Took Partial Profits in NUS today as it approached 55

Been following NUS for a few weeks and opened a long position at 51.10 on 3/15/17. Sticking with my original strategy, I took partial profits today at 54.72 as I believe the area of 55 will act as some sort of resistance. From here, will close out the position on a pop above 55 or if it pulls back enough to break the short term up trend.
