Although the navigation through Thunder Mobile Trading System's interface is intuitive and similar to any other mobile application you may have used, we would like to point out a few nuances.
The four main functions one needs to know about while using Thunder MTS:

Scrolling -  For example when in the Accounts Screen user may tap and drag in order to to scroll through the entire list of active Accounts.

Tapping - In order to select a certain field, button or bullet box on the screen the user has to tap on that particular area of the the mobile device interface. (The "tap" is an equivalent of the desktop "click")

Main Menu - User may access the Main Menu of the application at any given point, but tapping the Main Menu button on the bottom of the screen.

Back button -  To return to the previous screen from the Main Menu, user may tap the Back Button, available at the bottom of main menu. 

Log Off - User may exit the application by tapping the Logoff button at the bottom of the screen.
