Gamma Topography
Recorded gamma across session time and price, rendered as an interactive landscape of positive ground, negative canyons and the zero boundary.
Gamma Topography turns the recorded session gamma field into interactive 3D terrain. Positive gamma rises above the zero plane, negative gamma cuts below it, and the white line follows the boundary between the two. The blue line traces recorded price across the landscape.
This is another view of the same session inventory shown by Exposure Gradient, not a price forecast. If a session has no recorded intervals yet, the widget stays unavailable instead of drawing a hypothetical future surface.
Controls#
| Control | What it changes |
|---|---|
| 0DTE / 1DTE / All | Nearest expiry, next expiry, or the full available chain |
| Positioning | Open-interest inventory or session-volume positioning |
| Height | How strongly quiet and extreme areas are separated visually |
| Range / opacity | Price window and terrain transparency |
| Contours | Equal-height lines projected across the terrain |
| Zero coast / plane | The sign-change boundary and its reference plane |
| Price path | Recorded price placed on the terrain |
| Grid / scale | Scene guides and the long/short color key |
Drag to orbit, scroll to zoom and right-drag to pan. The widget remembers its camera separately for each symbol, expiry scope and positioning view. Reset view returns to the default angle.
How to read it#
- High ground is a positive-gamma area; canyons are negative-gamma areas.
- A stable ridge at one price shows gamma remaining concentrated there across several recorded intervals.
- A moving coastline shows the neutral boundary shifting during the session.
- Compare the blue price path with the terrain to see which regime price actually crossed. The landscape describes recorded positioning and does not predict the next path.
Recorded gamma, delta pressure and charm pressure across strike and session time.
How dealer exposure built up at each strike through the session, in time buckets, with price on top.
What positive and negative gamma mean for price, and how to read the regime badge.
The price where dealer gamma turns from positive to negative, and why it matters.
