**Choosing the Right Description:**

* **Context:** Consider the overall tone and focus of your blog.
* **Audience:** Who are you writing for? Beginners? Experienced traders?
* **Length:** WordPress often displays descriptions as snippets, so shorter summaries are usually better.
* **Keyword Emphasis:** Aim to include relevant keywords like “股票市場” (stock market), “技術分析” (technical analysis), and “趨勢” (trend).

I recommend using **Option 1 or 2** for most WordPress tag descriptions. They’re concise, informative, and accurately summarize the essence of Dow Theory. If your blog is geared towards more advanced traders, option 3 would also be excellent. Use Option 4 for quick and broad appeal.
