现在我想用 10、21 EMA 等标记这些水平 EMA 线.我已经为标记的每日和每周收盘水平线添加了一个现成的代码，并尝试使用相同"为此编写代码，但似乎没有任何效果.我遵循了相同的程序，但我可能遗漏了一些重要的东西.
Now I want to label these horizontal EMA lines with 10, 21 EMA etc. I already added a ready code for Labeled Daily and weekly close horizontal lines and tried to use the "same" code for this, but nothing seems to work. I have followed the same procedure but I am probably missing something important.

推荐答案
您的代码运行良好.
我认为您在图表上向右滚动得不够远.
您已将默认 lblOffset 设置为 30，因此文本将向右移动 30 个小节.
请参阅下面根据您的代码制作的屏幕截图(未更改).
它清楚地在蓝线上显示文本Daily Close.
Your code works just fine.
I think that you're not scrolling far enough to the right on your chart.
You have the default lblOffset set at 30, so the text will be 30 bars to the right.
See below screenshot that was made from your code (unchanged).
It clearly shows the text Daily Close on the blue line.
更新代码以显示标签:
