Option Order Loss Will Be Deducted from Account Margin Balance under Portfolio Margin Mode

To better serve options traders, maintain market stability, and prevent extreme or abnormal transaction prices, Gate will adjust the calculation of the Account Margin Balance under the Portfolio Margin Mode of the Unified Account on November 13, 2025. Specifically, the option order loss will be deducted from the original calculation basis (other modes under the Unified Account will not be affected).

For sell orders: Option Order Loss = Order Amount × max ((Mark Price – Order Price), 0). When the sell order price is lower than the mark price, an order loss occurs.
For buy orders: Option Order Loss = Order Amount × max ((Order Price – Mark Price), 0). When the buy order price is higher than the mark price, an order loss occurs.

Before adjustment: Total Account Margin Balance = Account Equity – Spot Order Loss
After adjustment: Total Account Margin Balance = Account Equity – Spot Order Loss – Option Order Loss

If you hold options orders that meet the above conditions, please monitor your account risk closely and consider canceling orders or adding margin in advance to avoid potential impact.
