The yen has broken out downwards from its triangle (silver) across VWAP of the megaphone (blue) it started forming in mid-November.
The target is now the blue megaphone bottom, but the existing guideline will almost certainly be redrawn. You could use a normal triangle target here–the height of the triangle subtracted from the breakout level.
It’s possible but not guaranteed that the yen could put in a false bottom at the level of the previous megaphone low. If you see the yen reentering the triangle, it’s going for that blue megaphone VWAP before reversing and continuing down.
