Early in my transition from biochemist to technical analyst many of us kept manual chart books. When we were traveling overseas we frequently exchanged market data. In those pre-internet days, there was often more communication between analysts and more concentration on the daily price data.
This was in the infancy of computer analysis of the financial markets so technical analysts paid more attention to traditional methods of chart analysis than they do in today’s markets. Still, I have been surprised that since the bear market lows in March 2009 several key turning points, both up and down have often been ignored or missed.
