# What is an order book?

An order book is a list of buy and sell orders organized by price levels.   
  
An order book consists of a list of trader open orders. The orderbook is split into bids and asks at various prices (price levels). The order book is used to identify market demand and allows traders to see what can be sold and bought at the market.  
  
Placing orders in front of other people's orders (higher when buying or lower when selling) will help guarantee that your order/s are filled.

10 levels are visible by default on the order book. For those who want to have a deeper insight into the order book, they can increase the levels in the settings -> interface.

Happy trading
