请求合并EMA多时间帧表格与EMA Band指标并新增表格行
2026-7-21
合并多时间帧EMA表格与EMA Band指标，新增Band状态行
我有两段Pine Script代码：
- 一段是多时间帧200EMA数值表格指标：在表格中展示不同时间帧下的200EMA数值，单元格颜色随价格与EMA的关系变化
- 一段是可自定义参数的EMA Band指标：生成由两条EMA组成的通道，通道颜色根据价格趋势切换红绿
需求：在200EMA表格中新增一行，显示对应时间帧下EMA Band的颜色状态（绿色代表向上趋势，红色代表向下趋势）
实现步骤
要完成需求，需将两个指标的逻辑合并，并扩展表格功能：
- 整合EMA Band的核心逻辑：将原Band指标的输入参数、EMA计算、趋势判断逻辑移入表格指标中
- 获取多时间帧Band状态：使用
request.security函数，针对每个选定时间帧，获取该时间帧下EMA Band的趋势状态（价格同时在两条EMA上方为绿色趋势，同时在下方为红色趋势） - 扩展表格结构：将原表格的行数从2改为3，新增一行用于显示Band趋势状态
- 编写状态填充函数：新增函数处理Band状态单元格的颜色和文本显示，用直观的图标对应趋势状态
