Futures can be bought first and then sold, or sold first and then bought. If you think the price will go up, buy it first, and then sell it for profit when the price goes up; If you think the price is going to fall, sell it first, and then buy and close the position when it really falls, so you can make a profit.
Futures is a two-way transaction, no matter whether the price goes up or down, there are opportunities for profit. There is no fraud in the stock market in the futures market, because there are no false profit annual reports and false mergers and acquisitions. Only the price of goods is changing.
Futures trading adopts the margin system, and the usual margin ratio is 5-8%, which means that you can use 5-8 yuan money to do business of 100 yuan, so you have leverage and great risks and profit opportunities.
