HashKey Pro's trading fee is using maker/taker system.
Trades will be classified as “Taker” when an order you placed gets immediately traded (either partially or fully filled) before going on the order book. The Taker fee on HashKey Pro is 0.1%.
Trades will be classified as “Maker” when an order you placed does not get immediately traded, and gets placed partially or fully on the order book. The Maker fee on HashKey Pro is 0%.
When you place an order that gets partially matched immediately, you pay a taker fee for that portion(0.1%). The remainder of the order is placed on the order book and, when matched, is considered a maker order. The fee is 0% for that part of the total order.
