Well JW, thatâs a lot of questions, I'll see if I can help.
I don't have a forex account there but with a futures account with TOS your money gets moved back and forth to a Penson GHCO account. The problem is they have an arcane way of moving unused money back to your securities account, which is where you need it to earn interest. Whenever I have a problem I just send and email and they move back any unused amount. As for rates and interest vs. IB I get better on both at TOS, but I trade, have money, and negotiated with them. IB and TOS are very different companies and I think always will be, each has its own strengths and weaknesses. Since a backup is always a good idea, I would tell people to consider having an account at both.
