I use TD Ameritrade and Tradeking. Tradeking takes a day and does not leverage via shorting unless I specifically request it, but Ameritrade does. Hence in Ameritrade I can essentially day trade options. I think that overall Tradeking is better...if you were wondering. IMO--it has been my experience that TD Ameritrade has taken some pretty underhanded actions in order to manipulate stock prices. That is why I am slowly transitioning my accounts to Tradeking.
