Since the higher high fits so well in the uptrend resistance, i made another study on the percentage of increase of the current high compare to previous high. The Oct 2007 Top is roughly 20.14% higher than the Jan 2000 top. So extrapolation of this 20.14% from the Oct 2007 high would give me roughly 17051 points in DJIA .
Last clue, the 17151.56 was well REJECTED! Hence, I am >70% confidence that i am ready to be in short position fully noting that DJIA might make another high again.
