The overnight swap or financing rate is an interest rate credited or debited to the trading account in order to hold a trading position overnight.
The swap overnight is applied once per day during rollover time.
The financing rates are different for each trading instrument and the amount differs between long (buy) and short (sell) legs.
As swap values are updated on a daily basis, the best way to check them is to look at the symbol specification within the MT4 platform; just right click on each instrument and select “specifications” on the drop down menu.
We highly recommend to those not familiar with this subject to carefully study it before starting to trade on a real account.
