Depth of Market (DOM), also called Level 2 data, displays the full order book showing all pending buy bids and sell asks at every price level. It reveals the available liquidity and potential support or resistance zones created by large resting limit orders.
The Depth of Market display shows a real-time ladder of all limit orders waiting to be filled at each price level. The left side shows bids (buy orders) stacked below the current price, and the right side shows asks (sell orders) stacked above it. The size of orders at each level indicates how much liquidity exists there.
DOM provides critical information that candlestick charts cannot show. A large cluster of buy orders at a price level suggests strong support, while a wall of sell orders indicates potential resistance. Traders watch for these walls to be consumed (indicating strong momentum) or pulled (indicating manipulation).
According to a 2021 report by Kaiko Research, the top 5% of orders by size on Binance's BTC/USDT pair accounted for roughly 38% of total order book depth, demonstrating significant concentration of liquidity among large players. This concentration makes DOM analysis particularly valuable in crypto, where whale orders can move markets substantially.
Professional day traders and scalpers use DOM to time entries and exits with precision. By watching the speed at which orders are filled and the pace of new orders appearing, experienced traders can gauge short-term directional bias within seconds. DOM trading requires fast execution, low latency, and significant screen time to develop pattern recognition skills.
Frequently Asked Questions
What is the difference between Level 1 and Level 2 market data?
Level 1 shows only the best bid and best ask (top of book). Level 2 (DOM) shows the full depth of the order book — all pending orders at every price level. Level 2 reveals where large orders are resting and how much liquidity exists at each price, providing far more actionable information.
Can you see whale orders on Depth of Market?
Yes, large limit orders from whales are visible on DOM as unusually thick levels. However, sophisticated traders use iceberg orders (splitting large orders into smaller visible chunks) to hide their true size. DOM shows what is visible, not necessarily the full picture.

Order Book
An order book is a real-time list of all pending buy and sell orders for a trading pair on an exchange, showing the price and quantity of each order awaiting execution. On highly liquid exchanges like Binance, the order book refreshes hundreds of times per second, with Bitcoin typically showing millions of dollars in resting orders.
Order Flow Analysis
Order flow analysis examines real-time buy and sell orders hitting the market to understand supply and demand imbalances. By tracking aggressive market orders against the order book, traders can anticipate short-term price movements before they appear on candlestick charts.
Bid-Ask Spread
The bid-ask spread is the difference between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask), representing the implicit transaction cost of an immediate trade. On major exchanges like Binance, Bitcoin spreads are typically just $1-5, or 0.002-0.01%, while low-cap altcoins can have spreads of 1-5%.
Liquidity Grab
A liquidity grab (also called a stop hunt or liquidity sweep) occurs when price moves beyond a key level to trigger clustered stop-loss orders, then quickly reverses. Smart money uses these events to fill large positions at favorable prices by taking the opposite side of retail stop-loss liquidations.
