A_SendOrder发送平仓单失败

以下代码是我发送平仓订单的代码，A_SendOrder每次返回的都是false，而且委托列表里面也没有委托单，请问是什么原因造成平仓失败。 CloseLots = IIF(A_TodayBuyPosition(AccountIndex) > 0, A_TodayBuyPosition(AccountIndex), 0); If(CloseLots > 0 && A_SendOrder(Enum_Sell,Enum_ExitToday,CloseLots,Price,AccountIndex)) { PrintLog("**********平多仓，平仓仓位" + Text(CloseLots) + "**********"); Result = True; } CloseLots = IIF(A_BuyPosition(AccountIndex) > 0, A_BuyPosition(AccountIndex), 0); If(CloseLots > 0 && A_SendOrder(Enum_Sell,Enum_Exit,CloseLots,Price,AccountIndex)) { PrintLog("**********平多仓(昨仓)，平仓仓位" + Text(CloseLots) + "**********"); Result = True; } Else { PrintLog("卖出平仓，发送了" + Text(CloseLots) + "个委托单，关注后续成交情况"); ALert(SymbolName + "提示平多仓"); //ClosePosId = CreateTimer(5000,DateTimeAdd(CurrentTime(),1000),10); }
