I currently have a margin account with IB and am seriously thinking of transferring two IRAs, currently at Etrade, to IB. I have emailed IB customer service but have not yet recieved a response. 1. What is the quickest and most straightforward way to transfer accounts to IB from another brokerage? 2. Can all of my accounts be traded using a single login and a single instance of the TWS? 3. One of the IRAs belongs to my wife. Can it be linked (with her permission, of course) to the others under a single login and instance of the TWS? I am trying to avoid having to log in to multiple accounts and the necessity to run a TWS for each one. I searched but could not find this information in any of the material posted on the website. I did notice that there is a space on the order screen in TWS to specify the account number which gave me cause to hope. I would appreciate any response from people that have had experience in these matters.
