在分支语句中执行有序列数据参与的函数，容易出现一些bar的序列数据不是你想象中的样子

老师这节课讲的很详细

https://video.tbquant.net/video?id=video443

（给我自己也找补一下 看了也容易忘）

我的意思是后续行情发展后，固定开仓当根bar的前5根K线的最低点止损，而不是跟随到当根K的前5根的低点，该怎么编写。

你把这个处理掉就可以了呀

在分支语句外面，每一个bar都计算一下这个值；

在开仓的时候，取到开仓时刻的这个值不就行了

        ProtectStopPrice = Lowest(Low[1],StopLength) * 0.99; 
        TrailStopPrice = Highest(High[1],StopLength) * 1.01;

        
        If(MarketPosition <> 1 And MAEFast[1]<MAESlow[1] and High >= Opint1)
        {
            Buy(PostionLots, Max(Open, Opint1));  
            MyEntryPrice = Max(Open, Opint1); 
            ProtectStopPrice_buy = ProtectStopPrice;  //这个变量类型为序列类型，止损用这个
            TrailStopPrice_buy = TrailStopPrice;
                  
        }
