These contracts are linked to underlying equity assets. During weekends and market holidays when the stock markets are closed, the trading mechanisms will be adjusted as follows: #### 1. Trading Hours & Market Status * 24/7 Trading: The perpetual market remains open 24/7, but price and volatility are significantly influenced by the status of the underlying stock market. * Market Status: The system determines the current status as "Market Open" or "Market Closed" in real-time, based on the official trading schedule of the relevant stock markets. #### 2. Special Rules During Weekends & Holidays **2.1 Order Types** To protect your assets from abnormal price fluctuations caused by low liquidity when the stock market is closed, the following rules apply: * Market Orders Rejected: The system will reject all Market Orders. * Limit Orders Only: Only Limit Orders are supported, and the limit price must fall within the designated price range. * Conditional Orders: All Conditional Orders (including Take Profit & Stop Loss (TP/SL), Conditional Limit Orders, and Conditional Market Orders) triggered during market closed period must follow the same rules: Market orders will be rejected, and Limit orders outside the price range will also be rejected. **2.2 Price Range & Mark Price** Price range Calculation: * Formula: Long price upper limit is Last Closing Index Price × (1 + 1 / Max Leverage of the pair); Short price lower limit is Last Closing Index Price × (1 - 1 / Max Leverage of the pair). * *Example: If the maximum leverage for a perp trading pair is 10x and the last closing Index Price is $100, buy limit orders cannot exceed $110 and sell limit orders cannot be below $90 during market closure.* Mark Price Adjustment: * During market closure, the Mark Price is also restricted within the price range. * Clamping Mechanism: The price change is limited to 0.5% every 3 seconds. #### 3. Risk Disclosure * Order Execution Risk: Orders placed or triggered during weekends or holidays may be rejected if they do not meet the criteria mentioned above. * Price Deviation Risk: During market status transitions or periods of extreme volatility, the contract price may temporarily deviate from the external spot price. * Liquidation Risk: If your margin is insufficient, you may face the risk of forced liquidation --- # Agent Instructions This documentation is published with GitBook.
