Lets start off by taking an indepth look at the INDU as a proxy for the other US stock markets. A year ago this month the INDU put in an important low which has held support. A very strong rally ensued which took the INDU up to the 17,975 area where it topped out and began another strong decline. This next decline ended in the same area as the August 2015 low and formed a double bottom which is a reversal pattern.
The next rally phase took out the previous high by 200 points up to 18,167 where the next decline began, but this time the bears could only push the price action down to the 17,330 area which looked like it might be an important low.
