Getting Set Up with the J-Trader Platform
J-Trader is accessible in two ways. First it can be used as a stand-alone application. The software can be sent via a CD or in a zip file, then installed on your computer. The application can then be launched either from the Start menu or by double-clicking on the J-Trader desktop icon. J-Trader can also be launched as a hosted web-based application. In this case, the user clicks on a web link and the latest version of J-Trader is downloaded as a Java Applet. After logging out of J-Trader, the application is no longer physically on the computer. An advantage of the hosted web-based application over the stand-alone installation is that the user always gets the latest software version when he or she logs in.

The main screen of J-Trader, shown above, allows you to select windows, configure J-Trader's appearance and behavior, and log off.
Default Desktop lists the "desktops" or trading environments available, with the currently selected desktop highlighted in yellow.
Desktops are saved selections of trading screens and instruments. Multiple desktops allow the trader to move quickly and easily between different trading environments.
For example, one desktop may cater to a particular asset class, such as foreign exchange, while another caters to fixed income. When logged in, J-Trader will automatically show the last desktop that was used.

The Settings button brings up a screen for configuring a wide variety of user options such as alerts, default order types and fat finger error limits.
