For example (the price is nominal), a certain price of Shanghai futures gold was 200 yuan/gram yesterday, so after my analysis, the market would fall, so I opened a position at this price of 200 yuan and made a short position. Then all I have to do is wait for the price to fall. The price really fell to 195 yuan/gram after the opening this morning, and then I don't think the market will fall. What I have to do at this time is to close the position. Even with this short hand, my profit is 5 yuan/gram, the first hand is 1000 gram, 5 times 1000, and the profit is 5,000 yuan.
It's that simple. Just like you look. If you go long in 195 yuan and close your position in 200 yuan, will you also earn 5000 yuan?
