Change your Fidelity theme to black in three steps
Open Fidelity on your computer or phone, go to your account settings, and select the dark theme option. The exact location depends on whether you use the website or the mobile app, but both offer a black or dark mode that reduces eye strain and works the same way across all Fidelity pages and tools.
Dark mode is a display preference only — it does not change how your account works, what you can see, or how you trade. Once you turn it on, Fidelity remembers your choice and applies it every time you log in from that device.
Key Takeaways
- On the Fidelity website, go to Settings, then Preferences, then select Dark Theme under Display Options.
- On the Fidelity mobile app, tap the menu icon, select Settings, then choose Dark Mode from the Display section.
- Dark mode applies only to your display and does not affect your account security, holdings, or trading ability.
- Your theme choice is saved to your account and will carry over when you log in on the same device.
- If you use multiple devices, you must turn on dark mode separately on each one — the setting does not sync across phones and computers.
Dark mode on the Fidelity website
Log into your Fidelity account at fidelity.com. In the top right corner, click your name or profile icon, then select Settings from the dropdown menu.
On the Settings page, click Preferences on the left side. Scroll down to the Display Options section and select Dark Theme. The page will refresh immediately and switch to black. Click Save at the bottom of the page to confirm your choice.
After you save, dark mode will apply to your dashboard, research tools, watchlists, and trading screens. The change takes effect right away and will remain active the next time you log in from that same browser.
Dark mode on the Fidelity mobile app
Open the Fidelity app on your phone. Tap the menu icon (three horizontal lines) at the bottom right of the screen, then tap Settings.
Scroll to the Display section and toggle Dark Mode on. The app will switch to black immediately. Your choice is saved automatically — you do not need to confirm it.
The next time you open the Fidelity app on that phone, dark mode will be on by default. If you use the app on a tablet or a different phone, you will need to turn on dark mode there separately.
What dark mode does and does not change
Dark mode changes only the color of the background and text on your screen. Everything else — your account balance, positions, watchlists, trading tools, and security settings — remains exactly the same. You can still see all the same information and perform all the same actions.
Dark mode does not affect your login security, two-factor authentication, or any other account protection. It is purely a visual preference and does not interact with your holdings or trading activity. Your account data, transaction history, and all other information display identically in both light and dark modes.
Dark mode on different devices
Fidelity saves your theme choice separately for each device you use. If you turn on dark mode on your computer, your phone will still show the light theme until you change it there too. If you use multiple computers or phones, you will need to set dark mode on each one individually.
If you clear your browser cache or cookies, your theme preference may reset to the default light mode on that browser. Log back into Settings and select Dark Theme again if this happens. On the mobile app, uninstalling and reinstalling the app may also reset your display preference to light mode.
Troubleshooting dark mode problems
If dark mode is not working or the page looks broken after you turn it on, try logging out and logging back in. Sometimes the display does not refresh properly until you close your session and start fresh.
If the problem continues, clear your browser cache (or reinstall the mobile app) and log in again. If dark mode still does not work, contact Fidelity support — they can check whether your account has any display settings that override your theme choice or whether a technical issue is preventing the setting from saving.
Switching back to light mode
You can turn off dark mode at any time by going back to the same settings location. On the website, go to Settings, then Preferences, then Display Options, and select Light Theme. On the mobile app, go to Settings, then Display, and toggle Dark Mode off.
Your account will switch back to the light theme immediately. All your account information, trades, and settings remain unchanged — only the visual appearance of the screen changes.
Frequently Asked Questions
Does dark mode work on all Fidelity pages?
Dark mode applies to the main Fidelity website and mobile app, including your account dashboard, research tools, and trading screens. Some third-party tools or older pages may not support it, but the core Fidelity experience will be black once you turn it on.
Can I schedule dark mode to turn on automatically at night?
Fidelity does not have a built-in scheduling feature for dark mode. You can turn it on or off manually whenever you want, but you cannot set it to switch automatically at a certain time of day.
Will dark mode slow down my account or affect my trades?
No. Dark mode is only a visual change and has no effect on how fast your account loads, how your trades execute, or any other performance. It is purely a display preference.
What if I turn on dark mode on my computer but want light mode on my phone?
You can use different themes on different devices. Your theme choice is saved separately for each device, so you can have dark mode on your computer and light mode on your phone at the same time.
Will my dark mode setting stay if I log out?
Yes. Your theme choice is saved to your account and will remain active the next time you log in from that device, even if you log out in between.
