I manage several family accounts. Is there a trading platform where I can make the same trade across multiples accounts at one time?? Such as buy 100 share of APPL or sell 100 shares of AMZN across all accounts at the same time?

You can now do that with Medved Trader using the Hotkeys - the multiple accounts can be with same broker or different ones. doesn't matter.
