策略平仓--运行中是怎么理解？

// 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？
