Multiple Users
Some individuals may choose to have multiple users under a single account. This is quite common particularly for traders who may wish to use the API and the Trader Workstation or Client Portal at the same time. Alternatively, institutions may have a dedicated machine for an automated trading algorithm that a developer would supervise while other individuals are manually trading on the account.
It is important to note that in the last case, individuals can create a limited-permission user which has restricted access from the standard. This would allow somebody like a developer to build out an implementation with the live account without having withdrawal access, or direct trading access. Users interested in creating reduced-permission users can contact the Interactive Brokers Account Configuration team, as listed on our Customer Service Contacts page.
