Copper shark attackIf you trust the recent 9/20 day moving average crossover enough to short copper, today's bounce back toward the 9MA might be a good one to sell.
When setting a profit target to the downside, a harmonic trader could project a shark with its C-point (D-point in the diagram) in the neighborhood of 3.5365 (red circle), for about a USD0.25 profit per contract. This would work out to USD625 for the mini contract or USD3125 for the full contract.
If the shark went on to complete by drawing a full CD leg (green arrow to green circle), that would be another USD0.25 to the upside.
