdown at that strike: call / put open interest, gamma, premium, and implied volatility. On touch devices, tap a bar to inspect, pinch to zoom, drag to pan, and double-tap to reset.
