When look at weekly chart short trade looks even more possible. I marked important GAP's on the chart. I marked in circle place where GAP acted nicely as the support/Resistance area. Last three highest highs are creating rounded top which is another signal for sell in my opinion. Pair is strongly rejected after it touches GAP on weekly chart marked.

Blue GAP is another strong ressistance/support area.
