The **Order Book Delta** widget provides a specialized view of liquidity dynamics by tracking the net changes in limit orders over a specific period. Unlike a static Order Book, Delta highlights the "intent" of market participants by showing whether limit orders are being **added** (increasing liquidity) or **subtracted** (removing liquidity) at specific price levels.

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

## Core Functionality

Control how you monitor liquidity shifts with professional-grade navigation and synchronization tools.

- **Symbol Management**:
  - **Switch Symbols**: Click the symbol name to manually search and switch to a different asset.
  - **Multi-Symbol Navigation**: Quickly pivot between your **5 recently selected symbols** within the search interface.
  - **Sync State**: Toggle the **Link icon** to sync the widget with your main chart. When enabled, changing your chart's asset instantly updates the Delta view.
- **Depth Exploration**:
  - **Deep Inspection**: Scroll up or down to view liquidity changes at price levels far from the current market price.
  - **Center View**: Quickly snap the view back to the current mid-price using the **Center** button.

## Advanced Data Analysis

Customize the Delta feed to isolate high-signal liquidity movements.

### Units & Timeframes

- **Unit Toggling**: Switch between **Base Units** (e.g., BTC) or **Total Dollar Value** (USD) to see the scale of liquidity changes in your preferred context.
- **Time Window Selection**: Select different lookback periods—such as **1 Hour, 4 Hours, 12 Hours, or 1 Day**—to analyze liquidity shifts over various trading sessions.

### Grouping & Levels

- **Dynamic Price Grouping**: Adjust price precision to compress the book and identify significant liquidity clusters. Available grouping increments are **dynamic** and depend on the specific coin's price.
- **Historical Breakdown**: Click on any specific price level to view a detailed **histogram breakdown**. This shows exactly when orders were added or subtracted across the selected time window, helping you distinguish between sustained interest and temporary spoofing.

## Color Coding

The widget uses clear visual indicators to represent the direction of liquidity flow:

- **Green Bars (+)**: Indicate liquidity being **added** to the book at that price level.
- **Red Bars (-)**: Indicate liquidity being **subtracted** or canceled from the book.

{% hint style="success" %}
A large green delta bar signifies that liquidity is being added. It acts as a **Buy Wall** if the price level is below the current market price, or a **Sell Wall** if it is above. Conversely, large red bars indicate orders being pulled, which can signal traders repositioning or removing liquidity ahead of volatile moves.
