# Order Book basics

Displays all the live resting orders available on a market

### **What is an Order Book?**

An order book is a list of all the buy and sell orders for a particular market. It lets traders specify the price they’re willing to pay (or accept) and the number of shares they want to trade. This feature is transformational because it offers a structured way to match trades and provides transparency into market depth

* <mark style="color:red;">Sell</mark> orders are standing offers to sell shares. You can immediately match with that offer to purchase shares.&#x20;
* <mark style="color:green;">Buy</mark> orders are standing offers to buy shares. You can provide your own "resting" offer to buy at the same price.
* **Spread** is the difference between the highest Sell and the lowest Buy price.
