?1. Strategy overview since the Sino US trade war in April, the domestic soybean meal market has maintained a pattern of strong range fluctuation. Based on the analysis of the current soybean meal fundamentals and technical aspects, we expect that soybean meal in the future or weak callback. First of all, CSFV frequently broke out in Africa and spread from north to south. The demand of soybean meal downstream decreased. Second, the China Feed Industry Association this week released a group standard for low protein compound feed for pigs and chickens, which will be implemented on February 2 to reduce the consumption of soybean meal. Third, China will lift the ban on the import of Indian rapeseed meal, and more cheap rapeseed meal and Ukrainian sunflower meal will flow into the Chinese market. On Tuesday, China purchased 3111 tons of Indian rapeseed meal. This will occupy part of the market share of soybean meal. Fourth, the price difference between soybean meal and miscellaneous meal is widened, and the amount of miscellaneous meal replacing soybean meal is enlarged. Therefore, in terms of operation strategy, we suggest that soybean meal can be sold in high short position and position can be properly controlled; in case of trend market, position can be added. At the same time, considering that the U.S. mid-term election on February 5 and the leade3294时时彩 rs' meeting between the two countries at the end of next month have an important impact on the market, or bring uncertainty to the market trend. In terms of specific trading strategies, 2212 soybean meal futures can be sold in high short positions. As the 2212 soybean meal options expire in February, they can sell the call options with virtual value to earn time value.
