Depending on personal preference, customers can change the appearance of the background on their OptionsHouse option chain from light to dark (and vice versa).

First, click on the Manage Accounts button at the bottom right-hand corner of the platform.

Make sure the Preferences tab is selected, and click on Display in the secondary navigation menu. Select “Day” (light mode) or “Night” (dark mode) from the drop-down menu next to “Theme.”  From this screen you can also alter your font, if desired, by using the Zoom Factor drop-down menu. You can also choose whether you want these changes to impact one account or all accounts (by clicking on the “Apply to all accounts” checkbox). When finished making your changes, click the Save and Close button.

The background appearance of the trading platform will change accordingly.

Here’s a quick video showing how you can enable white mode and change the font size in your own account(s):
