In foreign exchange trading (FX), a rollover is the action taking place at end of day, where all open positions with value date equals SPOT, will be rolled over to the next business day.
[3] Trading platforms offer rollovers but the process involves a rollover interest fee which is calculated according to the difference between the interest rates of the traded currencies.
Then, it is needed to divide the result by 365 times the base exchange rate.
[5] However, usually, the rollover is shown in the trading platform or on the broker's website, which frees the trader from unnecessary calculations.
Thus, to check the rollover, it is needed to find a swap (long and short) on the broker's website or in the trading platform.
