What are the Margin Maintenance calculation if I still have open orders on pairs listed with leverage above 10x after December 5, 2025?  

Your Maintenance Margin will be calculated based on the maximum leverage available on the relevant contract. The Maintenance Margin % will also be adjusted to 2.5% of the total Position Size, even if your position leverage is still above 10x.

So, to avoid potential risks or disruptions in trading, you are advised to:

1. Double-check open positions, leverage, and Open Orders on affected contracts.
2. Adjust leverage up to a maximum of 10x.
3. Ensure Margin Ratios are displayed accurately.
