do you have some good books on this subject (sports psych) to recommend?
Quote from lurefo:
Most of the best traders in the world have written on the subject and they disagree with you. Unless your strategy is 100% automated, trading is all about psychology.
Even with the best money management techniques and a solid trading stategy, 90% of the traders will screw up. You know why? because our actions are driven by our emotions and our state of mind wether you are aware of it or not.
Your car analogy is bad because of the above. A car does not think. A car doesn't have emotions. It doesn't get mad and do stupid things. If you want a good analogy, take professional athletes. If you have done any competition, you know techniques don't make the difference. But psychology does.
