EWJ - How to identify a plausible target

This idea is for investors as I'm analyzing the chart in weekly and trying to identify fair targets for a long position. First you need a donchian line which is basically the middle between the highest high and the lowest low during the last 52 weeks.

Using this donchian line (nb. which is part of Ichimoku system as SSB line), you then identify the last "cycle" which is a clear half-wave with well-defined bottoms/tops. Applying the Fibo retracement tool using the top-bottom-top (or bottom-top-bottom) points of the identified wave, you'll end up with a set of Fibonacci levels. The different levels above 1.0 can be used as price targets as shown here.
