How to Read the Binance Depth Chart: What Do the Green and Red Curves Mean?
The depth chart visually displays order book density. Learn how to interpret the green and red curves and identify large orders in just 30 seconds.
The depth chart is far more intuitive than scanning lists of numbers in an order book. First, log in to the Binance Official Website, and use the Binance Official App for mobile (see the iOS installation tutorial for Apple users).
Components of a Depth Chart
You can open the "Depth" view on any Binance trading page. You will see:
- Center Price Line: Represents the current market price.
- Green Curve (Left): Cumulative buy order depth (Bids).
- Red Curve (Right): Cumulative sell order depth (Asks).
- X-axis: Price levels.
- Y-axis: Cumulative quantity of orders.
How to Read It
1. Curve Steepness
The steeper the curve, the more orders are concentrated at those price levels, indicating a "thick" market.
2. Curve "Steps"
A sudden vertical "step" or "cliff" in the curve indicates a massive single order sitting at that specific price.
3. Comparing the Sides
- Green > Red: Buy interest is stronger; price tends to be pushed upward.
- Red > Green: Sell interest is stronger; price tends to be pushed downward.
4. Distance to the Center
The further the curves are from the center price, the higher the slippage. Curves close to the center indicate high liquidity and tight spreads.
Practical Identification
1. Identifying "Whales"
A vertical wall in the depth chart often represents a "Whale" order.
Judgment:
- Stays for long: A real whale or strong institutional interest; the price will struggle to break through.
- Disappears in seconds: A fake order designed to manipulate sentiment (spoofing).
- Repeatedly appears/disappears: Likely an algorithmic bot at work.
2. Liquidity "Black Holes"
If the curve is very flat near a price level, there are almost no orders. If the market hits this area, the price may "flash crash" or "spike" instantly through the gap.
3. Support and Resistance
Areas with a high concentration of buy orders act as Support. Areas with a high concentration of sell orders act as Resistance. You can use the depth chart to verify support/resistance levels from your technical analysis in real-time.
Depth Chart vs. Order Book
The Order Book is a discrete list of numbers. The Depth Chart is a cumulative visualization of those same numbers.

| View overall market "thickness" | Depth Chart |
| Identify large order walls | Depth Chart |
Limitations of Depth Charts
1. No Historical Data
It only shows the current state of the market. It cannot tell you how depth has changed over time.
2. Vulnerable to "Spoofing"
Bots frequently place large orders only to cancel them right before execution to scare retail traders.
3. No Trade Direction
It shows limit orders (resting liquidity), not market orders (actual trades). Use K-line charts and the "Trade History" for completed transactions.
Desktop vs. Mobile
- Desktop: Offers a larger view, is clearer, and allows for zooming and precise price inspection.
- Mobile App: The chart is compressed and is best for a quick, "at-a-glance" overview. Professional traders prefer the desktop version for depth analysis.
Measuring Liquidity Depth
Binance provides market depth indicators based on percentages:
- Cumulative orders within ±0.1% of the market price.
- Cumulative orders within ±1% or ±2%. Mainstream coins typically have millions of USDT in depth within ±0.1%. Altcoins may only have a few thousand. Higher numbers mean a deeper market with less price impact from large trades.
Advanced Depth Analysis
1. Divergence
If the price is rising but the red curve (sell side) is thickening significantly, overhead resistance is growing, suggesting a potential top.
2. Accumulation
If the price is sideways but the green curve (buy side) is steadily thickening, large capital may be accumulating in anticipation of an upward move.
3. Distribution
If large sell walls suddenly appear during an uptrend, it’s a sign that whales are offloading their positions.
Using Depth Charts to Place Orders
Slicing Large Orders
Before making a large buy, check the depth:
- The thickness of the first few ask levels determines how much you can buy without moving the price.
- If the first level is thin, consider splitting your order into smaller batches.
Positioning Limit Orders
Place your orders near "walls" for protection:
- Buying: Place your bid 1-2 ticks above a large buy wall.
- Selling: Place your ask 1-2 ticks below a large sell wall. Use the large orders of others as a "shield" for your price entry or exit.
FAQ
Q: Can the depth chart predict short-term price movements? A: It cannot predict them with 100% certainty, but it provides high-probability hints about where the price might encounter friction.
Q: Why does the depth chart suddenly go blank? A: This is usually due to a WebSocket disconnection. Refresh the page or check your internet connection.
Q: Is it hard to see specific prices on the mobile app? A: Yes, the mobile app compresses the chart. For detailed analysis, use the desktop site or the "full screen" mode on the app if available.
Q: Can I see historical depth? A: No. It only shows the live, resting order book. For history, you must refer to the K-line (candlestick) charts.
Q: Is the depth chart accurate? A: Yes, it is a direct visualization of the live order book. However, remember that the order book itself can contain many non-persistent "fake" orders.
