If(HighestAfterEntry[1] >= MyEntryPrice + TrailingStart2*MinPoint) 
        {
            If(Low <= HighestAfterEntry[1] - TrailingStop2*MinPoint)
            {
                MyExitPrice = HighestAfterEntry[1] - TrailingStop2*MinPoint;// 如果该Bar开盘价即跳空触发，则用开盘价代替      
                If(Open < MyExitPrice) MyExitPrice = Open; 
                Sell(0,MyExitPrice);
            }
        }

这语句会不会信号闪烁呀？low的价格在变化的，那是不是满足后又不满足了呢？
