[Tutorial]- Trading Fee

Trading fee = trading volume × Rate
Trading volume = futures amount × face value × transaction price

-Example:
users are charged 0.03% for limit orders and 0.05% for market orders.
Let's assume that you have open 1,000 cont of BTCUSDT using a market order, and that the opening transaction price is 10,104 USDT.
Trading volume = 1000 cont × 0.001BTC/cont × 10,104 USDT = 10,104 USDT
Trading Fee = 10,104 USDT × 0.05% = 5.052 USDT

a. When the price rises, you sell these 1000 cont BTCUSDT  using a limit order and close the trade at 11,104 USDT.
Trading volume = 1000 cont × 0.001BTC per cont× 11,104 USDT = 11,104 USDT
Trading Fee = 11,104 USDT × 0.03% = 3.3312 USDT

How to calculate the trading fee of a currency-based contract?
-Trading fee = trading volume × Rate
-Trading volume = futures amount × face value / transaction price
Example:
users are charged 0.03% for limit orders and 0.05% for market orders.

Let's assumed that you have bought 10 BTCUSD perpetual futures contracts using a market order with an opening trade price of 10,104 USDT.

Trading volume = (10 cont × 100 USD) / 10,104 USDT = 0.09897 BTC
Trading Fee = 0.09897 BTC × 0.05% = 0.00004948 BTC
a. When the price rises, you sell these 10 BTCUSD perpetual contracts using a limit order and close the trade at 11,104 USDT.
Trading volume = (10 x 100 USD) / 11,104 USDT = 0.09006 BTC
Trading Fee = 0.09006 BTC × 0.03% = 0.00002702 BTC
