I just opened an account with IB, which I will use as a second account to trade with starting in 2008. I received a confirmation e-mail saying that the account has been opened and that they are waiting for my deposit to finalize the deal. I'm going to mail in the initial deposit check today. Are they good about sending out the STP device promptly? Also, can I play around with TWS and use the simulation mode right now without a code from the STP device or I have to wait ?
