No worries, I've never done comparisons this way, and I'm sure there is a more suitable one to use than MACD.

Here's a closer look, may be a little tough to discern much from this one specifically.




If I unlink these next ones so it's not an "absolute" percentage comparison, but a more a reflection of it's own volatility and trend, it probably gives a clearer view of their recent similarities (I'd call this a little more of an artistic comparison than a straight scientific one). Put simply the 2 lines use different scales so direct comparisons are not strictly accurate (so a 30% move by copper potentially looks the same as a 10% more by the yuan for example, the size of the move is more a reflection of movements against itself for the period visible on the chart). Not sure if that makes sense.

Left scale = Yuan, Right = Copper. 


Here is a 1hr version which shows more detail. 


Here's from 2017 onwards, also showing some interesting correlations.
