"Learn the Ropes", it's what you found as most interesting thing in this article, me too. But I think it's not well explained, learn the ropes means a lot of thing, it means to learn the field, where are the borders, the rules, what you can do, what you can do, and to learn about hidden tricks you can use.
When you go trough the comments here and on other places too you will see that many people don't know basic things about trading, but they wish to make profit and be successful, how is that possible?
