Forex Rollover: What It Is & How It Works for 2026

---

1. What Is Forex Rollover?

Forex rollover is the process of extending the settlement date of an open currency position to the next trading day. It involves automatically closing a position at the end of the trading day and reopening it at the new rate, with an interest adjustment (swap) applied to your account based on the interest rate differential between the two currencies in the pair.

Rollover is an essential concept for any trader who holds positions overnight. When you keep a forex position open past the daily cut‑off time (typically 5 PM EST), your broker automatically rolls it over to the next day’s value date. This process includes a financing adjustment — you either earn or pay interest depending on the interest rate differential between the two currencies.

Understanding rollover is crucial for managing trading costs, especially for longer‑term positions. Positive rollover can add to your profits, while negative rollover can eat into them. This guide will explain everything you need to know about forex rollover — from how it works to strategies for managing overnight fees.

Simple Definition

Rollover is the interest paid or earned for holding a forex position overnight. It is calculated based on the interest rate differential between the two currencies in the pair. If you buy a currency with a higher interest rate than the one you sell, you earn positive rollover. If the opposite is true, you pay negative rollover.

Why Rollover Exists — The T+2 Settlement Convention

Forex trades settle on a T+2 basis — two business days after the trade date. When you hold a position overnight, the original trade’s settlement date is extended to the next business day. The rollover adjusts for the interest rate differential between the two currencies during that extra day.

Without rollover, traders would have to physically settle every trade after two days, which is impractical for most retail traders. Rollover allows traders to hold positions indefinitely while accounting for the cost of money.

2. How Does Forex Rollover Work?

Understanding the mechanics of rollover is essential for managing your trading costs effectively. Here is a step‑by‑step explanation of how rollover works.

The Mechanics of Rollover

At the daily rollover time (typically 5 PM EST), your broker automatically performs the following steps:

1. Your open position is closed at the current spot price.
2. A new position is opened at the same price, with the value date moved forward by one business day.
3. An interest adjustment (swap) is applied to your account, reflecting the interest rate differential between the two currencies.

From the trader’s perspective, the position appears unchanged — the price and size remain the same. However, the rollover adjustment is credited or debited to your account balance.

The Two Components of Rollover

Rollover consists of two main components:

• Tom/Next Swap Points: The forward price adjustment that reflects the interest rate differential between the two currencies. This is based on the forward points quoted by the interbank market.
• Financing Interest: The actual interest cost or credit calculated from the swap points and the position size. This is what appears as a credit or debit on your account.

Your broker’s swap rate is typically the interbank swap rate plus a small markup, which is how brokers generate revenue from rollover.

3. Forex Rollover Time — When Does It Happen?

Knowing the exact rollover time is essential for managing your positions and avoiding unexpected swap charges. Here is everything you need to know about rollover timing.

Standard Rollover Time (5 PM EST)

The standard forex rollover time is 5:00 PM Eastern Time (EST/EDT). This is when the New York trading session ends and the global forex market transitions to the next trading day. Any position held open past this time is subject to rollover.

This time was chosen because 5 PM EST marks the official close of the trading day in the forex market. The interbank market uses this cut‑off to determine the next day’s value date.

Rollover Time in Different Time Zones

The table below shows the rollover time in different time zones around the world.

📌 Always check your broker’s server time, as it may differ from your local time. The rollover is applied at the broker’s server cut‑off time.

MetaTrader Server Time vs Broker Time

In MetaTrader (MT4/MT5), the rollover typically occurs at 00:00 server time, which is usually set to GMT+2 or GMT+3 depending on the broker and daylight saving time. This means the rollover may not align with 5 PM EST in your local time.

Tip: Always check your broker’s server time in the MT4/MT5 terminal (displayed in the top‑right corner) to know exactly when rollover will occur for your account.

4. How Are Rollover Rates Calculated?

Understanding how rollover rates are calculated helps you anticipate the cost or credit of holding positions overnight. Here is the formula and an example.

The Interest Rate Differential Formula

Rollover rates are calculated using the following formula:

Rollover = (Position Size × (Interest Rate Differential) × (Days)) / 365

• Position Size: The notional value of your trade (e.g., $100,000 for 1 standard lot).
• Interest Rate Differential: The difference between the interest rates of the two currencies in the pair.
• Days: Typically 1 day, except for triple swap days (Wednesday) where 3 days are charged.

The broker also adds a small markup to the interbank swap rate, which is how brokers earn revenue from rollover.

Example Calculation — Long EUR/USD

Scenario: You are long 1 standard lot (100,000 EUR) on EUR/USD. The current interest rates are:

• EUR (base currency): 2.50% (ECB rate)
• USD (quote currency): 3.75% (Fed rate)

The interest rate differential is 2.50% − 3.75% = −1.25%. Because you are buying the lower‑yielding currency (EUR) and selling the higher‑yielding currency (USD), you will pay negative rollover.

Calculation:

• Position Size: 100,000 EUR
• Differential: −1.25%
• Daily Rollover: (100,000 × −1.25%) / 365 = −$3.42 per day

This means you would pay approximately $3.42 per day to hold this position overnight. On Wednesday, you would pay three times this amount ($10.26) due to triple swap.

Note: Actual swap rates vary by broker. Always check your broker’s swap rates in the MT4/MT5 terminal before holding positions overnight.

5. Positive vs Negative Rollover

Rollover can be either positive or negative depending on the interest rate differential between the two currencies in your trade. The table below explains the key differences.

📌 Positive rollover can be a significant source of profit for carry traders, while negative rollover is a cost that should be factored into your trading strategy.

6. What Is Triple Swap?

Triple swap, also known as triple rollover, is when three days’ worth of rollover interest is charged on a single day. For forex, this typically happens on Wednesday to account for the weekend (Saturday and Sunday) when markets are closed but positions remain open.

Why Wednesday Is Triple Swap Day

Forex trades settle on a T+2 basis. When you hold a position past Wednesday’s rollover, the settlement date moves forward by three days (Wednesday → Thursday → Friday → Monday), covering the weekend. As a result, you are charged three days of rollover interest on Wednesday night.

Here is the sequence:

• Monday night: 1 day of rollover (Monday to Tuesday)
• Tuesday night: 1 day of rollover (Tuesday to Wednesday)
• Wednesday night: 3 days of rollover (Wednesday to Monday, covering weekend)
• Thursday night: 1 day of rollover (Thursday to Friday)
• Friday night: 1 day of rollover (Friday to Monday)

Triple Swap for Different Instruments

The triple swap day varies by instrument:

📌 Triple swap is an important consideration for traders who hold positions over the weekend. Always factor triple swap into your trading plan to avoid unexpected costs.

7. Forex Rollover and Carry Trade Strategy

A carry trade is a strategy where traders buy a currency with a high interest rate and sell a currency with a low interest rate, earning the positive rollover (interest differential) as a daily return. This strategy can generate consistent income from rollover, in addition to potential price appreciation.

How Carry Trade Works

The carry trade is based on the interest rate differential between two currencies. Traders borrow in a low‑yielding currency (the “funding” currency) and invest in a high‑yielding currency (the “target” currency). The profit comes from the daily rollover interest, which is credited to the trader’s account as long as the position is held.

For example, if the AUD interest rate is 4.10% and the USD interest rate is 3.75%, a trader can earn positive rollover by going long AUD/USD. The daily rollover credit adds to the trader’s profits, making the carry trade attractive for longer‑term positions.

Example of a Carry Trade

Scenario: You buy 1 standard lot (100,000 AUD) of AUD/USD. The interest rate differential is 4.10% (AUD) − 3.75% (USD) = 0.35%.

• Position Size: 100,000 AUD
• Differential: 0.35%
• Daily Rollover: (100,000 × 0.35%) / 365 ≈ $0.96 per day

This may not seem like much, but over a year, the cumulative rollover income can be significant, especially with larger position sizes or higher interest rate differentials. The carry trade is one of the oldest and most popular strategies in forex trading.

Risks: Carry trades are not risk‑free. If the target currency depreciates against the funding currency, the price loss can outweigh the rollover gains. Additionally, changes in interest rate expectations can cause rapid price movements.

8. How to Avoid or Minimise Rollover Fees

If you want to reduce or eliminate rollover fees, here are several strategies you can use.

Close Positions Before Rollover

The simplest way to avoid rollover fees is to close all positions before the daily rollover time (5 PM EST). By doing so, you avoid the swap charge entirely. This is a common practice for scalpers and day traders who do not hold positions overnight.

Use Swap‑Free Islamic Accounts

Many brokers offer swap‑free (Islamic) accounts that do not charge rollover interest. These accounts are designed for traders who follow Sharia law, but they are available to other traders as well. Instead of charging rollover, the broker may charge a flat administrative fee per trade.

Note: Swap‑free accounts may have restrictions or higher spreads, so it is important to check the terms before opening one.

Factor Rollover into Your Trading Strategy

If you cannot avoid rollover, factor it into your trading strategy. For example:

• Trade in the direction of positive rollover: Buy high‑yielding currencies and sell low‑yielding ones to earn positive swap.
• Use rollover as a filter: Avoid holding positions that incur high negative swap costs.
• Calculate the net cost: Before entering a trade, calculate the expected rollover cost and ensure it does not erode your potential profits.
