There are a few great statements to share from this book but I am definitely recommending this as one of the most important books for struggling traders -- especially those trading futures.
Every trader needs a good mentor when starting out. If you don't have one (in person), at least start with this book.
Two key ideas (which will make more sense if you've read the book):
1. Anything can happen.
2. You don't need to know what's going to happen next to be a CP trader.
