"Will anyone move $5m from their top tier brokerage to Double yet?" I have! But I understand that yes this is a hard thing to get people to move and trust, safety and trading mechanics are incredibly important. We are trying to be as transparent as possible on all those factors. I would love for you to try us out with a smaller amount first to see observe all the mechanics before making a larger move. We support full and partial ACATS transfers of existing stock positions (meaning you don't have to sell anything).
