In the spot Forex market, rollover is required because all trades must be settled in two business days. In accordance with international banking practices, CMS automatically rolls over all open positions for settlement to the next date at 5 pm EST. Rollover involves exchanging the current position for a position expiring the following settlement date. For example, for traders who execute on Monday, the value date is Wednesday. An exception occurs when a position is opened and held overnight on Wednesday; the normal value date would be Saturday, but because banks are closed on Saturday, the value date is actually the following Monday. Due to the weekend, positions held overnight on Wednesday incur or earn an extra two days of interest. Trades with a value date that fall on a holiday also incur or earn additional interest.
