Aster has implemented a profit-sharing model reduce the impact of fees on users. When the position is profitable, a fee range from 15% to 20% will be charged on the profits. When the position incurs a loss, no fees will be incurred.
For example, 15% fee will be charged on the profits when you place orders on BTCUSDT or ETHUSDT pairs.
In the meantime, users could select the flat fee ratio when opening the position. 0.03% will be charged base on the national value of the position.
