There is basically no banker's control over futures, but some customers with huge funds use various price schemes to trade and flow, which leads to retail investors following suit and confusing the market. For example:

Folk rumors: When the copper price of a big businessman in Zhejiang hovered below 30,000 after the Spring Festival, he got 65,438+10,000 tons of electric copper from the spot market. There are three assumptions:

1, big businessmen have great wisdom and are not for the state reserve;

2. After the Spring Festival, the position of Da Yue seat copper is basically owned by big businessmen;

3. One third of 3.LME's recent trading volume was created by China Fund. Prior to this, the trading volume of LME domestic funds was very small, even less than 10%. European and American funds basically did not participate in the rebound in the first quarter (this assumption is basically close to the truth).
