About Maintenace Amount
You can find the “Maintenance Amount” from the table below with the position value in USDT. For example, if the position of USDT-margined BTC/USDT Contract is 500,000 USDT, then the maintenance amount would be 1,300 USDT.
Maintenance Amount formula
= [ Floor of Position Bracket on Level n * difference between Maintenance Margin Rate on Level n and Maintenance Margin Rate on Level n-1) ] + Maintenance Amount on Level n-1
For example, the Maintenance Amount on Level 5
= 250,000 * (1% - 0.5%) + 50 USDT
= 1,300 USDT
Note:
- Under cross margin, same ticker/symbol, both long and short position share the same liquidation price except isolated mode
- If the liquidation price is less than 0, the UI display would be “--”
