- resting buy and sell liquidity
- bid and ask pressure near the spread
- liquidity walls and thin zones
- executed trades and short-term order flow in Flow mode
Market Depth is available for crypto instruments from 70+ supported exchanges.
Widget Structure
The Market Depth widget combines two types of market data:- Depth data — resting bid and ask liquidity in the order book
- Flow data — recent executed trades and trade clusters
Main Elements
-
Price ladder
- The vertical scale with price levels
- Updates in real time as the market moves
-
Bids
- Buy orders, shown in green
- Represent demand below or near the current price
-
Asks
- Sell orders, shown in red
- Represent supply above or near the current price
-
Liquidity bars
- Horizontal bars at each price level
- Show how much volume is resting on bids and asks
-
Volume labels
- Numeric size values displayed directly on the ladder
-
Spread
- The distance between the best bid and best ask
- Represents the nearest executable buy/sell gap
-
Cumulative depth curve
- A stepped line showing how liquidity builds up further away from the spread
- Useful for spotting larger liquidity walls
-
Trade clusters (Flow mode)
- Grouped executed trades displayed inside the widget
- Help show where buying or selling activity is actually taking place
Choosing an Instrument
To change the instrument:- Click the ticker icon in the top-left corner of the widget
- Select the crypto market you want to open
- Choose an available exchange or trading venue
Display Modes
The widget supports two viewing modes:- Depth
- Flow
Depth Mode
Depth mode focuses on the current state of the order book. It provides a clean and structured view of:- Bid and ask ladders
- Price levels
- Liquidity bars
- Volume at each level
- Cumulative depth (optional)
- where liquidity is currently placed
- support and resistance formed by order walls
- overall market structure based on resting orders
Flow Mode
Flow mode adds real-time trade execution data on top of the order book. In addition to standard depth, it displays:- Recent trades (executed orders)
- Aggregated trade prints
- Trade clusters (visualized as candles inside the widget)
- Filters for trade size and activity
What the candles in the center represent
The candles shown in the middle of the widget represent trade flow clusters — grouped executions over a short time interval. They are not standard chart candles. Instead, they show:- where trades were executed relative to the spread
- intensity of buying vs selling activity
- short-term reaction of price to order flow
- Green candles → aggressive buyers (market buys)
- Red candles → aggressive sellers (market sells)
- whether liquidity is being absorbed or respected
- where actual trading activity is concentrated
- how execution flow interacts with visible order book levels
Depth vs Flow — When to Use
-
Use Depth mode when:
- you analyze liquidity structure
- you look for support/resistance from order walls
- you need a clean and stable view
-
Use Flow mode when:
- you want to track real-time executions
- you analyze buyer/seller aggression
- you combine liquidity with trade activity
Depth and Flow Settings
Open Market Depth Settings to switch between modes and adjust the widget behavior. The available settings depend on the selected mode.General
-
Depth / Flow
- Switch between the two display modes:
- Depth — shows resting bid and ask liquidity
- Flow — adds executed trade activity and trade clusters
- Switch between the two display modes:
-
Bid/Ask Ratio (Depth mode)
- Shows the balance between bid and ask liquidity
-
Show Empty Rows (Depth mode)
- Displays price levels even when no orders are currently available at those levels
-
Price Step
- Groups price levels by step multiplier
- Example:
x10aggregates price levels into larger steps for a cleaner view
-
Font Size
- Changes the size of ladder labels and volume values
-
Auto-centered
- Keeps the spread area centered automatically
Volume
-
Volume Bars
- Show or hide horizontal liquidity bars
-
Volume Scale
- Controls how volume bars are scaled
- Example: Linear
-
Cumulative Volume
- Enables the stepped cumulative depth curve
Trades (Flow mode)
-
Display Type
- Changes how executed trades are displayed inside the Flow view
-
Aggregation
- Groups executed trades into larger prints
- Helps reduce noise in fast-moving markets
-
Volume Filter
- Hides executed trades below the selected volume threshold
Clusters (Flow mode)
-
Period
- Defines the time interval used for trade cluster visualization
- Example:
5m
-
Skip Empty Clusters
- Hides cluster intervals without meaningful trade activity
Reset to Default
Use Reset to Default to restore the widget settings to their default configuration.Top-Right Controls
In the top-right corner of the widget, you can find quick controls for depth navigation and price aggregation.Bring Spread Back to the Center
Click the centering icon to bring the spread back to the center. Use it when:- you manually scrolled away from the current price
- the active spread is no longer visible in the middle of the widget
- you want to quickly refocus on the live market
Price Step Control
Next to the centering button, you can adjust the price step directly from the widget header. This control includes:- minus (-) — decrease the step
- current value (for example
0.01) — shows the active price increment - plus (+) — increase the step
- smaller step → more detailed price levels
- larger step → more aggregated view with less noise
Use a larger step when you want a cleaner overview of liquidity distribution.
How to Read Market Depth
Use the Order Book to interpret short-term market structure:- Large bid walls can act as support
- Large ask walls can act as resistance
- Thin liquidity can lead to faster moves
- Imbalance between bids and asks can indicate directional pressure
Practical Use Cases
Identify Liquidity Zones
Look for large concentrations of resting orders. These often define short-term reaction levels.Watch the Spread
A tight spread usually reflects better liquidity. A wider spread may indicate thinner conditions or higher uncertainty.Combine Liquidity and Executions
In Flow mode, compare:- where liquidity is resting
- where trades are actually executing
