Swap

MetaTrader 5's Market Watch lists swap long and swap short, and several ways to calculate them: points, base currency, margin currency, deposit currency, or a percentage of the current or open price. The help page also shows that a broker can set a multiplier for each weekday. Its illustration uses a multiplier of 3 on Wednesday and 1 on other days. That is an example of the setting, not a rule that every symbol triples on Wednesday. The help page uses swap for the charge when a position is moved to the next trading day, including a swap that reopens the position. Stop-loss and take-profit levels stay in place across that OTC rollover. The rate is the broker's. This page does not say whether the charge will be a credit or a debit.
