Introduction to Focus Order Issues in Investment Apps

Focus order issues in investment apps can lead to a poor user experience, resulting in frustrated users, negative store ratings, and ultimately, revenue loss. To address this problem, it's essential to understand the technical root causes of focus order issues.

Technical Root Causes of Focus Order Issues

Focus order issues in investment apps are often caused by incorrect or missing tabindex attributes, inadequate keyboard navigation, or poorly structured HTML elements. When developers don't explicitly define the focus order, the browser may assign a default order that doesn't match the visual layout of the app, leading to confusion for users who rely on keyboard navigation or screen readers.

Real-World Impact of Focus Order Issues

Investment apps with focus order issues can lead to user complaints, such as inability to navigate the app using a keyboard or screen reader, and frustration when trying to complete critical tasks like buying or selling stocks. Negative store ratings and revenue loss can result from a poor user experience. For example, a user may not be able to:

• Log in to their account due to focus order issues in the login form
• Navigate to the portfolio overview page due to incorrect keyboard navigation
• Complete a trade due to inaccessible buttons or fields

Examples of Focus Order Issues in Investment Apps

The following are specific examples of how focus order issues can manifest in investment apps:

• Login form issues: The focus order skips the username field and goes directly to the password field, or the "Remember me" checkbox is not accessible via keyboard navigation.
• Navigation menu issues: The navigation menu is not accessible via keyboard navigation, or the focus order is incorrect, causing the user to navigate to an unintended page.
• Stock search issues: The search field is not focusable, or the search results are not accessible via keyboard navigation, making it difficult for users to find and select stocks.
• Portfolio overview issues: The portfolio overview page has incorrect focus order, causing the user to navigate to an unintended section, such as the news feed instead of the portfolio summary.
• Trade execution issues: The trade execution form has inaccessible fields or buttons, or the focus order is incorrect, causing the user to submit an incorrect trade.
• Charting issues: The charting tools are not accessible via keyboard navigation, or the focus order is incorrect, causing the user to navigate to an unintended chart or timeframe.
• Alerts and notifications issues: The alerts and notifications are not accessible via keyboard navigation, or the focus order is incorrect, causing the user to miss critical notifications.

Detecting Focus Order Issues

To detect focus order issues, developers can use tools like:

• WCAG 2.1 AA accessibility guidelines: Check the app's compliance with the Web Content Accessibility Guidelines (WCAG 2.1 AA) to identify potential focus order issues.
• Screen readers: Test the app using screen readers like JAWS or NVDA to identify accessibility issues, including focus order problems.
• Keyboard navigation testing: Test the app using only keyboard navigation to identify focus order issues and inaccessible elements.
• Automated testing tools: Use automated testing tools like SUSA (SUSATest) to identify focus order issues and generate regression test scripts.

Fixing Focus Order Issues

To fix focus order issues, developers can:

• Add tabindex attributes: Explicitly define the focus order using tabindex attributes to ensure that the focus order matches the visual layout of the app.
• Use semantic HTML: Use semantic HTML elements like header, nav, main, section, article, aside, and footer to provide a clear structure to the app.
• Implement keyboard navigation: Implement keyboard navigation to enable users to navigate the app using only their keyboard.
• Test with screen readers: Test the app using screen readers to ensure that it is accessible to users with visual impairments.

For example, to fix the login form issue, developers can add tabindex attributes to the username and password fields, like this:

<form>
  <label for="username">Username:</label>
  <input type="text" id="username" tabindex="1">
  <label for="password">Password:</label>
  <input type="password" id="password" tabindex="2">
  <input type="checkbox" id="remember-me" tabindex="3">
  <label for="remember-me">Remember me</label>
  <button type="submit" tabindex="4">Login</button>
</form>

Preventing Focus Order Issues

To prevent focus order issues, developers can:

• Follow accessibility guidelines: Follow the WCAG 2.1 AA accessibility guidelines to ensure that the app is accessible to users with disabilities.
• Test with screen readers: Test the app using screen readers to identify accessibility issues, including focus order problems.
• Implement automated testing: Implement automated testing using tools like SUSA (SUSATest) to identify focus order issues and generate regression test scripts.
• Conduct regular accessibility audits: Conduct regular accessibility audits to identify and fix focus order issues before they affect users.

By following these best practices, developers can ensure that their investment apps are accessible to all users, including those with disabilities, and provide a positive user experience.
