First, buy open positions and sell open positions. When the number of positions opened and closed is finished, it will go up. How much you can eat in the position you buy, it will rise by a few points, and it will be the same as falling.

Second, the second principle is the same as the first principle. The futures market is a sufficient market. According to the specific situation, the handicap is the transaction price and the number of hands rolling on the right. 500 lots of soybean oil is not big, and the sale is closed. If you don't buy at 6520, the price will not change (buying includes buying and selling positions).

3,4 The problem is the same. As long as the opponent at this price is not finished and someone takes over, there will be no price change, just like stocks.

Finally, domestic products are generally linked with foreign countries. Many domestic products without pricing power depend on the trend of the external market. For example, 60-70% of soybeans are imported, and the external market has fallen. How does the domestic market rise?

Sugar, corn, wheat and cotton are relatively independent.
