Adjustment to margin calculation under Tight-Spread mode

We’re updating the margin calculation for fully hedged positions under Tight-Spread mode.

Starting Mar 14, 2026, 10AM UTC+8, fully hedged positions will be required to maintain margin on one leg of the position.

This update applies only to Tight-Spread mode. 0 Fee Mode already uses a one-leg margin mechanism and will not be affected.

Order execution quality, spreads, and liquidity conditions will remain unchanged. This update only affects how margin is calculated for fully hedged positions.

What will change

- All newly opened fully hedged positions will require margin on one leg.

- Existing fully hedged positions will be adjusted to require margin on one leg.

Risk reminder

- If you use hedged strategies, review your margin usage before the effective time.

- After the adjustment, insufficient margin may increase your margin ratio and trigger a margin call or liquidation.
