The EXANTE trading platform allows you to link various modules and easily switch between instruments and accounts.
By Instrument
The anchor button 
next to the name of the instrument in modules 'Chart', 'Order', 'Click-Trade' and 'Market Depth' allows you to link various modules:
Anchor button
If you click on the anchor button in multiple modules and change the instrument in one of the modules, it will automatically change the instrument in the linked modules as well.
Example: If you link, i.e. pressing the anchor button in the 'Chart' and 'Orders' modules and choose to display a different instrument in the chart, the same instrument will simultaneously appear in the 'Orders' module.
By Account
The chain button 
next to your account number also allows you to link various modules.
Link by account
If you click on the chain button in multiple modules and change between your accounts in one of the modules, it will automatically change the account in the linked modules as well.
Example: If you link, i.e. pressing the chain button in, the 'Portfolio', 'Margin Report' and 'Summary' modules and switch to a different account in the Summary window, results for the same account will simultaneously appear in the 'Portfolio' and 'Margin Report' modules.
