# depth

Top-left panel. Five tabs for deep market analysis: Book, Chart, Models, 3D, and Calibrate.

{% tabs %}
{% tab title="Book" %}
Displays the order book for the selected market.

* **Bid side** (green): Buy orders at various price levels
* **Ask side** (red): Sell orders at various price levels
* **Spread**: The gap between best bid and best ask
* **Midpoint**: Center of the spread, used as reference price

The depth visualization shows cumulative order volume at each price level. Thicker bars indicate more liquidity.

{% hint style="warning" %}
**Taker Cost Warning**: When the spread is wide, a warning appears showing the estimated cost of market-taking (immediate execution). Based on Becker (2025) methodology. See [Taker Cost](file:///6948179/models/taker-cost.md).
{% endhint %}
{% endtab %}

{% tab title="Chart" %}
Price history for the selected market.

* **Timeframe toggles**: 1H, 6H, 1D, 7D, 30D, ALL
* **Price line**: Historical YES price over time
* **Volume bars**: Trading volume per period (when available)

The chart updates in real-time as new trades occur.
{% endtab %}

{% tab title="Models" %}
Quantitative analysis output. This is the analytical core of the terminal.

| Model                     | What It Shows                                      |
| ------------------------- | -------------------------------------------------- |
| **Composite Probability** | Fair value estimate from 11 independent signals    |
| **Bias Zone**             | Whether the market shows longshot or favorite bias |
| **Kelly Criterion**       | Position sizing (Full, Half, Quarter, Empirical)   |
| **Monte Carlo**           | Simulated outcome distribution                     |
| **Expected Value**        | EV, ROI, and breakeven price                       |
| **Implied Theta**         | Time decay rate                                    |

Each model is documented in detail in the [Models](file:///6948179/models/composite-probability.md) section.
{% endtab %}

{% tab title="3D" %}
Three-dimensional wave surface visualization of the order book.

* **X-axis**: Price levels
* **Y-axis**: Time
* **Z-axis (height)**: Order volume
* **Color**: Maps to volume intensity (cool to warm)

The surface updates in real-time. You can rotate, zoom, and pan. See [3D Visualizer](file:///6948179/methodology/3d-visualizer.md) for details.
{% endtab %}

{% tab title="Calibrate" %}
Adjust the parameters that drive all quantitative models. Three presets (Conservative, Balanced, Aggressive) or manual control over every parameter.

Changes apply immediately to all model outputs. See [Calibration](file:///6948179/calibration/presets.md) for the full guide.
{% endtab %}
{% endtabs %}
