[Risk Control Adjustment] Contract Position Value and Aggregate Position Limits

Dear Users,

To further improve risk management for contract trading and reduce the potential risks of high-leverage trading, SUNX will adjust its position value limit logic. Details are as follows.

1. Effective Date

October 26, 2025 (UTC+8)

Please review your positions and leverage settings in advance and plan your trading accordingly to avoid order failures caused by exceeding the limits.

2. Position Value Calculation

The following calculation applies to this risk control rule:

Position Value = Margin × Leverage

Position value differs from the margin invested. With the same margin, higher leverage results in a larger position value.

3. Updated Limits

4. Aggregate Position Limit Explained

“Aggregate position limit” refers to the cumulative value of positions held across all trading instruments, rather than only the positions in the instrument you intend to trade.

When opening a position, compare the account’s aggregate position value across all instruments against the limit applicable to the instrument being opened.

Example:

If a user currently holds a BTC position worth 3,000,000 USDT, this exceeds the 2,000,000 USDT aggregate position limit applicable to other trading instruments. The user will therefore be unable to open new positions in other trading instruments until the relevant position value is reduced to below 2,000,000 USDT.

5. User Reminders

1. Check the per-transaction limit: Before placing an order, confirm whether the proposed position value exceeds the applicable per-transaction limit.
2. Review aggregate positions: When holding multiple instruments, monitor the aggregate position value across all instruments. Do not assess available position capacity solely from holdings in one instrument.
3. Use leverage prudently: Choose leverage based on your financial circumstances and risk tolerance, and avoid excessive increases in position value and trading risk through high leverage.
4. Verify order status: If an order fails, check the limits and order messages first, then adjust your actions after identifying the cause.
5. Contact official channels: If you have questions about this adjustment, please contact the platform through in-app customer support or SUNX’s official communities.

6. Risk Notice

Contract trading involves substantial risk. Leverage amplifies both potential gains and losses. Position limits are risk management measures and do not guarantee protection against trading losses or forced liquidation.

Please continuously monitor account margin, position size, and risk indicators, and manage leverage and positions prudently.

Thank you for your understanding and support of SUNX.
