Question

我在查找/理解正确的逻辑时遇到困难。

该指标应该向后看X条，画出一条有效蜡烛的开放线（即，上一个尺寸的两倍），并且当价格超过该线时，它应该更改颜色（并在其停止绘制被感动了

第一部分/第一循环（找到蜡烛并画线）到目前为止已正常工作。但是我迷失了如何/在哪里循环第二部分（检查价格是否越过线，改变颜色和/或停止画线）

我是否在一个循环中完成所有操作，还是需要使用两个循环？
如果有两个循环，它们必须分开还是嵌套？
在第二个循环中：我应该通过iOpen来获取开放行的价格，还是使用GetObject从行中获取价格？

任何帮助或正确方向的指针都将不胜感激。另外，请原谅我平庸的英语，因为它不是我的母语。

谢谢

编辑：我需要几行，每条有效蜡烛中的一行。这是我到目前为止的代码：

如何正确循环；画开线并在被击中后停止画图？
