What is contract or future trade?

So what is a contract transaction? Contract trading is similar to futures. You can buy up or down, T+0 trading mechanism, and you can trade with leverage. Some people may not understand leverage. Let me give you an example: If you only have 500 US dollars, but you are very optimistic about a product, you think I want to grow and earn value-added space for this product, but the funds are not enough. The fundamental difference between contracts and spot is here. You can use very small funds to buy and sell the rise and fall of high-value products. But when you buy or sell this product, the product does not belong to you. What you have is the ownership right of the rise and fall of the product. . It is very similar to futures in nature, but there is no delay and it is traded in real time, so it is also an independent trading mode.
