Here is a concept that needs to be explained to you first. The paper gold you are doing is a kind of trading leverage, that is, futures trading. During the trading process, it is completed in the form of margin. The usual process That's right, if the price is 300 yuan/gram, the trading leverage is 10%. The minimum unit for trading is 1,000 grams (the minimum trading unit currently executed in the domestic market). Then the funds you use for one transaction at this time are 300 yuan/gram * 1000 grams * 10% + handling fee of 10 yuan = 30010 yuan. This is your margin. For every 1 yuan drop, the book loss is 1,000 yuan. If you have 50,000 funds, there will be nearly 20,000 left. When the price drops by more than 20 points, your remaining funds will be completely lost. , although you still have nearly 30,000 yuan in funds at this time, it is not enough to hold the margin required for holding a first-hand contract. The market will ask you to close your position, which is the so-called liquidation. (Ignore here the issue of reduced margin requirements caused by price drops) Unless you make up the amount of margin owed in a timely manner. Can you understand this? In other words, although you still have nearly 30,000 yuan in funds, because you are not enough to hold one hand of margin, the market will think that you are out. And what you lose first is not the margin you used to buy the contract, but your remaining funds. As long as your funds are less than the margin, you are not qualified to participate in the market.
