Here's another good book.
The Psychology of Trading - Brett N. Steenbarger
Actually one of my favorites. It has a different approach to explaining trading psychology.
Another book I recommend is:
Exceptional Trading - Ruth B. Roosevelt
Recommended by a trading buddy 6 years ago. Worth checking out. She has another easy to read book.
12 Habitudes of Highly Successful Traders - Ruth B. Roosevelt
I own both these books as well.
