Developing a complete crypto exchange website is a complex task that involves multiple components, including frontend development, backend development, security considerations, user authentication, trading engine, order book management, and more. Below is a simplified example of a crypto exchange website using HTML, CSS, and JavaScript for the frontend.

Please note that this is a basic example for educational purposes. In a real-world scenario, you would need to consider security measures, proper backend architecture, database management, API integrations with cryptocurrency exchanges, and more.

1. **HTML (index.html):**

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Crypto Exchange</title>`
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <header>
        <h1>Crypto Exchange</h1>
    </header>
    <main>
        <section id="ticker">
            <h2>Market Ticker</h2>
            <table>
                <thead>
                    <tr>
                        <th>Currency Pair</th>
                        <th>Last Price</th>
                        <th>24h Change</th>
                    </tr>
                </thead>
                <tbody id="tickerBody">
                    <!-- Ticker data will be populated here using JavaScript -->
                </tbody>
            </table>
        </section>
        <section id="trading">
            <h2>Trade</h2>
            <!-- Trading interface will be built here -->
        </section>
    </main>
    <footer>
        <p>&copy; 2023 Crypto Exchange</p>
    </footer>
    <script src="scripts.js"></script>
</body>
</html>
```

2. **CSS (styles.css):**

```css
body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
    background-color: #f4f4f4;
}

header {
    background-color: #333;
    color: #fff;
    text-align: center;
    padding: 10px;
}

main {
    max-width: 960px;
    margin: 20px auto;
    padding: 20px;
    background-color: #fff;
    border-radius: 5px;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.1);
}

table {
    width: 100%;
    border-collapse: collapse;
    margin-top: 10px;
}

table th, table td {
    padding: 8px;
    border-bottom: 1px solid #ddd;
    text-align: left;
}

footer {
    text-align: center;
    padding: 10px;
    background-color: #333;
    color: #fff;
    position: absolute;
    bottom: 0;
    width: 100%;
}
```

3. **JavaScript (scripts.js):**

```javascript
// Sample data for the ticker
const tickerData = [
    { pair: 'BTC/USD', lastPrice: 45000, change: '+2.5%' },
    { pair: 'ETH/USD', lastPrice: 3200, change: '-1.8%' },
    // Add more ticker data here
];

// Function to populate the ticker table
function populateTicker() {
    const tickerBody = document.getElementById('tickerBody');
    tickerData.forEach(item => {
        const row = document.createElement('tr');
        row.innerHTML = `
            <td>${item.pair}</td>
            <td>${item.lastPrice}</td>
            <td>${item.change}</td>
        `;
        tickerBody.appendChild(row);
    });
}

// Call the function to populate the ticker table
populateTicker();
```

Remember, this is just a basic example to give you an idea of how the frontend of a crypto exchange website might be structured. In a real-world scenario, you would need to integrate this frontend with a backend that handles user authentication, order processing, security, and interacts with cryptocurrency exchanges via APIs. Additionally, security should be a top priority when dealing with financial transactions and user data. Always consult with experienced developers and security experts when building a production-ready crypto exchange website.
