写在前面：
开发这个工具的初衷，是基于在分析股票实践中想批量计算股票最近一次的上升振幅或下降振幅，视觉上，我们寻找波段低点和高点很容易，但如果用代码寻找波段低点与高点就颇为复杂，在实现代码过程中经常性快速验证代码得出的结果是否正确，这时如果能在K线上把计算出来的点直接标注出来就能一目了然。基于此，开发了这个工具辅助自己做视觉想法相关的代码设计，在我的理解，诸如波段的划分、股票是否在低位、股票是否在震荡这些都属于视觉感知的范畴，所以该工具就取名为“PyQt5开发验证K线视觉想法工具”。
V1.0版本，只做了单个验证里的点验证，即计算所得点在K线中进行标注
使用过程：
1 选择要验证的日数据文件（数据来自优矿）
2 选择与计算过程相同的时间区间
3 显示K线
4 输入并设置标记数据：点击该按钮后会弹出输入框，输入待标记的数据
1 输入标题：这个标题的作用是便于使用者区分多个标记
2 选择规则：当前V1.0版本只有“点””，选择规则后，在下一行会提示要输入的数据格式，输入的数据格式要和规则对应，否则会出错
3 选择点的形状
4 选择点的颜色
5 输入待标记的数据
6 点确定，左侧设置的结果将插入右侧的表格
7 点击提交，设置的结果将传入主界面

在主界面中点击“执行”，待标记的点将在K线图中标记出来，从上图可以看到，设置的两个点序列在K线图中标记出来了。文章来源地址https://www.toymoban.com/news/detail-610315.html
