Weekly charts show a classic ending triangle with the appropriate hard thrust down out of the ending 5th wave of wave (E)
Look for further move down maybe to 140, quick move up, then a slower move down toward 114 where the triangle started...over the next several months.
Looks like a wave 3 is still in progress for the Nikkei, retracement shouldn't go below say $36,000-ish before hitting a high of $58,187 to complete the 5th wave.
This 5th wave completion may be only the ending 3rd wave of a larger wave pattern.
Let see what happens in the coming years.
Watch $106.26 as the next target and retracement level. A reasonable pullback can take us as low as 104.37. We may push straight up to 107.57-ish. That is where we should look for a significant pullback or pause. But I can see $104.37 as a support level.
