The principal benefits of linkage are ease of access and potential savings in market data subscription fees. Following linkage, all accounts will be accessed via a single User Name, password and SLS device. After login to the trading platform or Client Portal/Account Management you will be provided with a drop-down window for choosing the account you wish to trade or perform administrative tasks thereby eliminating the need to memorize multiple login information or manage more security devices.
Additionally, as market data subscriptions are billed at a session level (i.e., User Name) and only a single TWS session can be viewed for any one user at a given time, account holders previously maintaining duplicate market data subscriptions for multiple accounts have the opportunity to consolidate those following linkage.
