Matriks IQ平台C#编译错误：OrderStatusEventArgs不是类型

我在Matriks IQ平台开发继承自MatriksAlgo的自定义交易算法时，重写OnOrderUpdate方法遇到编译错误："OrderStatusEventArgs is not a type"

已尝试的修复措施（均未解决） #

• 确认已正确导入所需命名空间（using Matriks.Trader.Core.Events; 和 using Matriks.Trader.Core.Orders;）；
• 查阅Matriks API文档确认OrderStatusEventArgs是否存在；
• 尝试使用ExecutionReportEventArgs、OrderEventArgs等替代事件参数类；
• 手动定义自定义OrderStatusEventArgs类，但引发冲突或异常行为。
