USD/JPY to Follow CAD/JPY in a Triangle Pattern?

It was not easy to decide whether it should be called a descending triangle or a symmetrical one. In reality, it is something in between, but the descending triangle looks to be a more appropriate designation for this USD/JPY pattern because the lower border’s slope is significantly less pronounced than the upper one’s. The formation serves as a long-term consolidation following a year-long downtrend in the currency pair. It is also correlated with the recent CAD/JPY symmetrical triangle, which broke down just two weeks ago.
The yellow borders mark the triangle pattern itself. The cyan line is my potential entry level constructed at 10% of the triangle’s base width below the lower border. The green line is my potential exit level (yeah, the yen at 87.xx indeed seem far-fetched at this point). I will set my stop-loss to the high of the breakout bar or to the high of the previous bar if the breakout one is trading mostly outside the triangle. Needless to say that I will be only taking a sell trade here — bullish breakouts will be ignored because descending triangle is a continuation pattern for downtrends.

Update 2016-10-04 18:30 GMT: I have just cancelled the trade setup for this triangle because the pattern is obviously no longer valid:
