怎么样在收盘前对未成交的平仓委托单进行撤单

请问：想要在收盘前做这个处理：1、对未成交的平仓委托单进行撤单。2、撤单后，按最新的即时价格重新报单。我的想法是在onorder里对每笔平仓单进行记录订单号，然后在onbar里根据时间条件进行撤单。但是编译显示onorder里的结构体ord没有声明，这样的话应该怎么改？或者是，有没有其它办法？谢谢。以下为代码：Params Numeric Length1(40); Numeric Length2(20);Vars Series<Numeric> Lots; Series<Numeric> HighestValue1; Series<Numeric> LowestValue1; Series<Numeric> HighestValue2; Series<Numeric> LowestValue2; Global Integer sellxinhao; Global Integer buytocoverxinhao; Global Integer c; Global Integer d; Series<Bool> Time_Close_day; Global array<Integer> orderIds; Bool c_ok; Bool d_ok; Events OnInit() { //与数据源有关 Range[0:DataCount-1] { //=========数据源相关设置============== AddDataFlag(Enum_Data_RolloverBackWard()); //设置后复权 AddDataFlag(Enum_Data_RolloverRealPrice()); //设置映射真实价格 AddDataFlag(Enum_Data_AutoSwapPosition()); //设置自动换仓 //AddDataFlag(Enum_Data_IgnoreSwapSignalCalc()); //设置忽略换仓信号计算 //******************获取映射主力合约****************// Array<String> symbols; Bool ret = GetOrderMapRelatedSymbols(symbols); //******************获取映射主力合约****************// } } OnOrder(OrderRef ord) { if(ord.symbol==RelativeSymbol and (ord.side==Enum_Sell or ord.side==Enum_ShortSelling) and (ord.combOffset==Enum_exit or ord.combOffset==Enum_ExitToday)) { c = ord.orderid; print(\"selltime:\"+text(time)); print(\"a:\"+text(c)); //t_id=CreateTimer(5000); //t_time=ord.createDateTime; } if(ord.symbol==RelativeSymbol and (ord.side==Enum_buy or ord.side==Enum_MarginBuying) and (ord.combOffset==Enum_exit or ord.combOffset==Enum_ExitToday)) { d = ord.orderid; print(\"butycovertime:\"+text(time)); print(\"a:\"+text(d)); //t_id=CreateTimer(5000); //t_time=ord.createDateTime; } } onBar(ArrayRef<Integer> indexs) { //集合竞价和小节休息的过滤； Numeric Lots=1; Time_Close_day=(Time>=0.1459 and Time <0.1500); //or (Time>=0.0055 and Time < 0.0100) ; //or (Time>=0.2250 and Time < 0.2300) If(Time_Close_day)//当前时间如果大于设置时间，进行清仓； { if(ord.symbol==RelativeSymbol and ord.status==Enum_declared and sellxinhao==1 and MarketPosition>0) { A_DeleteOrderEx(c); print(\"指定时间撤多单time:\"+text(time)); print(\"指定时间撤仓多单:\"+text(c)); c_ok=true; } if(c_ok) { sell(0,low); c_ok=false; } if(ord.symbol==RelativeSymbol and ord.status==Enum_declared and buytocoverxinhao==1 and MarketPosition<0) { A_DeleteOrderEx(d); print(\"指定时间撤空单time:\"+text(time)); print(\"指定时间撤空单:\"+text(d)); d_ok=true; } if(d_ok) { buytocover(0,high); d_ok=false; } } HighestValue1 = HighestFC(High, Length1); LowestValue1 = LowestFC(Low, Length1); HighestValue2 = HighestFC(High, Length2); LowestValue2 = LowestFC(Low, Length2); //开仓条件 if(H>=HighestValue1[1] and MarketPosition==0) { Buy(Lots,HighestValue1[1]-500); sellxinhao=0; } if(L<=LowestValue1[1] and MarketPosition==0) { SellShort(Lots,LowestValue1[1]+500); buytocoverxinhao=0; } // 平仓条件 If(MarketPosition >0 And BarsSinceEntry >0 And Low <= HighestValue2[1]) { Sell(0,Min(Open,HighestValue2[1])); sellxinhao=1; } // 持有空单时，自适应出场均线高于出场线，平空单 If(MarketPosition <0 And BarsSinceEntry >0 And High >= LowestValue1[1]) { BuyToCover(0,Max(Open,LowestValue2[1])); BuyToCoverxinhao=1; } }
