Actually, it's not what you understand. You are wrong. According to your understanding, it should be "1 every hand drop 1 minute, that is, the loss 10 dollars". Under the leverage of 1 to 100, you can understand that each point is equal to 1% of your deposit, but it is only about equal to.

Margin trading is generally in US dollars. For example, if you make more pounds against the US dollar, you have 1 ,000 US dollars, and the leverage ratio is 1: 1 ,000. Then you can use 100000 dollars to operate, and do more when GBPUSD 1.4000, that is, you divide 100000 dollars by 1.4, which becomes 7 1429 pounds, and it rises to/kloc in GBPUSD. So your 7 1429 pounds multiplied by 1.5 equals 107 143 dollars, and143 dollars minus 100000 dollars equals 7/kloc-. You earned 1000 points from 1.4000 to 1.5000, which is about 10 times or 7. 143 times according to the meaning in the first paragraph.

Short position: For example, if you have 10000 USD in your account and you only operate 1000 USD, then this 1000 USD will not disappear. When you lose it, the remaining $9,000 will disappear. $9000 is nine times as much as 1000, which means you can bear 900% of the loss. When the loss reaches 90 1%, you will automatically close your position, leaving only 1000 USD in your account.

Then we have to deduct the handling fee and add the remaining $980. And if the minimum unit of your system operation is 1000 dollars, then 980 dollars can't be operated, and at least 20 dollars can be added to operate. No one will ask you for debts!

I won't answer the third question, in dollars. No matter what the cross exchange rate is, it can be calculated by the method of the above example. Going long is the opposite of shorting.
