Rollover refers to the process of holding a trading position from one trading day to the next. When this happens, the position is effectively carried over into the new trading day at the updated market rate.
The rollover process occurs automatically and may result in temporary price fluctuations or widened spreads on certain instruments.
In the forex market, which operates 24 hours a day, five days a week, rollover typically takes place at the end of the New York trading session (5:00 PM EST). On Wednesdays, rollover rates are tripled to account for the two days when the market is closed over the weekend. For indices, the triple rollover usually occurs on Fridays.
