tbq3工作区图层排序有问题

订阅代码如下，指数图层应该在主力合约日线之下 OnInit() { t_symbol = Left(Symbol,2) + text(startym) + Right(Symbol,6); SubscribeBar(Symbol,"d",begindate);//订阅主力合约日线 If(Left(Symbol,2)=="IM")//订阅对应指数日线 { SubscribeBar("000852.SSE","d",begindate); } Else If(Left(Symbol,2)=="IF") { SubscribeBar("000300.SSE","d",begindate); } SubscribeBar(t_symbol,"d",begindate);//访问设置月份的合约日线 BatchSubscribe(t_symbol,Frequency(),OSPrice,Step,begindate,"C"); } 请看截图，指数图层自动跑到最下面：
