Dear LBank users:
The LBank contract transaction fee is
When you place an order that trades immediately, by filling partially or fully, before going on the order book, 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."
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.
Commission fee = notional value x fee rate
Notional value = number of contracts x trade price
For example, marker commission: 0.02%; taker commission: 0.060%
Buy 0.2 BTC BTCUSDT contract using Market order:
Notional value = number of contracts x opening price
= 0.2 BTC x 35,000
= 7,000 USDT
Taker commission fee is paid: 7,000 x 0.060% = 4.2 USDT
After the price rises, Sell 0.2 BTC BTCUSDT contract using Limit order:
Notional value = number of contracts x closing price
= 0.2 BTC x 40,000
= 8,000 USDT
Maker commission fee is paid: 8,000 x 0.02% = 1.6 USDT
