As a sideline to my 'normal' daytrading activities, I do use these guys as well.
I was introduced to them by a friend in the US. The subscription costs me 125 euros a month. I would pay double that.
There is a profitable way to use the info that they give each week, but it's not how they tell you to use it. I have one trade on a Monday, and that's it for the week. If you look at their 'history' page, you'll spot it as well.
BTW, I have no connection to the company, but if any of those guys ever come over here, I'll buy them a Sam Mig Well....
