The maximum leverage depends on the respective asset class:
5x leverage for BTC, ETH, and SOL
3x leverage for all other cryptocurrencies
The position size is always displayed as the total position value at the time of opening. Leverage is fixed and cannot be adjusted manually.
Example:
The price of BTC is 100,000 USDT.
You open a position of 1 BTC with 5x leverage.
Position value: 1 BTC × 100,000 USDT = 100,000 USDT
Required margin (at 5x leverage): 100,000 USDT ÷ 5 = 20,000 USDT
This means you control a position worth 100,000 USDT while only needing to provide 20,000 USDT as margin.
