What Happens During Forex Rollover and How Does it Affect Your Trades?

Nov 15, 2026

Forex rollover is a critical process in currency trading that occurs at the end of each trading day. It refers to the interest adjustment made for holding open positions overnight. This adjustment, known as a swap, reflects the interest rate differential between the two currencies in a pair.

Understanding Forex Rollover and Swap

When you keep a Forex position open past a certain daily cut-off time, it is automatically rolled over to the next trading day. This isn't just a technical extension of your trade; it involves a financial adjustment called a swap. Swap rates are either credited to or debited from your trading account, depending on the currency pair, the direction of your trade (buy or sell), and the interest rate policies of the respective central banks.

The calculation of swap rates is based on the overnight interest rate differential between the two currencies in a pair. If you hold a currency with a higher interest rate and sell a currency with a lower interest rate, you might receive a positive swap (credit). Conversely, if you hold a currency with a lower interest rate and sell a currency with a higher interest rate, you will likely pay a negative swap (debit). Swap rates can be positive or negative depending on market conditions, the instrument, and the volume of the open position.

When Does Rollover Occur?

The rollover of open positions typically occurs between 23:55 and 00:10 according to MetaTrader (MT) time. During this brief period, trading might be temporarily unavailable due to technical features of the MetaTrader terminal. This is a standard practice across the Forex market.

It's also important to note that liquidity in the Forex market can drop significantly during bank rollover times, which often coincide with the daily rollover period. This temporary reduction in liquidity can sometimes lead to wider spreads or quick price changes.

The Triple Swap Rule

To account for weekend interest, a triple swap amount is typically charged or credited for positions carried over on a specific day. For most Forex instruments, this triple swap occurs for positions held from Wednesday to Thursday. This is because the settlement for trades executed on Wednesday would normally be Friday, and carrying the position over the weekend (Saturday and Sunday) requires three days' worth of interest adjustment. However, there are exceptions:

  • Most Instruments: Triple swap charged from Wednesday to Thursday rollover.
  • Indexes: Triple swap charged from Friday to Monday rollover.
  • Ruble Pairs: Triple swap charged from Thursday to Friday rollover.

Impact on Traders

For day traders who close all positions before the end of the trading day, rollover and swap charges are generally not a concern. However, for swing traders or those holding positions for multiple days or weeks, swap costs or credits can significantly impact overall profitability. A series of negative swaps can erode profits, while positive swaps can add to them.

To stay informed about the potential costs or benefits, traders should regularly check the current swap rates for the instruments they trade. These rates are usually accessible within the symbol settings of the trading terminal, such as MetaTrader 5.
