Because there are many spot trading products, different trading products and even different exchange fees are different. Then before calculating, we must first know: 1, what is the price difference; 2. What is commission? 3. How much is overnight rate (although it is small, it is added for the sake of accuracy); What are the first-hand specifications;
Example: An investor bought primary spot gold (specification: 100 ounce) at the price of 1200 USD/ounce on March 0. The platform commission is USD 50/lot, the spread is USD 0.5/ounce, and the overnight interest is USD 3/day. On March 3, the price rose to $65,438 +0.230 per ounce, and investors closed their positions. Then the calculation method of final actual profit and loss is as follows:
Floating gain and loss: (1230-1200) *1*100 = 3000 USD.
Expenses incurred: price difference: 0.5* 1* 100=50 USD; Commission: 50* 1=50 USD; Overnight interest: 2 days *3=6 dollars. * * * The cost is $65,438+006.
Actual profit and loss =3000- 106=2894 USD.
The above is a detailed calculation method. As long as you know the above points, you can use this method to calculate.
