On the BCB Exchange contract trading platform, each transaction will incur certain fees. To help users better understand the fee calculation methods, we will provide detailed explanations of the fee composition and calculation methods.
Contract trading fees mainly include the following types:
In each contract transaction, users need to pay a certain percentage of trading fees. Trading fees are generally divided into the following two categories:
Charged when users provide liquidity by placing limit orders that are filled.
Charged when users consume liquidity by executing market orders.
When users trade contracts using leverage, leverage fees will be incurred. Leverage fees are typically calculated based on the borrowed amount and the duration of borrowing. Specific fee rates may vary according to market conditions.
During contract position holding, users may be affected by funding fees. Funding fees are typically calculated periodically (such as every 8 hours) and are determined by the contract's funding rate and the position direction (long or short).
Trading Fee = Transaction Amount × Fee Rate
Leverage Fee = Borrowed Amount × Leverage Fee Rate × Borrowing Days
Funding Fee = Position Amount × Funding Rate
Assume a user conducts 50x leveraged trading by purchasing BTC contracts with 100 USDT, and the contract's Taker fee is 0.1%, borrowed amount is 4,900 USDT, leverage fee rate is 0.02%, position amount is 5,000 USDT, and funding rate is 0.01%.
5,000 USDT × 0.1% = 5 USDT
4,900 USDT × 0.02% × Days = 0.98 USDT
5,000 USDT × 0.01% = 0.5 USDT
