First of all, you need to declare what currency pair it is, because the point values of currency pairs with direct price and indirect price are different. In the case of a standard contract, not every point represents 10 USD. You are talking about indirectly priced currency pairs.

Second, the lever has nothing to do with the integral value. In the first case you mentioned, no matter how much leverage you have, your profit is $970, and leverage is directly related to the use of margin.

Third, in the case of firm trading 1: 1, you can buy as many euros as you want. 10000 USD is impossible to buy the standard and contract base currency of 100000 USD. From the calculation point of view, we can calculate the factors that do not consider the handling fee: for example, Euro/USD, firm trading, long 1.2 180, 10000 USD to buy Euro, which can be converted into 82/kloc-0.18 Euro. After closing the position, you can sell the euro, which can be converted into 10082.5438+00 at the exchange rate of 82 10. 18, so the profit should be 82 dollars.

Although I don't know how to calculate your $84, it should be my situation above.
