Market Depth

The Market Depth widget (also called Order Book) is a live order book you can trade from directly. It shows where buy and sell liquidity is resting for a crypto instrument — and the level you are reading is the level you can place an order at, without retyping a price into a form. You can:

• Trade the ladder itself — place at a price row, drag an order to a new level, cancel it where it rests.
• Read resting buy and sell liquidity, and bid and ask pressure near the spread.
• Spot liquidity walls and thin zones.
• Follow executed trades and short-term order flow in Flow mode.

Trading from the Order Book

Two ways in, depending on whether you want a form in front of you or not.

Sending a level to Order Entry

Click any bid or ask row to open Order Entry pre-filled at that price level — a level you spotted in the ladder becomes an order without retyping the price. The form opens as a preview: nothing reaches the exchange until you review and confirm it, and while it is open the level stays in sync with the chart, the same way chart trading works.

Trading in the ladder

Switch on Trade and the widget becomes an order ladder: you place at a price row without opening a form, and your orders and position appear beside the prices they sit at. A compact panel appears with the three things an order needs:

• The account. One row per connected account, split by Spot and Futures where the venue has both, so you can see which one an order will go to before you place it.
• Quantity. The size every button on the ladder will use.
• Leverage, where the account and instrument support it.

Set the quantity first. The ladder places immediately at the price you click, so an empty quantity field is the one thing that will stop it.

Placing an order

Hover any bid or ask row and an add-order button appears across it. Click it and the order goes in at that row’s price — below the market on the bid side, above it on the ask side. For the market itself, three buttons in the panel cover the common cases:

Your orders in the ladder

A working order shows as a badge on the price it is waiting at. Limit orders and trigger orders are drawn differently, so a stop sitting under your position does not read as another entry.

• Cancel from the × on the badge.
• Drag a badge to another row to move the order to that price — the same gesture as dragging a level on the chart, and the fastest way to follow a level that has moved.
• An order resting away from the current price keeps its badge pinned to the top or bottom edge of the ladder, so you never lose track of one that has scrolled out of view.
• Cancel All and Flatten reach these orders too — see Order Entry.

Your position against the book

An open position is marked on the price scale at its average entry, so you can read it against the liquidity above and below it. Its Take Profit and Stop Loss levels appear in the ladder as their own labels, and a level still pending is drawn differently from one the venue has accepted.

When the ladder stays read-only

Trading switches itself off, and the panel disappears, when there is nothing to trade: an instrument that is not tradable on TakeProfit, or a selected account that cannot trade it — the wrong market, or a key without trading permission. The book keeps working as a market-reading tool either way. For the second case, pick another account in the selector, or see Brokers & Exchanges for what each venue allows.

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

The available elements depend on the selected mode: Depth or Flow.

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:

1. Click the ticker icon in the top-left corner of the widget
2. Select the crypto market you want to open
3. 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)

This mode is designed for analyzing:

• where liquidity is currently placed
• support and resistance formed by order walls
• overall market structure based on resting orders

Use Depth mode when you want a clear snapshot of supply and demand in the book, without execution noise.

---

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)

This allows you to analyze:

• 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
• 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: x10 aggregates 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

This lets you control how detailed the ladder is:

• smaller step → more detailed price levels
• larger step → more aggregated view with less noise

Use a smaller step for precise short-term reading.
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

Keep in mind that the book is dynamic. Orders can appear, shift, or disappear quickly.

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

This can help confirm whether visible liquidity is being respected, absorbed, or aggressively traded through.

Fine-Tune Entry Timing

Use the order book to improve execution around key price levels, especially in fast intraday conditions.
