This chart presumes one more fast ramp by SPX to 2620, then a sharp 18% fall wiping out all the Trump gains. This would be followed by a 50% rebound, and then further falls into the next few years, eventually reaching the 2007 high of 1572.
For example a piece of news (in the right direction) may rapidly accelerate a trend, a piece of news in the wrong direction may stall the trend, and it may need the next piece of news to continue it. On the long-term charts (like this one) it's not so much of an issue as there's good and bad news every week.
But note I need 100 point spike down/up even on June 18th. Chances of that happening are virtually zero, so the chart probably won't behave like that. The reason I posted though is that when you take the fractal into the future, the future predicted pivots fit very well with existing support points and technical levels (ie 50% retracements).
The thing is, that these things work until they don't at which point I abandon them. Some have worked very well in the past. Everything is about looking for a distant target, then I trade with a tight stop in fairly small amounts. This is a long-term one, most of my fractals are 1H charts, looking to stay in the trade about 3-4 days. Check the others, I am getting (a little) more than half of them right, with RRs above 2:1.
As for this particular pattern, I also see there is still a lot of upside for the Dow\SPX and subsequent decline similar to Nikkei 90s both price- (> 50%) and time-wise (> 2.5 years). However, I see we have some more time to reach the top at least till Mar'18 (June at the latest). There will be a small correction (< 10%) till November and then a big move similar to the one we had post-election.
