I have joined Rob Hoffman's trading room in Jan 2011 and can verify the previous comments. Till today, April 27th 2011, he has not had a single losing trade in the 4+ months since I have been a member. And I have bben in the room every day. Secondly, he only takes high probability trades and if the setups don't oocur then he will not trade. So, yes, there are days when he does not take any trades such as today (FOMC day) and yesterday. But, there have been days such as Japanese Earthquake etc when he has made $21k in a week. He trades live on his real account in full view of all and doesn't trade a simulated account or announce his trades after the event.
However, membership to his room will not suit everyone. It particularly will not suit those who just wish to take trades every day or just copy Robert's trades irrespective of thier account size or psychological abilities. It is suited to those who wish to learn patience and only taking the trade when the setup is right for their account size and their psyche.
I just felt to give some alternative perspective form someone who has seen Robert trade every day for the last 4 months. I have found Rob Hoffman to be a successful trader who has / will go out of his way to teach his techniques / setups to his 'student family'. This is also true of John Carter and Hubert Senters.
Incidentally, I also first heard of Robert through the TTM's 3 day free webinar to intorduce Rob Hoffman. I had NO problems logging in every day.
