I'm a retired guy living a nice life between Italy and NY. I've been trading on and off for years, with varying success depending on the level of attention and my state of mind.
I have, therefore, a ton of experience on human mistakes and emotional issues connected to trading. Too bad nobody talks about that. While everybody is looking for a trading system or method what escapes most is the importance of their own emotions.
I am paying attention to that and doing well so far.
