Anyone know of any good books on the following:

1). Trading psychology --I want to better identify my personality traits so I can trade accordingly.  Or become more aware of any flaws that may hamper my success.

2). Designing and backtesting mechanical systems.  I have learned a lot here at BPT about staying with the trend, and being mechanical to eliminate emotion.  But I think I can learn even more if I go through the complex process of creating mechanical systems.   I am not even clear how to backtest somebody else's system.  I just want to read what I can on backtesting without spending money on some expensive software that I am not sure I can even trust.

FYI.  Reading this PDF from the original Turtle Traders prompted my post:  http://bigpicture.typepad.com/comments/files/turtlerules.pdf

Love to know what people think of it as well.
