问题描述
我正在尝试使用以下代码在交易视图图表中绘制通道。它可以很好地作为基本需求，但是，我需要即兴创作，我无法找到编写代码的逻辑。需要你的帮助..

上述脚本首先确定了 3 个要点。如果要为上升趋势绘制通道，则需要第一个低点和下一个高点，最后是更高的低点。反之，下降趋势需要高点、低点和低点。
基于这些点，通道被绘制在图表上。在任何时候，我都只需要一个频道就可以显示在图表上。
目前的问题是：
-
假设它最初找到了这 3 个点以实现上升趋势。在 几根蜡烛，如果发现新高，它会重新调整蜡烛 删除旧的。你能帮我提出一个条件，要么 零线被打破或价格（高）已达到“fb4”没有新的渠道 应该绘制？
-
在通道下降且价格在范围内时发现上升趋势 零线和 fb4 线。目前，它删除下行通道 并绘制了一个新的上升通道。你能帮我提出一个条件吗 零线被打破或价格（高）已达到“fb4”没有 应该绘制新频道吗？
