He didn't ever give away his trade secrets, because he devoted much time and money into them. I don't think Apple would come up with a new product, and tell Samsung what they're going to do in advance. Would a company release earnings reports to investors, or leak any secrets out in advance to anyone. What is Gann doing providing a newsletter service, and selling books anyways in the first place. This was a man who already accomplish his trading, so he was a man who treasure knowledge and guarded it. Perhaps he just wanted traders to learn a thing or two, and because he belong in the world of trading for years. He never wrote book until he reach his 40's, so this is to say he have master his trading in his 20's and 30's. I know this is possible for the fact that I have discover a Master Time Factor all unique like Gann.
