For the next four Mondays I'll be running my own little spin on trader psychology. I have no illusions about being even close to par with Brett Steenbarger's Traderfeed, .....I am a mere bug on the windshield of his tireless and sophisticated probings into the trader pysche,........but, after 20 years of trading, and in the spirit of blogging, I wanted to offer some of my observations about why consistently successful trading is elusive for many of those who attempt it. My goal is to examine some aspects of market dynamics often overlooked by traders that may confound their efforts and to offer a few tactical suggestions for performance improvement. The first installment is The Castanza Problem.
