Trades settle in two business days in the spot Forex market. If you sell 10,000 Euros on Tuesday, you must deliver 10,000 Euros on Thursday, unless the position is held open and rolled over to the next day. As a service to our traders, we automatically roll over all open positions to the next settlement date at 5:00pm EST. Rollover involves exchanging the expiring position for a position expiring the following settlement date. The positions being exchanged are not valued at the same price. If a trader is long the currency bearing the higher interest rate, the position being "sold" is worth more than the position being acquired. The reverse is also true; if a trader is short the currency bearing the higher interest rate, the trader is acquiring a position worth more than the one being "sold". The amount of the difference varies based on the currency pair, the interest rate differential between the two currencies, and fluctuates day to day.
At 5:00pm ET each day, funds are subtracted from or added to accounts with open positions because of this automatic roll over.
