for perspective, I have an advanced degree from MIT and have been trading for over 30 years, yet when I look at my trading library I only have 10 books in it, all the rest were given away to fellow traders who wanted that 'hot' book to read. One of the books still on my shelf is Mindtraps, which on rereading seems naive in this age of data streams and pc's. However, that book was written when none of that existed and was for the position or swing trading mentality. Also, there were few Psychology books out then; as such I was fascinated with it. Although I love science and its rigorous nature, all the books on my shelf are devoid of formulae, and so is my trading. I have found that my best trades are ones I put on and let run with me out and about experiencing life and letting the intraday noise do its thing. I came to realize that there wasn't a profit I couldn't take while at the monitor (to my detriment). Hence, I have come full circle and trade only off the daily charts, looking for those minor swings of 3-5 days. Perspective and low anxiety are wonderful things. I treat trading as an art with colors and flexibility, as opposed to a science, and mechanical and 'black and white'. And I feel that is the difference between Tharp and Douglas, Tharp wants one to be rigorous in their approach, treating trading like a science whereas Douglas says its ok to be intuitive and in tune with oneself as you approach trading. Two approaches, similar result if disciplined. I guess if you look at your trading library you will know quickly enough how you approach trading.
