What is Overnight Fee in Forex? A Complete Guide for Cambodia Traders (2026)

What Exactly is an Overnight Fee?

In forex trading, every currency pair involves two currencies with different interest rates set by their respective central banks. When you hold a position overnight, your broker either pays you or charges you the difference between these two rates. This is called the swap or rollover rate. For Cambodia traders, this is especially relevant because many retail traders use USD-based accounts, and the most traded pairs involve the US dollar.

How Overnight Fees Work for Cambodia Traders

When you buy a currency pair (going long), you are essentially buying the base currency and selling the quote currency. If the base currency has a higher interest rate than the quote currency, you earn a positive swap. Conversely, if you sell a pair (going short), you earn a positive swap if the quote currency has a higher interest rate. The fee is automatically applied to your account balance at the rollover time. For example, if you hold a long position on AUD/USD and the Australian interest rate is higher than the US rate, you may receive a small credit each day. But if you hold USD/JPY long, and the US rate is lower than Japan's, you will pay a fee.

Why It Matters for Cambodia Traders

Cambodia traders often use smaller account sizes funded via local payment methods like Bank Transfer, Skrill, or USDT. Overnight fees can accumulate quickly, especially if you hold multiple positions or use leverage. For instance, a standard lot (100,000 units) on EUR/USD might incur a swap charge of around $5 to $10 per day depending on the broker. Over a week, that could be $35 to $70, which is significant for a $500 account. Therefore, understanding and managing overnight fees is essential for long-term profitability.

For Cambodia traders, the local trading context adds unique considerations. First, most retail forex brokers accept deposits via Bank Transfer, Skrill, and USDT. These payment methods are popular because they offer fast and low-cost transfers, but they do not affect swap rates. However, the choice of broker matters: some brokers offer swap-free Islamic accounts, which are ideal for Cambodia traders who want to avoid overnight fees entirely for religious or cost reasons. Second, the local financial authority in Cambodia does not regulate forex brokers directly, so traders must rely on international regulators like FCA, CySEC, or ASIC for protection. This means you should always check a broker's swap rate policy before opening a trade. Third, Cambodia traders often trade during Asian sessions, which means they may hold positions overnight more frequently than traders in other time zones. Finally, using USDT for deposits can sometimes offer lower spreads and swap rates, so it's worth comparing brokers that accept crypto funding.

1. Check Your Broker's Swap Rates
   Before opening a trade, log into your broker's platform and find the swap rates for the currency pair you want to trade. For Cambodia traders, this is often listed under 'Contract Specifications' or 'Instrument Details.'
2. Calculate Potential Costs
   Use the formula: (Contract Size × Swap Rate in Points) / 10. For example, if EUR/USD swap is -5 points for long positions and you trade 1 lot, the daily cost is -$5. Multiply by the number of days you plan to hold the trade.
3. Choose the Right Trading Strategy
   If you are a day trader, close all positions before 4:00 AM Cambodia time to avoid overnight fees. If you are a swing trader, consider pairs with positive swaps or use a swap-free account.
4. Monitor Your Account Regularly
   Overnight fees are applied automatically, so check your account history daily to ensure fees are correct. If you notice discrepancies, contact your broker's support team immediately.

For Cambodia traders, overnight fees are similar to the interest you pay on a margin loan from your broker. Both are costs of using leverage. However, overnight fees are specific to forex and are based on central bank rates, while margin interest is a flat fee charged by the broker. Understanding this distinction helps you choose the right broker and account type. For example, if you trade only major pairs like EUR/USD, overnight fees may be small, but for exotic pairs like USD/THB, they can be much higher due to larger interest rate differentials.

When you hold a forex position overnight, your broker automatically calculates the interest rate difference between the two currencies in the pair. For example, if you buy EUR/USD, you are buying the euro (which may have a higher interest rate) and selling the US dollar (which may have a lower rate). The broker pays you the difference. Conversely, if you sell EUR/USD, you pay the difference. This calculation is done at the rollover time, which is 5:00 PM New York time (4:00 AM Cambodia time). The fee is applied directly to your account balance in USD. For Cambodia traders, this means you can earn or lose money just by holding a position, independent of price movements.

Example 1: You buy 1 standard lot (100,000 units) of EUR/USD. The broker's swap rate for long EUR/USD is +3 points. This means you earn $3 per day. If you hold the position for 10 days, you earn $30 in swap credits.

Example 2: You sell 1 standard lot of USD/JPY. The swap rate for short USD/JPY is -5 points. You pay $5 per day. Over a week (7 days), that's $35 in fees. For a Cambodia trader with a $500 account, this is a significant cost.

Example 3: You use a swap-free account and hold a position for 30 days. No overnight fees are charged, saving you potentially hundreds of dollars compared to a standard account.

The local financial authority in Cambodia does not have specific regulations for forex trading or overnight fees. This means Cambodia traders are responsible for choosing regulated brokers from jurisdictions like the UK (FCA), Cyprus (CySEC), or Australia (ASIC). These regulators require brokers to disclose swap rates clearly and treat client funds fairly. For Cambodia traders, this regulatory gap means you must do your own due diligence. Avoid unregulated brokers that may manipulate swap rates or charge hidden fees. Always verify a broker's regulatory status before depositing funds via Bank Transfer, Skrill, or USDT.

• Use Swap-Free Accounts: Many brokers offer Islamic accounts with no overnight fees. Cambodia traders can request this even if not Muslim, as long as the broker allows it.
• Trade During Asian Session: To minimize overnight holds, focus on trading during the Asian session (8:00 AM to 4:00 PM Cambodia time) and close positions before rollover.
• Check Triple Swap Days: On Wednesdays, overnight fees are tripled to account for weekend rollovers. Avoid holding positions over Wednesday night if possible.
• Compare Brokers: Different brokers have different swap rates. Use CompareBroker.io to find brokers with competitive or positive swap rates for your preferred pairs.
• Use Limit Orders: Set take-profit and stop-loss orders to automatically close positions before rollover, reducing the risk of unexpected overnight fees.
