Understanding Maker vs. Taker

Taker:

• When you place an order that trades immediately before going on the order book, either filling partially or fully, those trades will be "taker" trades.
• Trades from Market orders are always Takers, as Market orders can never go on the order book. These trades are "taking" volume off of the order book, and therefore called the "taker."
 

Maker:

• When you place an order that goes on the order book partially or fully, such as a limit order, any subsequent trades coming from that order will be as a “maker.”
• These orders add volume to the order book, helping to "make the market," and are therefore termed the "maker" for any subsequent trades.

Calculating Commissions for USDT-Margined Contracts

Formula:

Commission fee = Notional value * Fee rate
Notional value = Contract size * Execution price

For example, regular maker commission: 0.0100%; taker commission: 0.0200%

1. Buy 2 ETHUSDT contract using Market order:

Notional value = Contract size * Execution price
= 2 * 1,410 USDT
= 2,820 USDT
Taker commission fee: 2,820 * 0.0200% = 0.564 USDT
 

2. Sell 3 ETHUSDT contract using Limit order:.

Notional value = Contract size * Execution price
= 3 * 1,504 USDT
= 4,512 USDT
Maker commission fee: 4,512* 0.0100% = 0.4512 USDT
