Risk Warning: Bulls: ☆ Short Risks: ☆ Tips before the market: Orient: Copper: Due to the market's expectation of the Chinese government to raise interest rates and the appreciation of the renminbi, it triggered profit-taking in the market, causing the LME price to fall by more than 100 US dollars yesterday and rebounded late. Compared with the previous trading day, it closed down at US$3090/ton, which was a drop of US$48/ton from the previous trading day. The fluctuation ranged from US$3146.5 to US$3030 per ton. LME copper stocks fell by 325 tons to 89.875 million tons yesterday, and the continuous decline in stocks is still supporting copper prices. Yesterday, domestic copper prices fell sharply, and all contracts were closed at the stoppage price. The main reason is that there is news in the market that the renminbi has widened in the range of fluctuations in the near future and promoted the process of marketization of the exchange rate. The implementation of this measure in the current situation is very To a large extent, Bush’s call to Hu Jintao deepened the market’s expectation of the election card on Bush’s exchange rate issue before the US general election. On the other hand, today's National Development and Reform Commission’s clear remarks on the fall in commodity prices in the fourth quarter have also induced market speculations on the exchange rate issue. The market has rumors that the People’s Bank of China will raise interest rates on a certain Saturday in late-to-late October, China’s exchange rate policy and interest rates. Changes in the policy will be the key to the recent evolution of copper prices. The spot price also fell sharply yesterday, at 31,400~31,500 yuan/ton. Aluminium: Affected by profit-taking, yesterday's aluminum prices in LME also fell sharply on March. The main factor is also concerns about the RMB exchange rate. Domestically, Shanghai Aluminum was affected by the expected bad news yesterday and dropped sharply. Each contract closed at its daily limit. From the perspective of the market, aluminum prices showed a significant passive character of copper drag, holding positions continued to decline significantly, and trading volumes continued to remain moderate. In the short term, the aluminum price will show a turbulent trend. The domestic spot price quoted yesterday was 16850~16900 yuan/ton. Ma Hongqing: cu: Affected by the sharp fall in Shanghai copper, LME copper prices fluctuated sharply on Tuesday's trading. The profit-taking sell-out once swallowed up the gains on Friday, but the spot premium did not weaken with the price. The sharp decline, the squeeze contract behavior of the spot contract is still controlling the entire market, so in this regard, the sharp fall in copper prices on Tuesday can only be seen as an adjustment to the previous rise, it can not be asserted that the formation of the head. However, after a sharp turbulence on Tuesday, if the copper price can not be re-stopped on the 3150 in the short term, the copper price in the afternoon market may further decline. Technically, it indicates that the price of copper is still in a strong upward trend. It will take time to change the trend. The strong support provided by the 2980/3020 front line will curb the fall in copper prices in the short term. Only when the current price falls below 2850, can we think that the price of copper is at the top, at least in the short term. Shanghai CU CU is expected to be in the range of 29000/29500 on Wednesday. Once the price falls below 28800, it means that copper price will further test the important trading range of 28000/28500. Investors are advised to wait patiently. AL: Domestic aluminum prices fell below the sharp decline in copper prices during Tuesday's trading. However, LME aluminum prices rebounded from bottoming out in the evening trade. In the past few weeks, the size of the LME aluminum market has appeared. The huge Masukura situation has brought difficulties to the further rise in the futures price in the short term, but the increase in the spot premium implies that the probability of aluminum prices falling sharply will be less. Technically, the aluminum price in the indicative period will be less likely to break through 1850 in the short-term, and aluminum prices need to fully accumulate in the 1800/1850 region before re-raising. Shanghai AL AL501 is expected to remain within the range of 17,000/17200 on Wednesday, with further support at 16800. We recommend investors to follow up on the 16900 first-line covering Tuesday's closing position or when the current price breaks above 17300.

This is crucial. Snow pointed out that currency is a key factor in global trade. The United States hopes that China will stop the peg against the US dollar policy. China is considering this plan and the United States will continue to closely monitor its movement. From this point of view, domestic copper has a potentially big negative factor.
