This is not a directional trade idea, but a relative spread trade.
-The extreme preformance of European equities over US SP500 index has been clear so far this year. However based on Heikin Ashi signal (including haDelta/SMA3), chance for short term trend break, and possible Slow Stoch cross I'd say it is time to buy SP500 vs selling Eurostoxx50 Index, at least for a short term spike.
