In CFD trading, holding a position overnight will incur overnight funding charges, which are costs or benefits determined by the difference in interest rates implicit in the underlying asset. The design principle of the Wmax platform is that financing fees should not be hidden costs, but rather mechanistic arrangements that are calculable, traceable, and verifiable. This article explains its calculation logic, data sources and timing rules to help users understand "where does this fee come from?"

The nature of financing charges: the interest rate difference between long and short positions

The overnight financing fee is not a handling fee charged by the platform, but reflects the cost difference in capital occupation between long and short positions. Taking currency pairs as an example, a long position of buying a currency with a high interest rate and selling a currency with a low interest rate usually obtains positive financing; otherwise, a fee is paid. This mechanism is derived from interbank lending rates in the global interbank market (such as SOFR, €STR) and is reflected through swap points.

Wmax does not set a fixed rate, but dynamically calculates it based on a third-party authoritative interest rate source. The financing formula for each variety is disclosed on the product information page, for example:

Long Swap = contract size × (quote currency interest rate – base currency interest rate + platform adjustment factor) ÷ 365

The "Platform Adjustment Factor" is used to cover liquidation and operating costs. The value is constant and disclosed in advance. Fees are not a black box but a breakable formula.

Interest rate data source: independent, authoritative and verifiable

Wmax's overnight interest rate benchmark comes from internationally recognized financial data providers, including Bloomberg, Refinitiv and official interest rates released by various central banks. For example, the US dollar interest rate uses SOFR (Secured Overnight Financing Rate), and the euro uses €STR (Euro Short-term Rate), both updated and archived daily.

All original interest rate data are open for inquiry on the "Product Details - Financing Information" page, and users can view current and historical values. If the interest rate update is delayed due to holidays, the system will use the value from the previous trading day and a notification will pop up on the terminal. Transparency does not mean that the results are cheap, but that the source is credible and the process can be verified.

Billing time points and triple deduction rules

Overnight financing fees are settled uniformly at 21:00 UTC every day (22:00 during summer time), and are only charged to accounts that still hold positions at that time. The time point is selected based on the major global clearing cycles to ensure synchronization with liquidity providers.

It’s worth noting that holding a position overnight on Wednesday will result in triple fees. This is because the delivery day of standard foreign exchange transactions is T+2, and the position held on Wednesday actually spans three non-trading days on the weekend (Saturday, Sunday, and Monday), so three days of costs need to be paid in advance. Wmax clearly marked "Today's overnight stay will be charged 3 times Swap" on the order confirmation page and position panel to avoid user misjudgment. The rules do not change depending on whether the user knows it or not, but the platform has the responsibility to inform it in advance.

Display and settlement logic of positive and negative Swap

Some products (such as certain stock index CFDs or commodities) may experience positive financing during certain periods (that is, holding a long position will result in gains). This usually occurs when the underlying asset's implied yield is higher than the financing currency interest rate (such as a high dividend index). Wmax presents such situations truthfully and is not forced to convert to charges.

All Swaps, whether positive or negative, will be directly credited to the account balance in the form of cash, and "overnight financing" and the corresponding position ID will be marked in the "Fund Flow". Users can filter details by date and variety and check calculation results. Only when benefits and costs are equally transparent is true fairness.

How can users proactively manage financing costs?

Although Swap is determined by market mechanisms, users can plan reasonably in the following ways:

Check the historical Swap average of each variety on the "Product Information" page to evaluate the long-term holding costs; use a simulated account to test the accumulated costs under different holding periods; avoid opening new long-term positions before 21:00 on Wednesday, if you do not need to bear three times the cost.

Wmax does not encourage "frequent closing of positions to save Swap" because transaction costs may far exceed financing expenses. The prerequisite for rational management is to first clearly understand the cost structure.

Conclusion: Make every expense well-documented

Overnight financing fees are often misunderstood as "platform commissions", but in fact they are a natural reflection of the interest rate structure of the global financial market in CFD products. Wmax's choice is: not to hide, not to beautify, not to simplify, but to allow users to decide whether to accept the cost through public formulas, authoritative data and clear time points.

In the face of complex financial instruments, true user empowerment is not to waive fees, but to give the right to understand fees. Because only visible costs are worth taking seriously.
