Benchmark third-month Shanghai copper fell 1.2 percent to 62,150 yuan on Tuesday. Traders noted LME copper's Relative Strength Indicator stood around 70, suggesting the market was overbought and a period of consolidation was due. "The market's up 20 percent in six weeks and it needs time to consolidate. If we continue that trajectory, the first sign of a fizzle would see a quick return to where we were in the middle of year," a trader in Singapore said.
