1. What is the maximum order size?
The maximum order amount is not a fixed value. It depends on the leverage you select and the current margin tier settings for the specific asset.
For each asset, there is a maximum allowable position notional value (mark price × position size) at different leverage levels. Generally, the higher the leverage, the lower the maximum notional value allowed, which in turn limits the maximum order size.
You can go to the trading chart page, click “Overview” and switch to the “Leverage & Margin” tab to check the maximum position notional value and margin tier requirements for the selected leverage.
2. What is the difference between Cross Margin and Isolated Margin?
Under Isolated Margin, the margin for each position is managed independently. When the margin equity of a position falls below the required maintenance margin, the position may be liquidated. The risk is therefore limited to the margin allocated to that particular position.
Under Cross Margin, the total assets in your Futures Account, excluding the margin allocated to isolated positions, can be shared as margin. Liquidation is triggered when the total account equity falls below the required maintenance margin.
3. Why was my position liquidated?
When the margin ratio (maintenance margin ÷ margin equity) exceeds 100%, the system will trigger forced liquidation to prevent losses from exceeding the available margin.
Margin equity changes in real time based on fluctuations in the market mark price. We recommend adding margin before the margin ratio approaches the liquidation threshold to reduce the risk of liquidation.
4. Does adjusting the leverage affect my existing position?
Adjusting the leverage does not change the notional value of an existing position. However, it directly affects the amount of margin required and the maintenance margin ratio for that position.
Higher leverage requires less initial margin, but the liquidation price may move closer to the current market price, resulting in a higher level of risk.
5. How are funding fees calculated and charged?
The funding fee mechanism helps keep the price of perpetual contracts aligned with the spot price of the underlying asset.
The funding fee is generally calculated as:
Position Notional Value × Funding Rate
For most assets, funding is settled every 8 hours. When the funding rate is positive, long positions pay funding fees to short positions. When the funding rate is negative, short positions pay funding fees to long positions.
You will only pay or receive a funding fee if you still hold the position at the funding settlement time.
6. What is the difference between Take Profit/Stop Loss orders and Conditional Orders?
Take Profit/Stop Loss (TP/SL) orders are basic risk management tools. Once the preset trigger price is reached, the system will close the position at market price. They are mainly used to lock in profits or limit losses.
Conditional Orders are more flexible and consist of two parts: a trigger condition and an execution order. The trigger condition can be based on the latest price or mark price, while the execution order can be either a limit order or a market order.
You can also enable “Reduce-Only”, which is useful for stop-loss strategies and helps prevent the order from opening a new position in the opposite direction.
7. Why can't my order be submitted or why was it rejected?
Common reasons include:
The order amount exceeds the maximum notional value allowed for the selected leverage level.
Insufficient available margin.
The order price exceeds the system's permitted price deviation range.
Temporary maintenance or insufficient liquidity for the asset.
We recommend checking the “Leverage & Margin” section under “Coin Overview” first, and then confirming that your account has sufficient available balance.
8. What is the difference between Futures Demo Trading and Live Futures Trading?
Futures Demo Trading provides a trading interface and market data similar to the live trading environment, but uses virtual funds and does not involve real profits or losses. It is suitable for familiarizing yourself with the order process, testing strategies, or learning how the liquidation mechanism works.
Live Futures Trading uses real funds, meaning that all profits and losses, trading fees, and funding fees will be reflected in your actual account.
