# Working space and interface

### Working space

The main component of the interface is the workspace, where the main elements of the terminal are indicated as follows:

* Order Book[ (DOM)](/1ex-smart-dom/features/order-book-dom.md)
* Modules of the Order Book
* Ticker Tape[ (Time\&Sales)](/1ex-smart-dom/features/ticker-tape-time-and-sales.md)
* Clusters
* Candle Charts

Each element is located on a separate tab, has its own settings and a separate trading block. It is possible to open each element independently of each other, so you can assemble a workspace only from the elements you need.

&#x20; Tabs can be moved both vertically and horizontally.

#### Sawing working space

Tabs, windows, settings, and connections are saved automatically when you close the terminal.

### Widgets and side panel

* Each trading element has several widgets:&#x20;
* Settings - each trading element has a number of individual settings.&#x20;
* Working volume - allows you to select a working volume in the required size. It displays the lot size and leverage size when closed.&#x20;
* When the window opens it shows:
  * Balance&#x20;
  * Choice of calculation as a percentage of the base or quotation currency&#x20;
  * Lot size&#x20;
  * Minimum available volume&#x20;
  * Maximum available volume for purchase&#x20;
  * Maximum available volume for sale

* A price multiplier is a numerical multiplier that allows you to change the visible range of prices in the Order Book (a close analogy is the scale of a map). For example, with a multiplier of 1, the price step in the order book is equal to the instrument step. And with a multiplier of 10, the price step increases 10 times and allows the user to see an increased price range. It is possible to select a multiplier value from those proposed or add your own in a separate input field.

**Side panel**&#x20;

The side panel is a part of the interface and makes it possible to access the main elements of the Order Book.
