if语句里面不能交易多个品种吗？

if(data0.open>2625 and data0.open<2675 and count<10 and time<0.15 and (data1.Q_AskPrice+data1.Q_BidPrice+data2.Q_AskPrice+data2.Q_BidPrice)/4>(data1.Q_AvgPrice+data2.Q_AvgPrice)/2+ avgoffset) { data1.SellShort(1,data1.Q_AskPrice-0.2); data2.SellShort(1,data2.Q_AskPrice-0.2); count = count + 1; 只对data1开单了，data2没有发出委托。只能开单一个品种一次吗？不能连续对两个品种开单吗？
