Recounting this again. The point is that it is still bullish . Working on the Brexit spike down as the low, and the sharp rebound from it as the first move up of C towards 1.50x. A break of the low (1.42479) will wipe this view.

another view. All bullish. I do not see a bearish possibility
It's likely that a low is in. I would mark the 1.4320 area as key support. An alternative view--less likely but possible--is that we have one more minor low to come, just beneath 1.428x, before a move up.
