  Master real-time execution and liquidity shifts with the Depth of Market (DOM)

The **Order Book DOM** (Depth of Market) is a high-performance execution and analysis tool that provides a vertical representation of market liquidity and real-time transaction flow. It combines limit order depth (**passive liquidity**) with executed trade flow (**aggressive volume**) to help you identify where the market is most likely to find support or resistance.

{% hint style="info" %}
**Single Asset View**: Each Order Book DOM widget is designed to monitor a single coin at a time. To track multiple assets simultaneously, you can add multiple Order Book widgets to your workspace layout.

## Core Functionality

Navigate market depth with precision using professional-grade controls.

- **Symbol Management**:
  - **Switch Symbols**: Click the symbol name to manually search and switch to a different asset.
  - **Multi-Symbol Navigation**: While each widget displays one coin, the search interface allows you to quickly pivot between up to **5 recently selected symbols**.
  - **Sync State**: Toggle the **Link icon** to sync the DOM with your main chart. When enabled, switching your chart's asset will instantly update the DOM widget to match.
- **Depth Exploration**:
  - **Deep Inspection**: Scroll up or down to view bid and ask levels far from the current market price.
  - **Center View**: Use the **Center** button to instantly snap the view back to the mid-price row, which highlights the current **best bid price**.

## Column Breakdown

The DOM is organized into 6 specialized columns to provide total transparency into the auction process:

| Column | Name      | Description                                                                                                                             |
| :----- | :-------- | :-------------------------------------------------------------------------------------------------------------------------------------- |
| **1**  | **Bids**  | Shows **limit order sizes** for buy orders. Uses a color-coded heatmap where bar intensity reflects size relative to the maximum depth. |
| **2**  | **Buys**  | Cumulative counter of **market buy trades** (aggressive takers). Features a green background bar (20% opacity) extending left-to-right. |
| **3**  | **Price** | The central axis. Decimal precision automatically adjusts based on your selected block size/grouping.                                   |
| **4**  | **Sells** | Cumulative counter of **market sell trades**. Features a red background bar (20% opacity) extending right-to-left.                      |
| **5**  | **Asks**  | Shows **limit order sizes** for sell orders. Like the Bids column, it uses heatmap intensity to visualize liquidity depth.              |
| **6**  | **Delta** | The **net difference** between buy and sell volumes shown as a percentage: `(Buys - Sells) / (Buys + Sells) * 100%`.                    |

## Data & Display Customization

### Units & Grouping

- **Unit Toggling**: Switch between **Base Units** (e.g., BTC) or **Total Dollar Value** (USD) to analyze liquidity in your preferred context.
- **Dynamic Price Grouping**: Adjust price precision to compress the book. Available grouping increments are **dynamic** and depend on the specific coin's price.

### Themes & Sensitivity

- **Themes**: Choose from visual presets (e.g., **Sunset**, **Ocean**) to customize the color-coding of the heatmap and trade flow.
- **Sensitivity**: Adjust the sensitivity slider to change the intensity of the heatmap highlights, making significant "liquidity walls" stand out more clearly.

{% hint style="success" %}
The **Buys** and **Sells** columns are cumulative and persist throughout your widget session. Use the **Delta** column to quickly spot imbalances; a high positive delta suggests aggressive buying pressure is absorbing the available ask liquidity.
