EURUSD formed a falling wedge, both lines are downtrend. The angle of descent is steeper on the resistance line. The pattern form highs lower than previous and lows lower as well. After a few attempts, the prices finally break through resistance.
To confirm the breakout, the price should close above the resistance line, if so, make a long. The profit target is the distance away as the back of the triangle.
Is there any other way to find profit target rather than use "back of the triangle"?
