TK was rated #2 of the top ten trading platforms. 1st was a place that specialized in options (not even sure what that is). TDA, ET and SCT were rated 4, 5 and 6 so I went with TK. Ranked highly because of their customer service. As a newbie to investing that was very important to me. At the end of the day there's something wrong with all of them.
BTW - Discussion was about deposits.
