You don't need to follow a such course, just learn from any sources both videos or articles. Online won't learn us about experiences, it is all only about theories. If we want to know the theories, there are already many sources to read. What we should know is the experience, it can be from experts or from our own trading. Experts won't offer newbies to learn them online, most of them keep their identities. So, we can expect much if the online course is trustable.
