There is story about a floortrader that believed he had a connection trough a Coca Cola bottle with aliens that tell him which way the market would go. When he was wrong, he blamed it on the connection. He was a very successful trader for years. In retrospect, he just ride his winners and cut his losses quickly. Moral of the story? It doesn't matter what you use for predictions in trading, as long you follow the sound principles of trading. If, that is true, why would you spend all the time in the world on trying to find a system that could predict what is going to happen? And when you find such a system, trying to convince others that this one is the best? There is no money in being right.
