Closing price of the day * contract unit * lots * interest rate *( 1/360)= overnight interest.

However, it should be noted that the algorithm of overnight interest on spot gold may be different for different platforms. Generally speaking, the trading order of buying up and opening positions is similar to that of buying down and opening positions in overnight rate, and the overnight rate that investors need to pay per lot 1 day is actually not much different.

Investors should pay special attention to that when there are holidays, the calculation of overnight interest on spot gold will be postponed to the next trading day, that is to say, the interest-bearing days of overnight interest on spot gold will be accumulated. Therefore, everyone should pay attention to controlling their positions, and make decisive appearances at the right time to save more investment costs.
