回复：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）

回复：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。

回复：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; }

回复：优秀

回复：这种方式的protectstopprice_buy 和Trailstopprice_buy就是用于止损、止盈的、针对开仓点位的数值了吗？

回复：你可以把这个数值plot或者print 或者 commentary输出一下直观的看看是不是你想要的东西series类型具有传递性，需要再复习下0基础课，就可以理解为什么在这里取值，后面就是固定的了
