This move up does not look as impulsive as I thought looking at the 4 hr chart. It could still be playing out in a leading diagonal. Another thought is the pair could be doing a WXY rather than ABC so the move up from 1.42641 would not have to be impulsive.
I am just going to watch it play out, if it gets to 1.5200 to 1.5400 I will add to my short. If it breaks 1.42641 I will add to my shorts...
