Here is a link to a Market commentary that I read daily. http://www.traderfeed.blogspot.com/ It is written by Brett Steenbarger who says the following about himself -- "About Me -- Author of The Psychology of Trading (Wiley, 2003) with an interest in using historical patterns in markets to find a trading edge. I am also interested in performance enhancement among traders, drawing upon research from expert performers in various fields. " I find his commentary useful. It would be interesting if any of you have any other sites that you read and would be willing to recommend.
