Futures and stocks, basic analysis and technical analysis are very important. First, let's take futures as an example. Futures variety contracts correspond to spot products, and the determination of their prices is also closely related to the spot, and the price of products is determined by the relationship between supply and demand. If you don't even know some information about the most basic varieties, it is very dangerous to trade just by looking at the technical trend chart. Take the stock again. The price of stock is determined by the value, and the price fluctuates around the value. For a listed company, the value can simply say how much money the listed company makes. If the stock of a listed company is to rise for a long time, then the listed company must have long-term and stable profitability to enhance its value and then raise its price.
