Steve from IB responded via email to me, saying this new IB feature would probably be available only to Registered Investment Advisors when it first starts August 1st. That being the case, does anyone know another alternative for handling/managing separate accounts similar to this? This sounds almost perfect. Everything goes to the true account holder (ie. tax, etc), and the power of attorney is allowed to trade all clients on one platform. Any other possibilities that work as nice?
