Chapter 13: What Is Swap (Overnight Fees)?

If there’s one thing that catches new Forex traders by surprise, it’s checking their account balance on a Tuesday morning and noticing money vanished overnight. That isn’t a glitch; it’s the Swap Fee (also known as an overnight or rollover fee).

When you keep a Forex position open past the daily market close, your broker automatically charges—or pays—you an interest rate adjustment. But why does this happen?

1. The Secret Behind Swap Fees: Interest Rates

When you trade Forex, you aren’t just exchanging money; you are effectively borrowing one currency to buy another. Every country’s currency has an interest rate attached to it, set by their central bank. Because you’re holding borrowed money overnight, the broker has to settle the interest tab.

• Positive Swap (You Earn): If you bought a currency with a higher interest rate than the one you sold, the broker actually pays you for holding the trade overnight.
• Negative Swap (You Pay): If you bought a currency with a lower interest rate than the one you sold, you pay the broker for holding the trade.

2. The 5:00 PM EST Witching Hour

The Forex market is open 24 hours a day, but the official “trading day” ends at exactly 5:00 PM EST (New York time).

If you open and close a day trade before 5:00 PM EST, you will never pay a swap fee. But if you hold a position even one minute past 5:00 PM, the position is rolled over to the next trading day, and the swap fee is automatically deducted from (or added to) your account balance.

3. The “Triple Swap” Wednesday Rule

Here is a crucial rule that every trader learns the hard way: the 3-Day Swap applied on Wednesday nights.

Because the Forex spot market takes 2 business days to actually settle transactions, trades held past 5:00 PM EST on Wednesday roll over through the weekend (Saturday and Sunday, when banks are closed). To make up for the weekend, brokers charge three days’ worth of swap on Wednesday night.

4. How Swap Affects Different Trading Styles

Depending on your trading style, swaps might be completely irrelevant to you, or they might be your biggest expense.

5. Islamic (Swap-Free) Accounts

To accommodate traders who follow Islamic Sharia law—which prohibits earning or paying interest (Riba)—most brokers offer Swap-Free / Islamic Accounts. Instead of charging daily interest, brokers substitute the swap fee with a fixed administrative fee for positions held beyond a specific number of days.

6. How to Check Swap Rates in MetaTrader (MT4 & MT5)

You don’t have to guess what your swap fees will be. You can check the exact long and short swap rates for any currency pair directly within your MetaTrader platform before you open a trade.

Step-by-Step Instructions:

• Open Market Watch: Press Ctrl + M (or go to View $\rightarrow$ Market Watch).
• Find your pair, right-click it, and select Specification.
• Scroll down to find the Swap values.

Note: A negative number (e.g., -6.54) means the amount will be deducted from your balance, while a positive number (e.g., 1.20) means the amount will be credited to your account balance.
