Well, LZ is right, because futures are margin transactions, which means you can do all the transactions only by paying a certain percentage of money. How to calculate the profit and loss of margin trading? For example, the leverage of gold futures is 10 times, which is 10% margin. If you want to buy gold futures 1 lot (1 lot = 1 ,000g), then the margin used is 1 lot ×65438+. If gold rises to 400 yuan/gram in the next period of time, then your profit is: profit =/kloc-0 /×1000g× (400 yuan/gram -300 yuan/gram) = 65,438+ten thousand yuan. In terms of profit ratio, if the trader adopts the way of firm trading, he will buy 65,438 at 300 yuan/gram with 300,000 yuan. When it rises to 400 yuan/gram, the profit will be 6.5438+10,000 yuan, that is, (6.5438+10,000 * 654.38+ 000%) = 33.3%, and the profit of margin trading will be (6.5438+10,000) × 654.38+.

Of course, if you lose money, for example, if you drop by 280 yuan/gram, you will lose 2W. Originally, the spot 30W lost 2W, but now 3W lost 2W, and the obvious loss was magnified by 10 times. Therefore, LZ should pay attention to buying futures, and leverage magnifies the benefits as well as the risks.
