I would like to request a feature that allows the user to load up one chart, configure one strategy, and then select multiple accounts to which the single strategy will execute orders to so that it becomes easier to trade multiple accounts simultaneously. Including all the functionalities that you would have when using a strategy to trade a single account.
On a side note, I would truly like to see more support for IB's Financial Advisor/Friends & Family accounts, so that one may be able to trade multiple accounts from a single strategy.
