Overall Excellent... With One Nuisance – TD Ameritrade: Mobile Trader Review

Intuitive UI and all the functionality you could possibly need in mobile trading software. On iPhone X, the bottom control tray is obstructed by the system-wide ‘home’ indicator bar. Thus, tapping on an icon sometimes triggers the home bar, resulting in you being taken home, activating the app switcher/reachability, etc.
