Exchanges use order books to display current buy and sell orders. The system displays two types of information, which show traders asset purchase prices and other traders’ asset selling prices. The order book is one of the core tools used to understand market activity and price formation.
The order book is usually divided into two sides. The bid side contains buy orders which represent demand. The ask side contains sell orders which represent supply. Each side lists prices along with the quantity available at each level. The highest bid and the lowest ask are especially important because they define the current spread which measures the distance between buying and selling prices.
All order books maintain constant updates because traders create new orders, change current orders, or complete trades. Market orders link with existing limit orders through order book submission. Buyers and sellers create price movements through their trading activity. Price levels which contain large orders function as short-term support and resistance points but traders can cancel those orders anytime.
A market displays liquid conditions when its order book contains extensive buy and sell orders across various price points. A market with a low order book threshold experiences increased price volatility because even minor transactions can cause major price fluctuations.
