How to read an order book: a thread
Order Book refers to a digital list of buy and sell orders on an exchange. Every coin traded on an exchange has a separate order book. All exchanges maintain order books that will have a list of orders placed for assets such as stocks, bonds, and cryptos.
Order books are organised by price level and list the number of coins that could be traded at every price point.
The primary function of every exchange is to match compatible buyers with sellers at every price point, and an order book executes that task.
Buyers post ‘bids’ on the exchange for specific coins while sellers post ‘asks’. Trades on both ends are executed when a match is found. Order books, which are dynamic in nature, keep track of these evolving bids and asks in real time.
A typical order book consists of 3 main components: buy orders, sell orders, and trading history.
Bid vs AskBuy orders include ‘bids,’ which consist of the price and quantity a buyer wishes to purchase. Sell orders include the price at which sellers are willing to let go of their coins and sale amount.
Thus, a bid is the buy price, while an ask is the selling price.
Buy & Sell OrdersBuy orders follow descending order, meaning the highest bid is at the top of the order book. Sell orders are in ascending order, so you will find the lowest sell price at the top.
The trade is executed if the highest buy price matches the lowest sell.
Trading history and other partsBesides ask and bid prices, order books also typically contain order histories that help determine the overall direction of market prices. Some books may also contain market, stop-loss, limit, and trailing-stop orders.
