It is an objective fact that the United States is a big corn planting country; However, whether the trend of domestic corn futures follows the domestic market or foreign markets is generally considered to be influenced by the United States, but I personally think it is difficult to say:

First, the futures trend is not necessarily positively related to the spot trend, that is to say, the futures will rise if the spot does not rise; This involves that the essence of futures trend is that the laws of nature determine the laws of the universe, affect the earth's climate, affect the events on the earth, affect people's psychology, affect the banknotes in people's hands, and affect the futures trend chart. Personal point of view.

Second, there is a certain correlation between fundamentals and futures trends, but personal operation can't solve a series of problems such as how real the information is and whether the information is timely; Even if it can be solved, there are still problems such as different levels and angles of information cognition of futures groups; In other words, for short-term trading, fundamentals cannot solve the problem of accurate entry and exit positions required for short-term trading; Of course, if you are in the medium and long term, fundamentals are indeed valuable, but they are not necessary, because there are traders in the medium and long term trading who don't care about fundamentals at all.
