Duck,
I was a broker for many years. And will never go back. Like a wise man by the moniker of Blind Hog said, 'It does not matter how honest or good the broker is, he is only as good as the clearing firm".
Another wise man who wrote the book "Trading Chaos" told me that regardless of skill or knowledge being a broker creates a dualism. And a dualism will always impede a trader. Sure enough my trading ability increased exponentially when I quit the brokerage biz.
Trading-U will never be more than it already is: a true trading education company that is affordable. The key for me is it only takes up a few hours per week of my time.
Thank you for asking.
