## 1. Definition

**Spread** is the difference between the Ask price (Buy price) and the Bid price (Sell price) of an instrument at a specific moment.

Spread represents the immediate transaction cost paid by the client when opening a position.

```
Spread = Ask - Bid
```

Where:

- **Ask** — price displayed in the Buy button
- **Bid** — price displayed in the Sell button

## 3. Example

Spread is measured in the **instrument price unit**.

For instruments quoted against USD (e.g. USOUSD, WTI, BRENT, BTCUSD):

```
Unit = USD
```

Example:

```
Ask = 72.68
Bid = 72.36

Spread = 72.68 - 72.36 = 0.32
```

Result: **0.32 USD**
