I do not think that the professions offer a sound base from which to practice market trading. In fact, they could be a drawback because of the illogicality of markets. Markets do not do what common sense, from a mathematical point of view, dictates.
That is why, IMO, systems will never work for more than a handful of traders who know how to interpret them.
It does not matter what your academic qualifications are. It only matters that you are an intelligent person capable of approaching trading from another angle and, whatever that angle is, it will be difficult to teach to others. A few will grasp it but most will not.
If we become successful traders, we must be thankful for that. Very few will understand what we do. Perhaps, we should be thankful for that, too.
