In contract trading, transaction fees are often the huge amount that is easiest to overlook.

Taking Binance as an example, the maker fee can be as high as 0.05% (five ten-thousandths). When using a principal of 1000 USDT with 100x leverage, the calculation for a single transaction fee is:

1000 USDT (principal) * 100 (leverage) * 0.0005 (rate) = 50 USDT/transaction

This means that just opening and closing a position once will consume 100 USDT in fees. However, through the rebate mechanism, traders can recover 30%-70% of the fee costs. Assuming a 70% rebate, the actual expense is only 15 USDT/transaction, allowing high-frequency traders to save 8500 USDT in fees with an average of 100 transactions per day. #返佣
