# Liquidity Levels

<mark style="color:$info;">The Liquidity Mapping feature in the Sonar extension provides a real-time visual representation of resting limit orders across the market. By aggregating order book data from multiple major exchanges, Sonar identifies where the strongest "Liquidity Walls" are located, allowing you to see where price is likely to react.</mark>

<mark style="color:$info;">Liquidity refers to the volume of buy and sell orders waiting to be filled at specific price points.</mark>

* <mark style="color:$info;">Ask Levels (Red): Represent sell walls (resistance).</mark>
* <mark style="color:$info;">Bid Levels (Teal): Represent buy walls (support).</mark>

<mark style="color:$info;">By visualizing these levels directly on your chart, you can identify high-interest zones that traditional candle patterns might miss.</mark>

#### Depth&#x20;

<mark style="color:$info;">The Depth dropdown allows you to control how much of the order book you are viewing:</mark>

* <mark style="color:$info;">Low Depth (e.g., 50): Shows only the orders closest to the current price (useful for scalping).</mark>
* <mark style="color:$info;">High Depth (e.g., 500): Shows massive "Whale Walls" further away from the current price (useful for swing trading and macro targets).</mark>

#### Custom Colors

<mark style="color:$info;">Personalize your interface to match your chart theme:</mark>

* <mark style="color:$info;">Bid Line Color: Customize the color for buy orders (Default: Teal).</mark>
* <mark style="color:$info;">Ask Line Color: Customize the color for sell orders (Default: Coral/Red).</mark>
