Crypto exchange order book screen

A crypto exchange order book screen displays real-time market depth, buy and sell offers, essential for traders.

About this subject

The order book is a central tool in cryptocurrency exchanges like Binance, Coinbase, or Kraken. It lists all open buy (bids) and sell (asks) orders for a trading pair, sorted by price. Market depth, visualized as a step graph, shows available liquidity at each price level. Traders use this data to identify support and resistance, and to detect large orders that may indicate price movements. The screen typically includes the spread (difference between best bid and ask), accumulated volume, and real-time updates via WebSocket. Decentralized exchanges (DEXs) like Uniswap have on-chain order books, but most DEXs use an AMM model, different from the traditional order book. The concept of order books originated in traditional financial markets, like the New York Stock Exchange, and was adapted for crypto. The transparency of the order book is an advantage of cryptocurrencies, allowing anyone to see liquidity and order flow. In Brazil, exchanges like Mercado Bitcoin and Foxbit also offer order books for pairs like BTC/BRL.

Frequently Asked Questions

What is an order book in cryptocurrencies?

It is an electronic list of buy and sell orders for an asset, sorted by price, showing market depth and available liquidity.

How to interpret market depth on an order book?

Depth shows the quantity of orders at each price. A steep step graph indicates low liquidity, while smooth steps indicate high liquidity. Large order walls can act as support or resistance.

What is the difference between an order book on centralized and decentralized exchanges?

Centralized exchanges (CEX) maintain the order book on their own servers, with fast updates. Decentralized exchanges (DEX) typically use AMM models, without a traditional order book, but some DEXs have on-chain order books, which are slower and more expensive.
