Q1：股票做T成本是怎么计算的。

刚开始19.45买入200股，18.94又买入100股的成本价：(19.45×200+18.94×100)÷300=19.2819.96卖出100股赚了这么多：(19.96-19.28)×100=68现在这手中的200股的成本价是：（19.28×200-68）÷200=3788÷200=18.9418.08买入了300股之后，手中这500股的成本是：(18.08×300+3788)÷500=9212÷500=18.42421元卖出300挣了这么多：(21-18.424)×300=772.8现在手中200股的成本是：(18.424×200-772.8)÷200=2912÷200=14.5620.66买进300之后手中500股的成本价就是：(2912+20.66×300)÷500=9110÷500=18.22做T后最终的成本价是18.22元。
