The order book is a fundamental tool in financial markets, including the cryptocurrency market. It is a real-time record of all buy and sell orders that users have placed in a specific market.

This ledger displays the market dynamics by showing the supply and demand for a particular asset. Each entry in the order book includes information about the quantity of assets offered at a specific price (sell orders) and the quantity being sought to purchase at another price (buy orders).

One key feature of the order book is execution priority. Sell orders with lower prices and buy orders with higher prices take priority over others. This means that when a buy order and a sell order match at the same price, the order placed first will be executed first.

By observing the order book, traders can gain valuable insights into the supply and demand in the market at any given time.

Furthermore, the order book can provide hints about potential market trends. For instance, if there are many buy orders at a specific price, it may indicate a support level where traders believe the price is attractive for buying. Conversely, if there are numerous sell orders at a certain price, it may indicate a resistance level where traders expect the price to decrease.

By analyzing the order book, traders can make more informed decisions and gain a better understanding of the real-time market dynamics.
