On Wednesday, LME base metals failed to shake off the impact of the strong dollar and the stock market decline. Although the US economic data was better than expected, most of the gains were still retreated. Three-month copper hit a high of $6,408 in intraday trading, closing at $6,295, up $40. Recently, Shanghai Copper has basically followed the trend of the external market and has no obvious sense of direction. Today, after the main contract 09 12 opened lower, there was a narrow range of fluctuations among communities throughout the day, and most investors held a wait-and-see attitude. At the close of 49690, it rose 60 points, and the K-line harvest revolved around the cross star. On Wednesday, the US Department of Commerce announced that orders for durable goods in the United States increased by 4.9% in July, with an estimated increase of 3.0%, the largest increase since July 2007. The sales of new homes in the United States increased by 9.6% in July, and the annual rate of 433,000 households was better than expected. The continuous positive has boosted the confidence of investors and is the key factor supporting the current high price. Judging from the demand situation, the price before the target has been higher than the expected level of fundamental support. The current favorable conditions are being absorbed by the market. Once the benefits are exhausted, the pre-calculated price will return to the fundamentals. Although the current copper price is still strong technically, considering comprehensively, it is expected that there is limited room for copper price to rise. In operation, it is recommended to reduce more orders on rallies in the early stage. For example, after reaching the goal of $6,600, Lenton can leave the market in China completely, and there is no need to pursue more operations. Aggressive short traders can sell short positions on rallies after reaching the upward target of $6,600, but there are risks. It is safe to wait patiently for short opportunities after the shape of the falling head is established; Intraday and short-term trading can follow the short-term operation of the external market, but it is not recommended to leave orders overnight.
