Let me offer you some perspective. Pre-market and now after-market is influcened (and indicative) of overseas trades. Way back in the mid eighties or so__John Dessauer published an indicator based on the first hour and a half trading volume. We have now taken this concept and developed a program to evaluate cash flow starting with the GMT+12 markets and follow them West. We evaluate everthing; but the most important is the Forex and country specific debt flows (bonds). With this analysis I can make a judgement if a starting rally will hold or fold. Experiment with the concept and become aware!!
