Spread is a visible cost, but overnight interest is a bill that many people notice for the first time after holding positions overnight. It is charged on a daily basis, has different directions, and will double on specific dates. The rules are not complicated, but the pricing logic is worth understanding. This article explains what overnight interest is, how it is priced, why the long and short directions are different, and how long-term position holders manage it.

What is overnight interest?

Holding a position overnight will incur holding costs, which are essentially the time value of funds: if you hold long or short orders, it is equivalent to occupying the capital position required for the platform to match transactions. This part of the funds needs to be charged at a certain interest rate, which is reflected in the bill as overnight interest. It is not a fee set arbitrarily by the platform, but a cost of funds related to the market interest rate environment.

Pricing logic: follow the interest rate

The level of overnight interest is usually related to the base interest rate of the currency in which the transaction is denominated. When the interest rate level changes, the overnight interest rate will also be adjusted accordingly. This also explains why there are obvious differences in overnight interest rates between different periods and different varieties - it is not a fixed number, but a dynamic cost that fluctuates with market interest rates.

Long and Short Directions: Why They’re Different

Overnight interest is usually calculated and charged in two directions: long orders and short orders. It may be charged in one direction and paid in both directions, or it may be charged in both directions. The difference in direction comes from the different fund flows corresponding to the two positions. It is important for traders not to just look in one direction: before taking a long-term position, check the overnight interest rates of both long and short orders to know the true time cost of the position. At the same time, pay attention to confirm the interest calculation time point (many platforms use New York closing as the boundary). The interest calculation time point of different platforms may be different, which directly affects the determination of "overnight".

"Double" rule for specific days

Some platforms will charge multiple times of overnight interest on specific dates to cover the time cost during the suspension of trading on weekends. This means that if you hold a position over the weekend before or after the charge date, an overnight fee could be equivalent to three times the usual amount. Different platforms may have different definitions of collection days (some are treated as Wednesday or Thursday), which shall be subject to the platform's announcement. Short-term traders can avoid this window; long-term position holders must calculate this fee into their costs in advance.

How to manage overnight costs for long-term positions

The first is to incorporate cost calculations: Convert the number of days the position is held, daily overnight interest, and the daily multiple of collection into the expected cost, and then determine whether the transaction is cost-effective. The second is to compare the differences in directions: for the same product, the overnight fees for the long and short directions may be different. When judgment allows, choosing the direction with lower fees can reduce holding costs. The third is to pay attention to changes in interest rates: changes in market interest rates will be transmitted to overnight interest rates, and the cost structure of long-term positions will be re-evaluated when the interest rate cycle changes. The fourth is to use simulated trading to calculate: first use a simulated account to hold positions for a few days, observe the actual overnight bills, and be aware of it.

Calculate overnight costs clearly

Putting overnight costs on the platform, WMAX publicly announces the overnight interest information of various varieties, including long and short directions and charging rules. Traders can check this fee before opening a position; the simulation account is suitable for holding positions for a few days to observe the actual situation of overnight bills and form a reference before entering the real offer. It should be noted that the overnight interest rate changes with the market interest rate, and the platform announcement may be adjusted regularly. Traders should refer to the latest announcement. Whether WMAX is suitable for you depends on your holding period and sensitivity to time costs.

write at the end

Overnight interest is a time cost that long-term position holders cannot avoid: it follows the interest rate, calculates and collects in different directions, and doubles on a specific date. Only by understanding its pricing logic, and counting the long and short direction and collection date into costs can the cost account of long-term positions be considered complete. Regardless of whether you choose WMAX or other platforms, it is recommended to check the overnight rules before opening a position and always control the risk within an acceptable range. Leveraged trading carries high risks. Please fully understand the relevant rules before entering the market and make prudent decisions.
