I believe this has got to do something regarding trading where you are not able to cop up the stress that comes in when your trade goes wrong? 

If there were books like that then this world would have been easier mate. The stress is your emotional response to what you do in your everyday life and I guess you should be watching out that by all yourself and not by reading any book. You can spare some time over your body calming by doing some Yoga and stuff life that.

In any case your emotional easiness should always be there to make successful trading.
