After rallying about 80% off the March lows & while still in a confirmed update, copper finally appears to be setting up as a decent swing short trade opportunity. While it is best to wait for the sell signals on copper futures (below) as well, CPER (copper ETF) will trigger an objective short entry on a solid break and/or daily close below the steep uptrend line (and bearish rising wedge pattern) on this daily chart.
For futures traders, a sell signal on /HG (copper futures) will come on a solid break and/or 120-minute close below the primary (first) uptrend line (as this is a 120-minute or 2-hour period/candlestick chart).
A longer-term swing target on /HG copper pending a sell signal on a break below this daily bearish rising wedge pattern would be the 3.1087ish level with a potential second target around 2.9641.
