# Trading Settings and Operations

**Supported Coins and Leverage**

* **Mainstream contract coins:** such as BTC/USDT, ETH/USDT ChainBitX contract platform supports various mainstream digital asset perpetual contracts, currently covering popular coins including BTC, ETH, SOL, XRP, DOGE, all denominated in USDT. These coins have good market liquidity and attention, suitable for high-frequency or trend trading operations. In the future, ChainBitX will continue to expand supported coins based on user demand to meet diversified trading needs.
* **Leverage range: 1x - 125x** Users can freely select the desired leverage when opening positions, with a minimum of 1x and a maximum of 125x (depending on the specific coin). High leverage is suitable for short-term traders pursuing quick profits but also amplifies risk; low or no leverage suits more conservative strategies. New users are advised to start from lower leverage and gradually get familiar with contract volatility and risk control.
* **Supports 24-hour isolated/cross margin mode switching** ChainBitX contract accounts provide isolated and cross margin modes. Users can flexibly choose based on their trading strategy. In isolated mode, each position’s risk is managed independently, effectively avoiding linked losses; cross margin mode uses the entire account margin to resist floating losses and improves capital utilization. Both modes support manual switching anytime. The system will prompt possible impacts before switching, please operate cautiously.
* **Customizable dual position (hedging) function** The hedging function allows users to hold both long and short positions on the same coin simultaneously, enabling flexible operations under different market directions. This mechanism is especially suitable for quantitative trading, high-frequency trading users, or for implementing complex hedging strategies. Users can enable or disable this mode in contract settings. ChainBitX platform defaults to enabling hedging to support higher strategy flexibility.

**Minimum Order Amount and Maximum Position Size**

* **Minimum order amount:** about 10 USDT To lower the threshold for new users, ChainBitX contract platform supports a minimum small order size of 10 USDT. Even users with limited funds can trade real contracts and experience the real trading environment. The minimum order amount varies slightly by coin; users can check specific values on the order page. The system will automatically verify the input and provide prompts if the amount does not meet the minimum.
* **Maximum position size is automatically limited based on coin and account level** The system automatically sets the maximum position size according to user account level (e.g., regular user, VIP level) and each coin’s market volatility and risk factor. For example, highly volatile assets such as DOGE may limit the maximum single-account position to control systemic risk. If the user tries to exceed this limit when placing orders, the system will automatically block the order and display a “maximum position limit exceeded” message. With increasing account level and activity, the system will gradually raise the corresponding position limits.

**Margin Mechanism**

* Margin must be frozen for each position opened. The maintenance margin ratio is dynamically calculated after opening. Margin is the capital users must pay when opening positions and is an important mechanism set by the platform to control leverage risk. After opening, the system calculates the initial margin based on position size, leverage, and market price fluctuations, and sets a maintenance margin ratio (usually 0.5 to 1 times the initial margin). The maintenance margin ensures position safety. If account equity falls below this level, it will enter a risk warning state.
* If maintenance margin is insufficient, forced liquidation (bankruptcy) will be triggered. When rapid market fluctuations cause account equity to fall below the maintenance margin level, the system will automatically execute forced liquidation at the current market price to close risky positions, preventing larger losses or negative balances. ChainBitX platform has a bankruptcy line mechanism and real-time risk monitoring system. Once the risk level is too low, warnings will be sent via SMS, app pop-ups, emails, etc., reminding users to add margin or manually reduce positions in time to avoid forced liquidation.
