Hi Christoph.
To me, it looks a sell setupu. It looks Wave 5 is completed at 87.533. Then the big down movement (87.533 - 84.649) looks an Impulse Wave A which has already broke a uptrend structure. Now it looks forming wave B. This wave B looks a Zigzag pattern. The subwave C of the wave B looks just about to start upward. The second retesting point which you considered as long entry point looks a starting point of subwave B of the wave B, which can go up at least 100% of the subwave A of the wave B, which is about 110 pips. The chance of starting another big down movement, which might be at least the same big size of wave A. Please excuse me if you do not like my comment. Good luck.
