USDT Perpetual Contract Trading Fee Calculation
Every trade executed on Bityi incurs a trading fee.
1. Trading Fee Overview
At order placement, traders must reserve extra fees:
Taker (Market Order) Fee: 0.05%
Maker (Limit Order) Fee: 0.04%
The actual trading fee is charged only when the order is executed, based on the actual transaction price.
If an order is partially filled, the remaining reserved fee is refunded to the available balance.
Liquidity Provider vs. Liquidity Taker
Liquidity Provider (Maker): Order enters the order book, increasing market depth (e.g., limit orders).
Liquidity Taker (Taker): Order is executed immediately, consuming market depth (e.g., market orders).
Trading fees are positive, meaning traders must pay a fee.
