The SWAP is automatically applied at the close of the trading day for any positions kept open overnight.
According to the trading calendar, if multiple SWAP can be deducted or earned, this happens when the trading session does not start on the next day but in a few days.
For example, if the platform is closed on Saturday and Sunday, a triple swap is applied on Friday for Fri→Sat, Sat→Sun, and Sun→Mon.

When traders pay interest, effectively increasing the cost of holding positions open. Positive SWAP is deducted from the trader accounts according to the assets Margin Ratio.
