# Order Book Profile

> The Order Book Profile overlay: the live order book drawn beside price, its settings, the Heatmap Colors toggle, and the venues it is available on.

The **Order Book Profile** draws the live order book beside the price as a horizontal profile, so you can read the size resting at each level without opening a separate widget. Like the [Liquidity Heatmap](https://takeprofit.com/docs/guide/platform/chart-widget/chart-types/Liquidity-heatmap.md) it is an overlay rather than a chart type, so it sits on top of whatever the chart is already drawing — with the same exception: it is not available on a [Renko](https://takeprofit.com/docs/guide/platform/chart-widget/chart-types/Renko.md) chart.

Use the Order Book Profile to read the book beside price while you watch the chart. Use the [Market Depth widget](https://takeprofit.com/docs/guide/platform/orderbook-widget/market-depth-overview.md) when you want the full price ladder, the Flow view, or to trade straight from the book.

## How to read it

Each row of the profile is one price level of the live order book, and the length of its bar is the size resting there right now.

* **Below the current price** the rows are bids — limit orders waiting to buy. **Above it** they are asks, waiting to sell.
* **A long bar** is a large resting order: a level the market has to absorb before price moves through it.
* **A gap or a run of short bars** is thin book, where price can travel quickly.
* The profile shows what is **resting**, not what has traded. For traded volume at each price, use [Volume Footprint](https://takeprofit.com/docs/guide/platform/chart-widget/chart-types/Volume-Footprint.md).

It is available on **every Bybit and Binance pair, spot and derivatives alike** — a wider set than the heatmap's [supported instruments](https://takeprofit.com/docs/guide/platform/chart-widget/chart-types/Liquidity-heatmap.md#supported-instruments), because it reads the live book instead of replaying stored history. On venues with no order-book feed, **Pepperstone** and **Exness**, the control does not appear at all.

## Settings

Click the **gear** on the on-chart **Order Book** control and the **Order Book Profile** panel opens. `Esc` closes it, and **Reset to Default** at the bottom returns every row to its default.

| Setting | What it does |
| - | - |
| **Row Size** | The price height of one row. **Auto** picks a step suited to the instrument. |
| **Opacity** | How strongly the profile is drawn over the chart, as a percentage. |
| **Width** | How far the profile extends across the chart, as a percentage. |
| **Align** | Which side of the profile the rows are anchored to. |
| **Values** | The per-row size labels, shown or hidden with the **eye**. |
| **Heatmap Colors** | Makes the profile take its colors from the Liquidity Heatmap, so the two overlays match. This row appears only while a heatmap is on the chart. Turn it off to use your own colors below. |
| **Colors** | Four swatches — the bid pair and the ask pair. The arrow resets them to the defaults. |
| **Cumulative Depth** | Draws each row as the running total of size up to that level, rather than the size resting at that level alone. |
