why don't you study charts with TA of S&P500, DJIA, NAS, DAX, FTSE, CAC, etc on various time frames from daily upwards of the times when these indexes have topped/bottomed and what are the comparisons that can be seen? When you do that look at the chart of S&P again and you will realise that it's not ready for a reversal based on TA (pullback is a different matter), fundamentals are reflected in charts, so not much call for researching the eco data, chances are you won't understand it fully anyway and what's more important the effect it has on the markets. Absence of follow through beyond 1408 and an intraday double top do not mean that the market has topped, intraday perhaps yes, but making a statement that points out absence of bulls on Friday can be argued by saying that there were no bear action either.
