Forex trader wanna-be's (myself included) often need a reality check! Reality check number one is that you will not become an expert overnight, in weeks or even months. I would however argue that perhaps one could master an apprentice level trading status in as little as "months" if the person had a personal mentor, trading at their side to guide them. Such is not the case for most, and even then it would still take years to master trading, depending on an individuals temperament.
One article I found I think said it best, "Forex, it cannot be traded by just anyone, it is a science, an investment science, a special logic of money flow and economic rules, it does not exist by default in everyone’s head."
In other words, it takes time and even then some will still not learn to become a successful trader. Special thanks to the Forex Dark Side for his shared wisdom, which is a great Forex reality check!
