The order book is data provided by the exchange that shows the total amount of limit buy (bid) and sell (ask) orders placed by traders at each price level.
Its value lies in reflecting the actual levels of supply and demand. However, using it effectively in trading comes with certain challenges. In this article, we will discuss how to overcome these challenges and outline key strategies to help you trade more efficiently.

An exchange is a place where buyers meet sellers, and its primary function is to organize this process efficiently.
The order book is a crucial part of this process, no matter what assets are being traded — whether it is futures, cryptocurrencies, or stocks.
In today’s world, this is highly automated. The exchange’s algorithms are responsible for:
Experiment. If you have an account on an exchange, open a less liquid market and place a limit order. You will see the order book’s value at that price level increase by the volume of your order. Cancel the limit order, and the value will decrease.
This shows that your orders are successfully reaching the exchange and helps you understand how trading works. If the market price hits your limit order, it will be executed as part of a trade.

It depends on the exchange and the application interface. For instance, on the classic BinanceFutures, the order book is displayed on the right side of the screenshot (1):
On the left side of the screenshot, you can see how the order book is displayed on the ATAS platform.
To access this interface: download, install, and launch ATAS > open a chart by selecting an instrument. By default, the Depth of Market (2) indicator is applied to the chart, which directly displays order book data. The visualization is clear: the larger the bar (red or green), the greater the volume of orders at that level.
If needed, you can customize the indicator by opening the indicator manager (Ctrl+I) > selecting Depth of Market and adjusting the settings, such as colors, cumulative values, and other parameters. You can also merge several levels into one using the Scale function from the menu (3).

The order book is characterized by extremely dynamic updates as traders’ orders are placed in large volumes every second:
✔ makes the market more transparent and easier to understand in terms of price movement;
✔ identifies potential support and resistance levels, which is especially useful for intraday traders;
✔ can serve as an additional source of information for developing trading systems, helping to gain a competitive edge;
✔ works well in combination with other volume analysis tools, such as footprint charts.
✘ requires a connection to the exchange (often through a quality data provider), which can add complexity and costs;
✘ you might end up waiting a long time for the right signal, only for the opportunity to act to be very brief;
✘ not ideal for long-term strategies;
✘ difficult to interpret. The fast-paced changes in the order book can be hard to analyze without proper context.
For a more effective analysis of how prices interact with major levels in the order book, it is recommended to use the DOM Levels indicator, which records order book changes over time on the chart.
Simply put, you can view the order book’s history.
The screenshot above shows how you can use DOM Levels to track the movement of significant levels over time. For instance, around the 63,800 mark, the order book displays two levels (green lines below the price) with large bid volumes, but only the upper level (precisely at 63,800) remains constant for several hours.
Note. The DOM Levels indicator loads order book history data from ATAS servers. Due to the large volume, this data is not available for all markets. For more details about the indicator, refer to the Knowledge Base.
In theory, if there are a lot of sell orders at a certain level, it will be harder for the price to push through that resistance. The opposite is true for the support.
In practice, though, the way the price interacts with major levels in the order book can be more complex.
Example. Let’s have a look at the Bitcoin price chart (data from the BitcoinFutures exchange) with the DOM Levels indicator added. The Delta indicator helps you interpret the order book; for instance, when demand absorbs large sell orders, you will see a high green bar on the Delta. The chart also includes the standard Volume indicator.
Bright red levels (1) on the left indicate prices where large sell orders were placed in the order book. This indicates that sellers are active as the price nears the psychological level of $79k, but it does not guarantee that the price will not break through from below. This pattern might suggest that a major player has bearish intentions — using current market demand to gradually close their long positions and/or open shorts ones.
As a result, the price pulls back to point (2). Around the 69,360 level, buy orders start appearing in the order book. These act as support, keeping the price from falling further. The major player might be preventing the price from dropping below this level because they have not fully finished closing their long positions or opening shorts.
In the following hours:
It is important to remember that price patterns and key levels from the order book can vary across different markets. Interpreting large volume levels and the intentions of so-called “smart money” is more like forming hypotheses — they can be accurate or completely wrong. No one can guarantee future price movements.
This strategy involves buying just before significant buy limit orders. The opposite approach is used for selling.
Example. 3-minute chart of BNBUSDT, BinanceFutures data:
This example demonstrates how to use large orders from the order book to identify support and resistance levels for entering long or short positions.
(1) the bright green DOM Levels highlight large orders that have been supporting the price and boosting demand. According to this strategy, you could open long positions near these bright green levels, set a stop-loss just below them, and aim to profit from the upward momentum, which is often short-lived.
(2) the opposite applies for short positions.
Number (3) indicates a long entry signal that did not work out. It became a signal for a breakout trade.
This strategy involves buying when momentum breaks through significant resistance (large sell limit orders at a key level in the order book). The opposite approach is used for selling.
Note that in the previous chart, it is also a support breakout around the $507 level in the upper left corner. After the breakout, this support level became resistance.
Another example. 3-minute Bitcoin price chart with the same set of indicators.
(1) Large sell orders in the order book are exerting pressure on Bitcoin’s price. As time goes on, new sell orders emerge at lower levels, causing a cascading downward movement.
(2) The bright green line indicates a large buy order. It acted as a temporary barrier against the strengthening downtrend.
(3) On this candle, the green line breaks — either the buy orders were absorbed by sellers, or they were canceled under pressure. As a result, the price formed two candles that closed far from the highs (indicating weak bounces) and accelerated its decline.
When the price breaks to new lows under pressure, breakout traders can capitalize on these moments by joining the downward momentum, while protecting their short positions with tight stop-losses.
Alternatively, one might wait for the price to retrace to the breakout level (where the large buy order was in the order book) and enter on what is known as a “breakout test.”
Here is an example (this is an NQ futures chart) that clearly illustrates the concept:
Initially, the 19400 level acted as support (1), as large buy limit orders were placed there in the order book. However, after the breakout, the situation changed — now sell orders are being placed at this level (2), and buyers are hesitant to approach it.
This strategy involves entering a long position after the price breaks through a significant level with large buy orders (a bearish sign), but then recovers and stays above that level (indicating a false breakout).
For selling, the approach is reversed. Let’s look at how this works with the example below.
Example. 3-minute chart of Nasdaq futures.
(1) This is the same 19400 level from the earlier chart. It was broken at the start of the American session (UTC time in the chart). The breakout turned out to be false. Wide price swings are common at the start of a major session, especially if the previous day was volatile. Then buyers renewed their efforts, and the price moved above the 19400 level, which then acted as support.
(2) The price continued to rise to the 19500 level, where sell orders were observed around 14:40. By 15:30, buyers had broken through this level (notice the spike in positive delta).
The price then rose to 19520, where sell orders had previously been spotted in the order book. It was not attacked by the bulls, the price reversed at this resistance and closed on the next candle below 19500 with a negative delta. This resulted in a bearish engulfing candlestick pattern, confirmed by the change in color on the delta indicator and the false breakout of resistance at 19500. This turned out to be the day’s high. Selling on this false bullish breakout at 19500 could have been a very accurate trade, making it a solid example to highlight on social media.
The core idea is that market participants often react to the appearance of large orders in the order book.
For example. When large buy orders appear near the current price in the order book, market participants might react by opening long positions. The opposite is true for short positions.
Number (1) on the chart illustrates this scenario. Limit buy orders just below the current price encouraged traders to go long. However, this might have been a trap set by smart money to find liquidity from buyers and establish short positions.
Soon after, the situation changed: the large buy orders turned red (indicated by arrows 2). These orders put significant pressure on the price, pushing it lower over time until another manipulation occurred.
Number (3) shows sell orders in the book, which prompted traders to sell more (increasing panic). The price did drop, but smart money might have used this as an opportunity to buy back contracts and close (possibly partially) their short positions.
Number (4) indicates genuine signs that buyers became active. However, this did not last long, and with the start of the main session, the downward movement resumed.
When trading based on market manipulation, a trader should monitor situations where sentiment shifts rapidly within a narrow range, and large buy orders are quickly replaced by sell orders. This is likely a sign of manipulation aimed at trapping market participants.

To wrap up the discussion on order book trading strategies, it is important to note that large volumes in the order book often act as support and resistance levels. This gives traders opportunities to use strategies based on price reversals from these levels, breakouts, or false breakouts. However, it is important to keep a few key factors in mind:
In simple terms, it is a compiled list of all active buy and sell orders, organized by price levels.
The order book helps day traders assess supply and demand, spot potential support and resistance levels, and monitor for possible market manipulation.
It can be used to find entry points, develop new trading strategies, and improve the effectiveness of existing approaches. The order book is especially valuable for scalpers and intraday traders.
In most cryptocurrency exchange interfaces, the order information is displayed by default and is labeled as the Order Book. If it is disabled, follow the instructions to enable order display in the settings.
This term refers to the number of levels above and below the current price for which order information is available. In demo versions, providers may limit the depth of data being transmitted.
It is the cumulative information of all buy and sell orders.
On the ATAS platform, this is visualized as a red area (1) extending upward and a green area (2) extending downward, with the total displayed as numbers at the bottom of the indicator. All parameters are customizable.
Trading with the order book is all about developing the skills to interpret and respond to the movements of large volumes in the order book.
