针对标的1的计算过程：假设账户中有若干BTC本金 a：BTC/0.0008819 - (BTC/0.0008819)x0.001 = xBNB b：xBNB/0.00594 - (BNB/0.00594)x0.001 = yZIL c：yZILx0.00000525 - (ZILx0.00000525)x0.001 = zBTC

分子 换成 分母，就用quantity * price 分母 换成 分子，就用quantity / price

[zlq4863947]

决定因素	决定结果
买卖	分子还是分母
分子还是分母	乘法还是除法

推导出来: 卖-》分子换分母-》 quantity * price 买-》分母换分子-》 quantity / price

所以还是看买卖 卖-》quantity * price 买-》quantity / price
