Does the OANDA Java Test Applet work?
The OANDA Java Test Applet tests your computer for basic Java support and connectivity to our servers. If tests 2, 3, 4, and 5 all fail then it is likely that you are behind a firewall that is blocking port 443, or the network connection to the server is severely degraded. If you are certain that your system should be able to connect please copy the contents of the Test Applet window and send them to technical support.
