This means by rolling over the position, this at the same time closes the existing positions at the daily close rate and again coming into a new opening rate at the next trading day.

Rollover interest is the net effect of the money borrowed by an investor to purchase another currency and such interest is paid on the borrowed currency and earned on the purchased currency. To calculate this interest, you should get the short-term interest rates on both currencies, the existing exchange rate of the currency pair and the number of the currency pair purchased. For instance, an investor possesses 15,000 CAD/USD. The present rate is 0.9155, the short term interest rate on the Canadian dollar (base currency) is 4.50% plus the short term interest on the US dollar (quoted currency) is 3.75%, so the interest would be \$33.66 [{15,000 x (4.50% - 3.75%)} / (365 x 0.9155)].

If on the contrary, the short term interest rate on the base currency is lower than the short term interest rate of the borrowed currency, the interest rate would result into a negative number which may reduce the value of the investor’s account. Such interest can be avoided by taking a closed position on the currency pair. If an option is about to expire is quite favorable to grip, you can either buy or sell the later expiring option.
