You can buy as much money as you want, so you will eat up all the competitors at all prices, which will naturally affect the price.

In practice, there will be two situations: short-term influence in the day and manipulation of futures prices in a large period. The former is simply what you see on the time-sharing diagram, and the latter is actually what we often say. The forced opening of positions in the operating market can control most of the spot through a large amount of funds, and then forcibly empty futures, or directly force futures prices through large funds. In short, the premise is that the funds need to be large enough. However, in practice, it is rare to control the market simply through funds, and even if there is, it is rarely successful. To put it bluntly, it is necessary to cooperate with the market environment, otherwise it will be very dangerous. Last year's low methanol futures are a good example. You can look through it and there are very vivid teaching cases. I wish you a happy investment.
