What is the Order Book

All orders in the market of a trading pair are displayed in a stack of orders known as the Order Book. The Order Book shows all Bids and Offers ranked in order of price.

The orders are stacked with the best price (Best Bid and Best Offer) at the top and each subsequent layer is characterized by a worse price below.

The volume of orders at each price level is also shown through the volume Total on each price level.

In this snapshot of the BTC/USD Order Book the Bid side shows:

• The best Bid (best price you can sell at) is $55,239.90 with an amount of 0.04 BTC available;
• The next best price is 55,239.22 with an amount of 0.04 BTC available;
• The total amount available at both these prices is shown as 0.09 BTC (rounded);
• And so on until the worst price in the book which is $12,500 with an amount of 0.0 BTC (rounded);
• The total aggregated amount available from the best bid to the worst bid is shown in the total column as 0.23 BTC.

• For Limit orders and Stop Limit orders, the Limit price can be quickly populated by mouse-clicking on any price in the orderbook;
• The -/+ signs above the order book can be used to increase or decrease the price range of each layer thereby increasing or decreasing the amount available within the layers in the book;
• A resting order (Limit and Stop) submitted below the best price will sit in the book until executed and will be highlighted in the order book for easy visualization.
