What is an Order Book?
An order book is an electronic list of buy and sell orders for a particular asset, sorted by price. It provides information about market depth, liquidity, and order size at different price levels. When you place an order to buy or sell a cryptocurrency, it is placed in the order book along with all other pending orders. The order book is updated in real time as new orders are placed, completed, or canceled.
On a spot exchange, the order book typically displays the following information:
Buy Orders: A list of all buy orders containing information about the buyer, the amount the buyer wants to buy, sorted by bid price from highest to lowest.
Sell Orders: A list of all sell orders containing information about the seller, the amount the seller wants to sell, sorted by ask price from lowest to highest.
Bid Price: The highest price a buyer is willing to pay for a particular cryptocurrency.
Ask Price: The lowest price a seller is willing to accept for a particular cryptocurrency.
Spread: The difference between the highest bid and the lowest ask.
Price Chart: A chart showing recent prices, customizable over time frames from one minute to one day.
Depth Chart: A visual representation of the order book - this chart depicts the number of open orders over a price range.
How to Read the Order Book
Reading the order book can be confusing at first, but it's actually quite simple once you get the hang of it. Let's look at an example order book for Bitcoin (BTC) on a spot exchange:
Buy Order:
Price Quantity
$50,000 0.5 BTC
$49,900 1.0 BTC
$49,800 0.5 BTC
$49,700 2.0 BTC
Sell Order:
Price Quantity
$50,100 1.0 BTC
$50,200 0.5 BTC
$50,300 1.0 BTC
$50,400 2.0 BTC
In this example, the bid price is $49,700 and the ask price is $50,100. The spread is $400, representing the difference between the highest buy order and the lowest sell order. The order book shows that there are currently more sellers than buyers because there are more sell orders listed than buy orders.
If you want to buy Bitcoin, you can place an order at a price that matches one of your existing buy orders or place a new buy order at a higher price. If you want to sell Bitcoin, you can place an order at a price that matches one of your existing sell orders or place a new sell order at a lower price.
Why is the order book important?
