I am personally checking out SMB. T3 is first loss, which means that no matter how much buying power they give you, your actual equity is on the front line for losses. How can I risk a 15% drawdown on $300k buying power, when my personal equity of $20k takes the whole hit? The buying power is useless to me at that point. SMB takes 30-40% of profit, but they give you all capital, and don't mark up commissions. They told me they're getting .0007 per share.
