I had perform a API trade using paper trade. After 1 month monitoring, i understand that there is a charge when i buy or sell the BTC/USD. The charge is applied to QTY. However, i had extract all the order performed and made an analyse. I found out I am supposed to lost only 13 usd but the paper trade show a lost of 32. Can you help to explain what is other charge that i miss out?
