// 保护性止赢（激活并优化）

If(HighestAfterEntry[1] >= AvgEntryPrice*ProfitRatio_Stage1 And BarsSinceEntry>=1)//*1.01

{

   MyExitPrice = AvgEntryPrice*ProfitRatio_Stage2;//*1.002

   MyExitPrice = Max(MyExitPrice, Open);

   MyExitPrice = Max(MyExitPrice, MyExitPrice - MinPoint);

   If(Close <= MyExitPrice)

   {

       Sell(0, MyExitPrice);

       commentary("C,保护性止盈平仓");

       PlotString("zhushi","止盈平仓", Low , Green);

   }

}

MyExitPrice = Max(MyExitPrice, Open);这句策略运行中是怎么理解，对平仓有什么影响？
