This is what I consider to be a best case scenario. B has retraced 61.8% of A and could turn here. If it does, the simple 1:1 relationship targets $C1704 close to trend line resistance. Assuming further short term strength in the C$, I can see a very quick spike in gold to perhaps $US1380.  This will confirm negative divergence in the sense that the commodity currencies will still have a lower high relative to their June high whereas the GDX will have a higher high. Also GDX will likely be hitting its trendline resistance then so I would be looking for a quick reversal of any spike.

Note that this is the reverse of 2015 where commodity currencies made higher lows and the GDX did not. Commodity currencies were forecasting increased miner profitability at that time.

If we close below $C1570 then this projection is unlikely to play out and below $C1550 is pretty much a confirmed miner short with the downtrend in profitability likely to continue for awhile
