All currency pairs provided by Doo Prime are based on the spread mode to calculate the overnight interest. The calculation formula is as follows:
- Swap Interest = Lot Size * Long or Short Swap Interest * Last Quote Point Value * Trading Days
Indirect bidding method:
For example, if you hold 1 lot of EUR/USD and hold the position overnight for one day, the formula for calculating the overnight interest is as follows:
- Lot size (1) * long overnight interest * (-3.52) * last tick value (1) * trading days (1) = -3.52
Direct bidding method:
For example, if you hold 1 lot of USD/CAD and hold the position overnight for one day, the formula for calculating the overnight interest is as follows:
- Lot size (1) * long overnight interest * (-2.50) * last quote point value (1) / USD/CAD exchange rate * (1.30000) * trading days (1) = -1.92
(*Note: The overnight interest data is updated at 19:00 Beijing time every day; due to real-time changes in the exchange rate against the US dollar, the displayed results are for reference only, and may differ from the actual interest charged)
