The specific algorithm used to calculate the interest on an open trade in XXX/YYY is as follows:

#D1^rmUHrF for a long position:
L:e9w gY6^!~$H calculate the borrowing interest on XXX for the duration in question and convert it to USD 2l_N*F#rH!w
calculate the lending interest on YYY for the duration in question and convert it to USD

7W'A*e&N6B The platform credits or debits interest on the account (with an appropriate transaction) for trade that is open at 4pm, calculated for the time interval starting at 4pm the previous day or the time the trade was made, whichever is later, and ending at 4pm. When a trade is closed, the platform credits or debits interest on the account for the trade, calculated for the time interval starting at the previous 4pm or the time the trade was opened, whichever is later, and ending at the time the trade is closed. .t?K'P!?Qg%@W

Now assume that the trade is closed at 5:45am later the same day on Jan 1, 2001. The amount of time the trade is held open is 20580 seconds (= 12:01am - 5:45am), or 0.00065214 years (20580 secs / 31557600 secs --- there are 31,557,600 seconds in a year).

Calculate interest charged in JPY:
HT\/d tkLlM9L"H For calculating the interest charged on our JPY position, we first note that we effectively are short 1000 Euros worth of Japanese Yen, which, with the exchange rate of 91.7308 is 91730.8 units of JPY (= 1000 * 91.7308) on which interest is charged. We then use the following formula similar to the one used above: (Jb2zcgmq

Rso/gf Note that in this case the customer is collecting significantly more money than they are paying, due solely to the discrepancy in interest rates between the base and the quote currencies. In this instance, the base currency (EUR) interest rate is higher than the quote (JPY) interest rate, which is referred to as a "discount" quotation.
