Charge standard: eight ten thousandths of the transaction amount.

Time of collection: the handling fee is collected in two directions, that is, when opening and closing positions, both parties take eight ten thousandths or six ten thousandths respectively.

Calculation formula of transaction cost:

Handling fee = opening fee+closing fee

Opening fee = opening price × contract unit × number of positions × rate

Closing fee = closing price × contract unit × number of positions × rate
