The swap charged on your trade may be higher than the daily rate you expect due to how swaps are calculated and applied during overnight rollovers. This is normal trading behavior and not usually a technical issue.
Common reasons
1. Triple swap (rollover day)
Swaps are charged once per day when a position is held overnight. However, to account for the weekend when markets are closed, three days’ worth of swap is applied on one specific day of the week.
For Forex instruments, this usually occurs on Wednesday night
For other instruments, the triple swap day may differ
As a result, the swap charged on that day will be higher than a single daily rate.
2. You held the trade for multiple days
If your position remained open for more than one day, a swap is applied for each overnight rollover.
This means the total swap charged will be higher than one daily swap amount.
3. Swap rates can change
Swap rates are variable and may change due to:
Market conditions
Interest rate changes
Liquidity provider adjustments
The swap applied to your trade is based on the rate at the time of rollover, which may differ from previously seen rates.
