What is talent anyway? It's nothing more than the ability to excel at a particular activity. In order to do that, you have to have all the pieces of that particular puzzle whether you are born with some or all of them or have to acquire them. In the case of trading you need to start out with a fair level of intelligence, then be able to use that intelligence to develop a consistently profitable methodology through observation, testing and relentless pursuit of the truth. In short you need desire, dedication, discipline and perseverance. If it's not your passion, then do something else because you most likely won't have the financial or psychological resources to make it through the learning curve which can take years.
