When you create a linked account, the accounts are linked by a common User Name and given User Name can log into only one session at a time. It is only after login that the User defines which account he wished to act upon (through a drop-down window in each of Account Management and TWS/WebTrader).
To accomplish what you are attempting, you would need to create a second User. The upside of this is that you can maintain separate sessions withthe two logins; the downside is that it entails a separate User Name/password combination as well as a separate billing for market data.
There are two types of additional users: a second user of the master (typically used for API purposes) and a power of attorney user (typically used to provide another famility member with access to your account). For instructions on the former, type KB1004 into the search engine on our website, for the latter type KB1001.
