We have an interesting scenario here, with the possibility of Nikkei topping, and the Euro on the verge of being devaluated by the ECB's monetary policy.
The setup offers a great risk/reward ratio, so I wouldn't hesitate to take it.
Target is the AB=CD completion from the top to the current sideways range, but it will probably offer plenty of shorter term opportunities to scale in and book partial profits along the way.
Good luck!
