### Orderbook heatmap

**What it is:** A **color layer** behind the candles showing **where limit orders sat** in the book over time (liquidity), not only trades.

**How to use it**

1. Click the **heatmap** icon in the top bar (fire icon on desktop, or under **More** on mobile) to **turn it on**.
2. When a **slider** appears, drag its ends to **narrow or widen** the size range you care about. That helps hide noise or focus on **large** resting liquidity.
3. **Hover** the chart to read **tooltip** details where supported.
4. Turn the heatmap **off** again with the same button. The slider usually **resets** when you switch it off.

**Tip:** Heatmap needs **depth history** for the symbol; if data is still loading, wait a few seconds or zoom to a shorter visible range.

### Footprint chart

The footprint shows **volume at each price** inside a candle. From the **chart type** menu, choose **Footprint** and then **Bid×Ask**, **Delta**, or **Volume**.

For **how to read** footprint and optional **signal labels**, see the Footprint help center.

***

### Bar replay

**What it is:** Practice or review by **playing back** historical candles **step by step** or **automatically**, without new live bars arriving until you exit.

**How to start**

1. Click the **Bar replay** (play icon) in the top bar or **More** menu.
2. A **control bar** appears (play/pause, speed, timeline, exit).

**Controls**

* **Play/pause** — Run or stop automatic playback.
* **Step** — Move one bar forward or back.
* **Speed** — Faster or slower playback.
* **Timeline** — Jump to another point in history.
* **Exit** — Return to **live** data and normal scrolling.

**Keyboard:** While replay is active (and you are not typing in a box), **Space** plays/pauses, **arrow keys** step, **Esc** exits. Details: Keyboard shortcuts.

***

### Layouts (saved workspaces)

**What it is:** A **layout** remembers a combination of **which indicators are on**, **which side panels are open**, **drawings**, and related options — so you can switch between setups (for example “scalping” vs “swing”) without redoing everything.

**Typical actions**

* **Choose** a saved layout from the layout control in the top bar.
* **Save** the current setup under a name.
* **Rename**, **duplicate**, or **delete** layouts from the same menu.
* Turn **autosave** on if you want the **current** layout updated as you work.

**Shortcut:** **Ctrl+S** (Windows) or **⌘S** (Mac) often **saves the layout** in the terminal — not the same as your browser’s “Save page”.

***

### Screenshots (snapshot)

1. Click the **camera** icon.
2. Choose **Download** to save a **PNG** image, or **Copy** to put it on the clipboard (for pasting into chat or notes).

Shortcuts: **Ctrl+Shift+S** / **⌘⇧S** (download), **Ctrl+Shift+C** / **⌘⇧C** (copy) — see Keyboard shortcuts.

On some phones, **share** may open instead of a file save.

***

### Alerts

The **bell** icon opens **alerts** (where your subscription allows). Unread count may appear on mobile inside the **More** menu.

***

### If you switch browser tabs

The chart may **pause** heavy updates while the tab is in the background and **catch up** when you come back. If something looks out of date, **zoom** slightly or wait for the next tick.

***

**Next:** Phone, tablet & two charts
