Important Notice Regarding Adjustment of Contract Position Risk Control Limits

Dear Users,

To further optimize the risk control system of the platform's contract market and reduce potential risks for high-leverage users, SUNX Exchange will optimize and adjust the logic for contract position value limits.

I. Definition of Position Value

To facilitate user understanding of the risk limit standards, this adjustment clarifies the calculation formula for position value as:

Position Value = Margin × Leverage Multiplier

II. Adjustment Details

1. BTC and ETH Trading Pairs
   • Single Trade Position Value Upper Limit: 7,500,000 USDT
   • Total Position Limit: 75,000,000 USDT
2. Other Trading Pairs
   • Single Trade Position Value Upper Limit: 1,000,000 USDT
   • Total Position Limit: 2,000,000 USDT

III. Explanation Regarding Total Position Limit

The "Total Position Limit" refers to the cumulative upper limit of the value of positions held by a user across all trading pairs.

Example:
If a user currently holds a BTC position valued at 3,000,000 USDT, they will be unable to open new positions in other trading pairs until this value is reduced below 2,000,000 USDT.

IV. Effective Time

This optimization of the risk control logic will officially take effect on October 26, 2025 (UTC+8).
Please plan your positions and leverage ratios in advance to avoid order failures due to exceeding the limits.

SUNX Exchange consistently adheres to the operational philosophy of "User-First, Safety-First," continuously optimizing the risk control system to provide a safer and more stable trading environment for global users.
