Trading Fee and Maintenance Margin Rate Explanation

Contract Size and Trading Fee

Contract Size : All perpetual contract trades are conducted in contracts. Each contract corresponds to a certain contract size of digital assets. For example, BTC is 0.001 BTC, ETH is 0.01 ETH.

Trading Fee : When users conduct trades, the platform will charge a certain transaction fee, which is denominated in USDT, regardless of whether it is opening or closing a position.

The maintenance margin rate is the minimum margin rate required to maintain the current position. When the margin rate is less than or equal to the maintenance margin rate + the liquidation fee rate, it will trigger forced liquidation.
