The "used advance payment" shown in the figure is the deposit. In foreign exchange transactions, the margin system is adopted, that is to say, the standard hand of the euro against the dollar is 65,438+000,000 dollars, and you don't need 65,438+000,000 dollars for the next hand, you just need to pay a part of the margin. Use 750÷ 100000=0.0075, (0.0075=0.75%), and then 1.0075 = 133.3333. In other words, the leverage ratio of your trading margin is 1: 133.3333, which is just calculated as 0.75%. 100000×0.75%=750, so 750 is your deposit. You can ask the company that opened your account about your leverage ratio.

In the picture, you placed an empty order (making money by falling), the point was 1.35438+0, and then fell to 1.5725. 1.3599 1- 1.35725=0.00266。 When your displayed price reaches five decimal places, that is, the last place fluctuates by one point, that is, 1 USD, and a * * * drops by 266 points, you earn 266 USD.
