After foreign exchange trading, if you can't close your position on the same day, you need to calculate interest. Different currencies have different interest rates, and buying and selling also needs to calculate interest. The interest rate standard mainly depends on the interest difference between currencies. Currency with high interest rate can often earn interest, while currency with low interest rate needs to pay interest.

Calculation method:

For example, in August 1 buy 2 lots of pounds, and in August 3 1 sell 2 lots of pounds to close the position.

Buying price: 1.8750 Selling price: 1.895438+06 Interest rate: 0.25%.

Calculation method of interest: (1.8750 х 2x10000x7.8x 0.25%)-360 х 30 days.

Interest = HK$ 609.37

Total profit = HK$ 65,438+03,990.74+HK$ 609.37.

Total profit = HK$ 65438 +04600.438+0 1.

Interest = (purchase price х number of lots х contract unit х7.8 USD х interest rate receivable or payable) х 360 х
