Here we have the on the GBPJPY . This pair had a big drop from June 2015 until October 2016. This drop took exactly 477 days. Since then it has been retracing, but only about 42% so far. The time it took for this? 470 days.
This pair has obviously been making higher highs and higher lows during this time, but we can see that the price and time with each higher high gets closer and closer as time goes by.
Now the idea for this setup about harmony is that we get at least some sort of correction to the downside on day 477 from the obvious low. Let's see what happens :)
