What Are Crypto Order Books, and How Do They Work?
Reading Time: 4 minutesCan you learn anything about the market conditions from a crypto order book?
An order book provides data for cryptocurrency trading analysis. With it, you can spot important information that can improve your trading decisions. For example, through the order book, you can understand market trends, areas of supply and demand, and good entry positions, among others, by seeing what other traders are doing.
What Is an Order Book?
An order book lists buy and sell orders investors have made for a crypto asset on a centralized exchange. The numbers table contains information about buyer and seller orders, the prices at which they were executed, and the total amounts involved. It is constantly updated throughout the day so that you can get real-time information useful for active trading decision-making.
You can think of it as a behind-the-scenes picture of market demand and supply activities that can be used to identify support and resistance, order balance or imbalance, and other activities that you can exploit.
How Does an Order Book Work?
Every time a limit order is placed, it appears in the order book until it gets executed. The order book lists the amount traders are willing to pay for buy and sell orders, the amount, which is the quantity they want to trade, and the total amount involved.
The order book has a buy and a sell side, revealing the needed information. Seller orders are usually in red, while buyer orders are in green. In some order books, the terms ‘Bid’ and ‘Ask’ are used instead of ‘Buy’ and ‘Sell.’ The buyers are the ones who bid, while the sellers ask for a specific price to sell their positions.
Market Depth Chart
The order book also comes with a visual representation in the form of a line chart to better represent market information. The market depth chart visualizes the supply and demand for a cryptocurrency at different prices and in real time. It shows the weight of buy and sell limit orders in an order book. Just like the order book, it also has a buy side and a sell side.
The horizontal axis of the market depth chart shows the prices at which buy and sell orders are placed, while the vertical axis shows the number of orders placed at each price level. You can hover around the depth chart to see how many buy and sell orders are placed at a specific price.
The market depth chart makes it easy to detect buy and sell walls. A buy wall is formed by large buy orders at a particular price, while large sell orders form the sell walls. The chart’s middle point contains the cryptocurrency’s current market price and the market spread, that is, the difference between the highest bid and lowest ask price.
The term ‘market depth’ refers to a market’s ability to sustain large orders without moving the price significantly. The more buy and sell pending orders placed, the greater the depth of the order book. If the green side is higher than the red, there are more buying interests below the current market price, while a higher red shows more selling interest.
A large buy wall shows that traders believe the price will not likely fall below the specific price level. A large order volume may be enough to drive the price upward if the trades get executed. When sellers see buy walls, they typically exit their positions as the price draws closer to the buy wall, increasing the chances of the trade reversing. The opposite of this is true for the sell walls. The sellers do not believe that the price will rise above a certain level, and they try to push the price back.
How Order Books Are Used in Trading
If the order book or market depth chart shows more buyers than sellers, it could be that a bullish trend is about to start, and the price could start to move upward. Conversely, having more sellers could mean that a downtrend is imminent.
If a specific price level has a lot of buyers, such a price level is usually seen as a strong support level. On the other hand, if there are more sellers at a particular price, it is known as a price resistance level. Combining this with price action and whatever indicators you use could help you make more informed decisions.
How Reliable Is an Order Book in Trading?
The order book is only as reliable as your ability to interpret and incorporate the information it provides into your strategy. It may take some time and practice to understand how it works fully.
Order books can help you know a crypto asset’s supply and demand pressures, with which you can determine if the market is bullish or bearish. The book shows you buying and selling orders at different prices and volumes, and you can use that to know if a token price will move higher or lower in the short term. Traders can also use the information in an order book to determine the best price to buy an asset.
Limitations of Order Books
Crypto market manipulators can deceive traders by providing false clues in the order book. These clues can affect market sentiment and cause traders to make poor decisions. The possibility of manipulation is one reason expert traders don’t treat the order book as the best choice for determining their trading decisions.
There are some trading details hidden from the order book. Thus, we can say that it does not provide full transparency. Consider the trades carried out in a dark pool. These trades are very large and can affect the market’s direction. As a result, they are better negotiated privately. The trade information is only available after the transaction has taken place. With this, one can conclude that the order book is not an exact representation of market demand and supply.
Order book trends change very fast, especially in markets with large trading volumes. As such, long-term traders may not find it useful.
Lastly, the order book trade matching method may not be the best for illiquid markets because it is difficult to find matching orders. As a result, traders may have to wait a long time to get orders executed, and when they are, it could be at an unfavorable price because of large spreads. A decentralized matching engine works better because it fills orders without depending on external liquidity.
Practice Before Incorporating Trading Books Into Your Strategy
Knowing how to read and interpret an order book’s information can help you understand the short-term happenings and trends in a crypto market. However, reading and correctly interpreting the information in the book requires patience and practice.
