Understanding market dynamics is essential for traders aiming to make informed decisions. One powerful tool that provides real-time insight into supply and demand is Market Depth, commonly known as Depth of Market (DOM). This guide explores what DOM is, how it functions, and how traders can effectively integrate it into their trading strategies to enhance precision and timing.
What Is Depth of Market (DOM)?
Also referred to as the order book, the Depth of Market (DOM) is a real-time display showing the volume of buy and sell orders for a financial asset at various price levels. This visualization helps traders assess market sentiment, liquidity, and potential price movements. A deep market—characterized by numerous pending orders—indicates strong liquidity, which often leads to tighter spreads and smoother trade execution.
DOM acts like a live digital ledger of unexecuted orders, offering transparency beyond the current bid and ask prices. Instead of just seeing the best available price, traders can observe how much buying or selling pressure exists above and below the current market price.

How Does the DOM Work?
Imagine an asset currently trading at $1.00. The DOM will show how many buy orders (bids) exist at $0.90, $0.95, $0.98, and how many sell orders (asks) are placed at $1.02, $1.05, $1.10, and so on. This layered view reveals where support and resistance might form based on actual order concentration.
Because DOM updates in real time, traders can detect sudden shifts—such as large buy walls or aggressive sell-offs—before they significantly impact the price. This makes DOM especially valuable for active traders in fast-moving markets like cryptocurrencies, forex, and futures.
Getting Started with Market Depth
To use DOM effectively, you’ll need access to Level 2 market data, which most advanced brokers provide. Here’s how to begin:
- Open your trading platform and select the asset you want to analyze.
- Click the Trade button in your trading panel.
- On the right side of the screen, switch to the DOM tab (as opposed to the standard Order tab).
- You’ll now see the depth of market for your selected asset.
If no data appears, it may mean that either the symbol isn’t supported by your broker or Level 2 data isn’t available for that instrument.
Key Elements of the DOM Interface
Understanding the components of a DOM interface is crucial for efficient trading:
- Pending Orders: Visible buy (bids) and sell (asks) orders waiting to be executed.
- Bid/Ask Volume: The total quantity of orders at each price level.
- Order Placement Cells: Clickable price levels where you can place limit or stop orders.
- Order Management Buttons: Options to cancel all limit or stop orders on a given instrument.
- Center Button: Quickly re-centers the DOM view around the current market price.
- Position Size Indicator: Shows total open position size.
- P&L Display: Tracks unrealized profit or loss; toggle between monetary value, pips, or percentage.
- Close/Reverse Position Buttons: One-click tools to exit or flip an existing position.
- Cancel All Orders Button: Removes every pending order for the current instrument.
- Quantity Field: Sets how many units you wish to buy or sell.
Data Sources for DOM
DOM data is sourced directly from your broker’s order flow. While this data aligns closely with live market conditions, slight discrepancies may occur between DOM and chart prices due to differences in data feeds or latency.
The DOM presents a static price ladder, meaning the listed price levels remain fixed even as the market price moves. However, traders can use the center button to refocus the ladder on the current price, maintaining relevance during volatile periods.

Placing Orders Using DOM
DOM isn’t just observational—it’s interactive. Here’s how to execute trades directly from the DOM:
- Market Orders: Click “Buy Market” or “Sell Market.” The quantity is set in the Quantity Field.
- Limit Orders: Click on a price cell in the left column (to buy) or right column (to sell).
- Stop Orders: Hold Ctrl (Windows) or Command (Mac) and click a price cell.
- Right-Click Menu: Right-click any price level to access a pop-up with options: market, limit, or stop order.
You can disable confirmation pop-ups in settings for faster execution—a key advantage in high-speed trading environments.
Modifying Active Orders
Adjusting orders is simple:
- Click an existing order in the order book to open a modification window.
- Change parameters such as price or quantity, then click “Modify Order.”
- Alternatively, drag the order to a new price level—this triggers the same edit dialog.
This flexibility allows traders to adapt quickly to changing market conditions without exiting and re-entering positions.
Interpreting DOM Colors and Labels
Visual cues help traders identify order types at a glance:
- Green entries indicate active buy limit or sell limit orders.
- Red entries represent active buy stop or sell stop orders.
- Yellow entries show stop-limit orders, where the limit price is less prominent than the stop level.
These color codes streamline decision-making during fast-paced sessions.
Managing Open Positions
DOM displays your total open position size at the bottom:
- Blue indicates a long (buy) position.
- Red indicates a short (sell) position.
From here, you can:
- Click Flatten [9] to close the position.
- Click Reverse [10] to close the current position and open an opposite one instantly.
This real-time feedback loop enhances risk management and strategic agility.
Canceling Orders
Canceling orders is straightforward:
- Single Order: Click the “X” next to its label.
- All Buy Orders: Click the “X” under the blue bid column.
- All Sell Orders: Click the “X” under the red ask column.
- All Orders: Use the CXL ALL button at the bottom.
This granular control prevents accidental exposure and supports disciplined trading.
Frequently Asked Questions (FAQ)
Q: Is DOM only useful for professional traders?
A: No. While DOM is widely used by professionals, retail traders can also benefit—especially those trading highly liquid assets or using scalping and day trading strategies.
Q: Can DOM predict price movements?
A: Not definitively, but it can highlight areas of strong support/resistance based on order clustering, helping anticipate potential reversals or breakouts.
Q: Do all brokers offer DOM functionality?
A: No. Access depends on whether your broker provides Level 2 data and an advanced trading interface that supports order book visualization.
Q: Is DOM relevant for long-term investors?
A: Less so. DOM is most valuable for short-term traders who need real-time order flow insights. Long-term investors typically rely more on fundamentals and chart patterns.
Q: How does DOM differ from a standard price chart?
A: Charts show historical prices and volume over time. DOM shows real-time pending orders at specific price points—offering a forward-looking view of supply and demand.
Q: Can I use DOM for cryptocurrency trading?
A: Absolutely. Many crypto exchanges offer DOM tools, making it especially useful in volatile digital asset markets.
