如何获得先前蜡烛的高低？
如何获得先前蜡烛的高低？
提问于 2022-08-10 07:36:41
我正在做一个指示器，显示摆动的低点和高度(3小节图案，其中秋千高的两边有较低的蜡烛，而摆动的低的是两边的更高的蜡烛)
我做到了，但我想提醒一下什么时候它被破坏了。正如您从代码中看到的，实际的高低是在swing形成之后生成的。我通过添加(偏移量-2)正确地显示swing。但警报触发在实际摆动高/低。
问:如何获得第二支先前的蜡烛高/低？

有趣的项目！
我不知道你到底在找什么，但我想我已经能够绘制出上一个秋千高点的峰值(或前一个秋千低点的低谷)。我给它画了一个步骤行，你应该可以用它来触发你的警报。
我添加了文字和符号，每当以前的分形被破坏时就会触发，这样我就能看到发生了什么。你会发现我也改变了几个变量的名字和东西。
如果密码有用的话请告诉我。
