This is my best interpretation for now. I consider we've seen the top at nearly 26,600, completing wave 5-(v)-v advance from the year 2009 low. From 26,600 I can count 5 waves down to 23,350 -wave (i)-. The next few days market rebounded to 25,805 as a countertrend move - wave (ii)-. If we consider that the next impulse wave (iii) have started at 25,805, price should quickly drop to as much as 20,580 (1.618 times wave (i)), or at least 22,575 (in that case, wave (iii) would equal wave (i)). It should happen this week.
