如何只提取Zigzag指标提取的底部转折点？
比如说比较
double K = iCustom(Symbol(),0,"zigzag",ExtDepth,ExtDeviation,ExtBackstep,0,i); if (K==Low[i] && K>0) //..low zigzag......
deVries,
非常感谢你的及时答复。你的意思是简单地将iCustom的最后第二个参数改为0？我以前也试过这样做。结果肯定不是我想要的。为了使我的问题更清楚，我展示了以下两个数字来说明我的问题....
.
图1：当我想只显示僵尸时，却显示了不需要的顶点!我想在我只想显示底部的时候过滤掉所有不需要的顶部。
FIg2.所需的顶部被显示出来，没有任何不需要的底部。这是我想要的结果。
所以我的问题是：是否有可能只显示底部的点而不显示A/B/C/D/E点？我希望我已经把问题说清楚了.....。
非常感谢您的及时回复....

可以只显示人字形的缓冲区
zigzag正在重新绘制
看看这个结果
这是我得出的结果。我还没有检查上面deVries的结果[他发帖时我正在做这个]。

很好， 在你的代码的帮助下，我来到了这个......。

这是给的结果
现在，底部和顶部都与 "之 "字形匹配。
deVries: 不错的ubzen，在你的代码的帮助下，我来到了这个......这就是结果
干得好，deVries。

你好，deVries。
非常感谢你的代码。如果我想知道最后一条之字形腿的斐波那契回撤线与前一条之字形腿相比有多远。如何做到这一点？
我想做的是像图片一样，但下面的代码，我试图没有使它...
谢谢。

尊敬的各位，如何修改代码以只显示人字形的底部？
