模拟回测环境
请问通过exchange.GetAccount()获取的账户信息，Balance数值是如何计算的？
初始资金50000，100倍杠杆，开仓初始资金500%，保证金占用理论上应该是5%，可用usdt应该是初始资金95%，实际打印出来的数据是3937
发明者量化-小小梦 初始资金*开仓5倍 = 50000 * 5 = 250000 ，100杠杆，即保证金使用开仓规模的1/100 ， 即2500。 /upload/asset/16994bd40a7251614992.png /upload/asset/16a9bab6a99666979233.png ``` function main() { exchange.SetContractType("swap") exchange.SetMarginLevel(100) var acc = exchange.GetAccount() Log(acc) //下单 var t = exchange.GetTicker() exchange.SetDirection("buy") exchange.Buy(t.Sell + 1000, acc.Balance * 5 / t.Last) Log(exchange.GetAccount()) } ``` Balance是当前可用保证金。偏差考虑资金费率因素。
XiaoHuihui0111 好的，蟹蟹
发明者量化-小小梦 平仓才有。
XiaoHuihui0111 我的意思是赚钱了，可用保证金应该是放大的，被扣除的资金费率不可能超过盈利数据
发明者量化-小小梦 币安期货有资金费率（回测也有），考虑下。

发明者量化-小小梦 这边测试正常的，您在具体看下。
XiaoHuihui0111 /upload/asset/20711b5b9230125975968.png 盈利越高，Balance数值越低
