CPER remains in a short-term downtrend; 4021 is key resistance, with upside trend line near 4140-4150.

Okay, let's conclude by looking at the American Copper Index Fund (CPER). In this trade, I noticed a weekly peak tail, which is a strong bearish signal. Since the tail end of that weekly peak, which was roughly in mid-September, we have since declined and that downward trend has been realized.

So, let's move on to the daily chart here. As you can see, since that weekly upper tail in this uptrend here, where we broke through this level, we have been in a downtrend and have not been able to reclaim the 4021 level as resistance.

Therefore, in the short term, this is a key resistance level that copper needs to overcome. On the upside, this level of this trend line will be around 4140 to 4150, somewhere in this area dynamically.
