What is Forex Swap?

Swap, also known as the overnight fee, is part of the cost investors have to pay to the forex broker if they want to hold a position overnight. Or swap is the interest that you earn or pay when making overnight trades.

When trading forex, we will buy and sell currency pairs, and each currency will have a different interest rate. When holding a currency pair overnight, there will be an interest rate differential. If the buy rate is higher than the sell rate, investors will receive a rollover fee. Conversely, if the buy currency pair is lower than the sell currency pair, you must pay an overnight fee. This fee varies between brokers.

How to calculate overnight forex swap?

Brokers will calculate the swap when the US session is closed. Depending on each broker and depending on the leverage, there will be different swap levels. You can check this overnight rate on the broker’s website.

In addition, you can also test right away on MT4. Then you will apply the swap rate to calculate the swap fee for each order as follows:

Swap = (Exchange rate/one point) x Volume (lot) x swap value in points

If the swap result is positive, you will benefit from this swap. If the impact is negative, the broker will deduct money from your account.


When trading the EUR/USD currency pair, the swap for short positions is 0.01, and long positions are -0.45. If a trader makes a sale of a standard lot of the pair on Thursday and keeps the position open overnight, on Friday, the swap will be calculated as follows:

Swap = 100,000 x (0.01 x 0.0001 pips) = 0.10 USD.

That is, with this short position, we will receive a profit of 0.1 USD.

In case an investor buys one standard lot of EUR/USD on Thursday and closes his position on Tuesday, the swap cost is calculated as follows:

Swap = 100,000 x (-0.45 x 0.0001 pip) = – 4.5 USD per night.

According to the above data, we will lose 4.5 USD per night, and currently, the position is held for three nights, so we have to pay a total profit of -4.5 x 3 = – 13.5 USD.

Assuming the same position is closed next Thursday, one week will have seven days, five weekdays, and two weekends. The interest to be paid is 7 x -4.5= – 31.5 USD.

As a general rule of Weekend Swap, fees will always be charged for any position opened on Wednesday. Therefore. No weekend fee will be charged for buy orders from Thursday to Tuesday next week, so only three nights will be charged. But when you keep overnight on Wednesday, you will be charged the weekend fee. Therefore the swap will be charged for seven days.

Broker’s swap fee calculation time.

The standard swap fee calculation time will fall between 22:00 and 24:00. In addition, depending on each broker, there will be separate time frames. Investors can find out this information by reading the broker’s regulations or asking the support staff.

For example, Broker A’s swap time is 22 hours. If you open a position at 21:59, the broker will charge overnight. But opening at 22:01, the broker will not charge overnight.
