I have been using two blogs that have been extremely informative and helpful. These are my go to blogs. 1. www.crowderinvestments.com/blog/ He uses a daily overbought/oversold measure that is very helpful over the short-term plus his commentary is very informative. Also, he jas been mentioned in the WSJ so he has some credibility. 2. www.thekirkreport.com Possibly the best all-around financial blog on the net. HE covers it all and his link lists are wonderful. Mentioned in Barron's.
Some new blogs: http://blog.afraidtotrade.com/ Really good with strategies and entry/exit rules etc. This is one of my favorites http://optionstheeasyway.blogspot.com/ Another one I like for good lessons on trading and charting especially "flags". Amazingly profitable! http://buttonwood1792.blogspot.com/ Good stuff! others i read regularly: Trader Mike Bill Cara etc. and of course how could I not mention my own blog? Mine is more a diary for my own good, but you are welcome to visit if you have the time: http://lauristonletter.blogspot.com/
