Hello, why do you want to buy futures when they go up and sell them when they go down? Is it the principle of buying low and selling high? Please tell me, thank you.
Compare futures and stocks. Futures is a two-way transaction, which can be short or short. When the price rises, you can buy low and sell high, and when the price falls, you can sell high and make up low. You can make money by doing more, and you can also make money by shorting. Stocks can only be bought first and then sold, and prices can only be profitable if they rise. If the market price falls, it can only be a stop loss.
