What do you guys use as proxy to measure copper? JJC seems very illiquid that it doesn't seem accurate to track daily ACD levels on this ticker.
I think you need to be careful with data like this. As you increase the time, you increase the noise factor in the data. That's one of the things that makes ACD so effective is the granular analysis at the daily level that gets extrapolated to larger time frames. Not the other way around, i.e taking data from longer levels and extrapolating to the daily level. Just my opinion.
If any of you are wondering, WTI confirmed 3 days ago. Also about to confirm monthly A up.
