An overnight fee, also known as a swap fee or rollover fee, refers to the cost or income incurred when you hold a trading position overnight (i.e., beyond the settlement time). Please note that the overnight fee on Wednesdays is charged at triple the normal rate. ### Trading-Related Questions 1.What time zone does TradFi trading use? Can it be changed? The default time zone is UTC+2 and cannot be changed manually.During daylight savings time (March to November), it automatically adjusts to UTC+3. 2.What leverage is available for TradFi trading? Can it be adjusted? Leverage varies by product and is preset for each instrument.At this time, leverage cannot be adjusted manually. 3.Are there margin requirements when trading TradFi products? Yes. As your position size increases, the initial margin requirement increases accordingly. 4.Why are my positions displayed separately? TradFi trading uses a hedging‑style position system, where each executed order appears as an individual position. This differs from crypto platforms that typically merge positions. 5.Does YUBIT support hedging in TradFi trading? Yes. You can hold both long and short positions on the same instrument simultaneously, allowing for more flexible and advanced trading strategies. **6. What is the 30% margin liquidation line, and how is it calculated?** In simple terms, the margin ratio measures how much of your **own capital** is included in your **total position value**. When this ratio falls to **30%**, the broker will forcibly liquidate the position to prevent losses from exceeding the borrowed funds. **Formula:**\ Margin Ratio = (Total Market Value of Position − Borrowed Amount) / Margin × 100% #### Liquidation Logic * **Warning Line:**\ When the margin ratio falls to **50%**, it means half of the margin has been lost. The system will send an email warning to the user. * **Liquidation Line:**\ When the margin ratio falls to **30%**, it indicates that your own funds have suffered severe losses and are only sufficient to cover 30% of the total position. **Example:**\ You use **$300** of your own funds and **$700** in borrowed funds to purchase stocks with a total value of **$1,000**.\ If the stock value falls below **$790**, your margin ratio drops below **30%**, and the position will be forcibly liquidated immediately. **7. Swap Fee (Overnight Holding Fee) Calculation** As TradFi contracts are not traded 24 hours a day and have market closure periods, a swap fee will be charged if you continue to hold a position during market closing hours. The swap fee is calculated based on the number of overnight days held and the applicable swap rate. Depending on the contract type, there are **three different calculation methods**: **1. Contracts with swap rates quoted in basis points** **Formula:**\ Swap Fee = Number of Lots × Contract Size × Price Precision × Swap Rate × Swap Multiplier **Example:**\ For a **Gas long position**, the swap rate is **-21.9 bps**.\ If the user holds **1 lot**, the contract size is **42,000**, and the minimum price precision is **0.0001**, then:\ Swap Fee = 1 × 42,000 × (-21.9) × 0.0001 = **-91.98** **2. Contracts with swap rates quoted in the settlement currency** **Formula:**\ Swap Fee = Number of Lots × Swap Rate × Swap Multiplier **Example:**\ For a **DJ30 long position**, the swap rate is **-10.4485**.\ Holding **2 lots for 3 days**:\ Swap Fee = 2 × (-10.4485) × 3 = **-62.691** **3. Contracts with swap rates quoted as a percentage** **Formula:**\ Swap Fee = Number of Lots × Contract Size × Counterparty Price × Swap Rate / 360 × Swap Multiplier **Example:**\ For **AAPL**, the swap rate is **-6%**.\ Holding **10 lots**, contract size **1**, counterparty price **351.44**:\ Swap Fee = 10 × 1 × 351.44 × (-6%) / 360 = **-0.5857** **8. What Is a 3-Day Swap?** In most financial markets (such as FX, commodities, and indices), trading does not take place over weekends. However, interest or financing costs for those two non-trading days must still be accounted for. A **“3-day swap”** refers to charging three days’ worth of interest on a single trading day to cover the weekend holding cost. To ensure clarity and transparency, positions are settled using a triple swap rate on a designated day each week. **How do we apply it?** 1. **Daily swap rate:**\ At the end of each trading day, positions are settled based on the applicable daily swap rate. 2. **3-day swap:**\ On the designated weekly settlement day (typically **Wednesday**, based on platform settlement time), the daily swap rate is multiplied by **three** to cover interest for **Saturday and Sunday**. 3. **Aligned with T+2 settlement convention:**\ Since most trades executed on Wednesday settle on Friday under T+2 rules, applying a 3-day swap on Wednesday ensures weekend interest is accurately accounted for. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
