You can always choose whether to have Light or Dark charts and interface. Turn on our Dark theme, if you prefer a more relaxed view.
Note: If you're looking for how to switch theme in our Desktop app, refer to the article How do I switch the app to Dark or Light color theme.
To switch between Light and Dark interfaces, move the slider in the pull-down menu of the upper button in the left.
Also, you can switch the color theme through the chart context menu.
Click the chart with the right mouse button, hover over the Color theme item and select the theme you desire.
