Order Book
A real-time list of outstanding buy and sell orders for a specific trading pair on an exchange. The order book shows the supply and demand for an asset at various price levels. Centralized exchanges use order books; most DEXs use AMMs instead.
Why It Matters
An order book is a list of buy and sell orders for a specific cryptocurrency, displaying the demand and supply in the market. It’s fundamental for traders as it informs decisions about pricing and executing trades.
Example
For instance, if an order book shows many buy orders at a specific price for Ethereum, it indicates a strong demand at that level and may influence new investors' decisions to buy.
Beginner Context
For those new to trading cryptocurrencies, understanding order books is essential. They provide insights into market activity and help traders gauge potential price movements.
