Nikkei - Yen correlation

The Yen and the Nikkei have been moving together for many months now. Actually the Yen has been leading the major price moves by a few trading days. The correlation can be seen in the symmetrical triangle that began back in May. Notice how the Yen tops and bottoms before the Nikkei. These moves are most obvious in points A, C, and D.

Currently the Yen is trending down while the Nikkei is still trending up. If the recent pattern hods, we should see the Nikkei move down in the next few days.
