Hi. I just wonder if there's any valid reason why authors sell their trading systems. Recently I'm googling for "momentum trading system". This website came in front of you in the search result: http://www.stressfreetrading.com/ Did you use the system? Is the author trustworthy? Does the system work? I just wonder if there's any reason for the author to sell system if it DOES work. Why doesn't the author keep this for himself and win big? Thank you! PS: - I just ask for information. This post doesn't imply anything, including the quality of the website. - After all, it might be a scam!
