As wave iv was a triangle (terminal move) and we have clearly five waves to the upside reaching a fair target for wave v, I am confident that a correction or a complete reversal is due at this point. A full retrace of wave v is likely. A break under 1650 confirms a complete reversal for some time. I cant yet say it is a complete reversal with confidence because what came before this impulse is not entirely clear, it could be the case that we just completed wave iii but I doubt it.
