Category links
- Category Links
This article provides a comprehensive guide to understanding and utilizing category links within the MediaWiki platform. Category links are fundamental to the organization of information on wikis like Wikipedia, enabling users to easily navigate and discover related content. This guide will cover the basics of categories, how to add pages to categories, best practices for categorization, troubleshooting common issues, and advanced techniques for more effective categorization. While this document focuses on the technical aspects of category links within MediaWiki, we will draw analogies to organizing information in trading strategies for binary options, highlighting the importance of clear categorization for efficient analysis.
- What are Categories?
Categories are a system for grouping pages that share a common theme or topic. Think of them as folders in a file system, but designed for a collaborative, web-based environment. They allow users to browse content based on subjects, rather than relying solely on internal links within the text. A single page can belong to multiple categories, reflecting the multifaceted nature of information.
In the context of binary options trading, categorizing strategies is crucial. You might have categories for "Trend Following Strategies," "Range Trading Strategies," "Volatility Based Strategies," and "Indicator-Based Strategies." Each strategy then belongs to one or more of these categories, making it easier to find the right approach based on market conditions. Similarly, categorizing trading instruments (e.g., currency pairs, indices, commodities) is essential for focused analysis.
- How to Add a Page to a Category
Adding a page to a category is remarkably simple. You use a special syntax within the page's wikitext. The syntax is as follows:
```wiki ```
Replace "CategoryName" with the actual name of the category you want to add the page to. For example, to add a page about "Apple Inc." to the "Companies" category, you would add the following line to the page's wikitext:
```wiki ```
Pages are automatically added to categories. There is no manual process beyond adding the category link. The category will appear at the bottom of the page, typically below the navigation boxes and other metadata.
- Subcategories
Categories can be nested within each other, creating a hierarchical structure. This is achieved using subcategories. To add a page to a subcategory, you need to specify the full path to the subcategory. For example, if you have a category "Fruit" and a subcategory "Citrus Fruits" within "Fruit," you would add a page about oranges like this:
```wiki ```
This signifies that the page belongs to both the "Citrus Fruits" category and, by extension, the "Fruit" category. This is analogous to analyzing a stock within a specific sector (e.g., Technology) which is itself part of a broader market index (e.g., S&P 500). The sector is a subcategory of the index.
- Best Practices for Categorization
Effective categorization is vital for the usability of a wiki. Here are some best practices to follow:
- **Be Specific:** Choose categories that accurately reflect the page's content. Avoid overly broad categories that would include irrelevant pages. For instance, instead of simply "Finance," use "Financial Markets" or "Investment Strategies."
- **Use Existing Categories:** Before creating a new category, check if an existing one already covers the topic. Consistency is key. In technical analysis, using standard indicators (like RSI, MACD, Moving Averages) is essential for consistent interpretation. Similarly, consistent categorization ensures clarity.
- **Consider Multiple Categories:** A page can belong to multiple categories if it covers multiple topics. Don't limit a page to a single category if it's relevant to others. A binary options strategy might fall into categories like "Short-Term Trading," "High-Risk Strategies," and "60-Second Strategies."
- **Avoid Over-Categorization:** Don't add a page to *every* remotely related category. This can clutter the category pages and make it harder to find relevant information.
- **Category Names:** Category names should be nouns or noun phrases. Avoid using verbs or descriptive phrases.
- **Redlinks & Category Creation:** If you use a category name that doesn't exist, it will appear as a red link. Clicking on the red link will allow you to create the category. Be mindful of creating unnecessary categories.
- Troubleshooting Common Issues
- **Page Not Appearing in Category:**
* **Syntax Error:** Double-check the category link syntax. Ensure you haven't made a typo or used incorrect formatting. * **Caching:** Sometimes, changes take time to propagate due to caching. Try purging the page's cache by editing the page and adding a comment (e.g., "Purge cache"). Saving the page will force a refresh. * **Category Itself Doesn't Exist:** Verify that the category you're trying to add the page to actually exists.
- **Page Appearing in Incorrect Category:**
* **Incorrect Category Link:** Review the category link on the page to ensure it points to the correct category. * **Subcategory Issues:** If you're using subcategories, double-check the full path to the subcategory.
- Advanced Categorization Techniques
- **Hidden Categories:** Categories can be marked as "hidden," meaning they don't appear on the page itself. This is useful for maintenance categories or categories used for internal tracking. Hidden categories are prefixed with a colon: ``.
- **Sorting Keys:** You can control the order in which a page appears within a category by using a sorting key. The syntax is: ``. For example, `` would place the page about apples at the beginning of the "Fruits" category, as "Apple" comes before other fruit names alphabetically. This is similar to setting order of execution of trades in a trading algorithm.
- **Default Sort:** You can set a default sorting key for all pages within a category by adding `Template:Defaultsort:SortingKey` to the category page itself.
- **Category Trees:** Tools are available to visualize the category structure as a tree, making it easier to understand the relationships between categories. These are often provided by extensions to MediaWiki.
- **Using Templates for Categorization:** Templates can be used to automatically add pages to specific categories, especially when dealing with large numbers of similar pages. This is a powerful feature for maintaining consistency.
- Category Links and Binary Options – A Parallel
Just as well-categorized pages make information accessible on a wiki, well-categorized trading information is essential for successful binary options trading. Consider these parallels:
- **Categories as Trading Strategies:** Each category can represent a distinct trading strategy.
- **Subcategories as Strategy Variations:** Subcategories can represent variations of a strategy (e.g., "Trend Following - Moving Average Crossover," "Trend Following - MACD").
- **Pages as Individual Trades:** Each page can represent an individual trade, categorized by the strategy used, the asset traded, and the time frame.
- **Sorting Keys as Trade Performance:** Sorting keys can be used to sort trades within a category based on profitability or other performance metrics.
By meticulously categorizing your trading information, you can easily analyze the performance of different strategies, identify profitable patterns, and refine your approach over time. Think of it as building a knowledge base of your trading experiences, similar to how a wiki builds a knowledge base of information. Analyzing trading volume within each category can provide further insights.
