Template:Infobox is a core component of MediaWiki used to create standardized summary boxes, typically displayed in the upper-right corner of an article. These boxes, known as infoboxes, present essential information about the article's subject in a structured and easily digestible format. This article will guide beginners through understanding, creating, and utilizing infoboxes effectively.
An infobox is essentially a Template that defines a specific layout for presenting data. It's designed to quickly convey key facts, such as dates, locations, characteristics, or relevant statistics. Think of it as a snapshot of the most important information, allowing readers to grasp the core details without having to read the entire article.
Infoboxes are particularly useful for:
Biographies: Displaying birthdates, places of birth, occupations, and notable achievements.
Geographical Locations: Presenting coordinates, population, area, and other geographical data.
Organizations: Listing founding dates, headquarters locations, and types of organizations.
Scientific Concepts: Summarizing key properties, classifications, and discoveries.
Films/Books/Games: Displaying release dates, directors/authors, and genre information.
Why Use Infoboxes?
Consistency: Infoboxes promote a consistent look and feel across all articles on a wiki, making it easier for readers to find information. A standardized format is crucial for usability.
Readability: They present information in a clear and concise manner, improving readability and comprehension.
Quick Overview: Infoboxes provide a quick overview of the subject, allowing readers to quickly assess its relevance to their interests.
Data Retrieval: They facilitate data retrieval and analysis, as the information is structured in a predictable format. This is important for Semantic MediaWiki extensions.
Navigation: Infoboxes often contain links to related articles, improving navigation within the wiki.
Understanding the Syntax
Infoboxes are created using MediaWiki's template system. The basic syntax involves using the `{{Infobox` tag, followed by parameters that define the content and layout of the box. Let's break down the key elements:
`{{Infobox` : This opens the infobox template.
`title =` : Specifies the title of the infobox. This is the heading that appears at the top of the box.
`image =` : Specifies the filename of an image to be displayed in the infobox. Use the `File:ImageName.jpgwidth=px` format *within* the parameter value.
`caption =` : Provides a caption for the image.
`header =` : Defines a header for a section within the infobox. You can have multiple `header` parameters to create distinct sections.
`content =` : The main body of the infobox. This is where you'll enter the key information about the subject. You can use standard MediaWiki formatting (e.g., wikilinks, bold text, *italic text*) within the `content` parameter.
`label1 =` , `data1 =` , `label2 =` , `data2 =` , etc.: This is the most common way to define key-value pairs within an infobox. `label1` is the name of the data field (e.g., "Born"), and `data1` is the corresponding value (e.g., "January 1, 1990").
`}}` : This closes the infobox template.
A Simple Example
Let's create a simple infobox for a fictional character named "Alex Johnson":
This code will generate an infobox with the title "Alex Johnson", an image, and two sections: "Personal Information" and "Skills". The "Personal Information" section will display the birthdate, occupation, and nationality, while the "Skills" section will provide a brief description of the character's abilities.
Technical analysis often relies on quickly digestible data, making infoboxes ideal for summarizing key statistical information about assets. For example, an infobox for a stock could include data on its Price-to-Earnings ratio, Dividend Yield, and Beta.
Creating More Complex Infoboxes
Infoboxes can become much more complex, with multiple sections, images, and data points. Here are some advanced techniques:
Using Parameters for Reusability: Instead of hardcoding all the data directly into the infobox, you can define parameters for each piece of information. This makes the infobox more reusable and easier to update.
Conditional Statements: You can use conditional statements (e.g., `#if:`, `#switch:`) to display different information based on the value of a parameter. This allows you to create infoboxes that adapt to different types of subjects.
Templates Within Templates: You can nest templates within infoboxes to create even more complex layouts and functionality.
Using Classes for Styling: You can apply CSS classes to different elements of the infobox to customize its appearance.
Using Existing Infobox Templates
Before creating a new infobox from scratch, it's always a good idea to check if an existing template already meets your needs. Many wikis have a library of pre-built infoboxes for common topics.
To find existing infobox templates:
1. Search the Template Namespace: Go to the `Template:` namespace (e.g., `Template:Infobox Person`, `Template:Infobox Country`). You can use the search function to find templates related to your topic.
2. Browse Category:Templates: Many wikis categorize templates. Look for categories like `Category:Templates` or `Category:Infobox Templates`.
3. Check the Wiki's Documentation: The wiki's documentation may list available infobox templates and provide instructions on how to use them.
Once you find a suitable template, simply copy and paste it into your article and replace the placeholder values with the appropriate information.
Consider the following when choosing an existing infobox:
Relevance: Does the template contain the data fields you need?
Consistency: Is the template used consistently across other articles on the wiki?
Maintainability: Is the template well-maintained and updated?
Customizing Existing Infoboxes
Sometimes, an existing infobox may not perfectly meet your needs. In this case, you can customize it by:
Adding New Parameters: You can add new parameters to the template to display additional information.
Modifying Existing Parameters: You can change the labels or data types of existing parameters.
Changing the Layout: You can adjust the layout of the infobox by rearranging the parameters or adding new sections.
However, be careful when customizing existing infoboxes, especially if they are widely used. Changes to a widely used template can affect many articles on the wiki. It's generally best to create a new template if you need to make significant changes.
Best Practices
Keep it Concise: Infoboxes should be concise and to the point. Avoid including excessive detail.
Use Standardized Labels: Use standardized labels for data fields to ensure consistency across articles.
Provide Sources: Whenever possible, cite sources for the information presented in the infobox.
Use Appropriate Images: Choose images that are relevant to the subject and of high quality.
Test Your Infobox: Before saving your article, preview the infobox to ensure it displays correctly.
Follow Wiki Guidelines: Adhere to the specific infobox guidelines established by your wiki. Many wikis have style guides that dictate how infoboxes should be used.
Accessibility: Ensure your infobox is accessible to users with disabilities. Provide alt text for images and use clear, concise language.
Common Infobox Parameters
Here's a list of common parameters used in infoboxes:
`name` or `title`: The name of the subject.
`image`: The filename of an image.
`caption`: The caption for the image.
`birthdate`: The birthdate of a person.
`deathdate`: The deathdate of a person.
`birthplace`: The place of birth.
`occupation`: The person's occupation.
`nationality`: The person's nationality.
`location`: The location of a place.
`coordinates`: The geographical coordinates of a place.
`population`: The population of a place.
`area`: The area of a place.
`founded`: The founding date of an organization.
`headquarters`: The headquarters location of an organization.
`genre`: The genre of a film, book, or game.
`director`: The director of a film.
`author`: The author of a book.
`developer`: The developer of a game.
`release_date`: The release date of a film, book, or game.
`website`: The official website of the subject.
These are just a few examples. The specific parameters you use will depend on the subject of your article and the purpose of the infobox. Understanding Fibonacci retracement levels can be similar to understanding the parameters within an infobox – both involve identifying key elements and their relationships.

Template:Infobox – A Beginner's Guide
This article provides a comprehensive introduction to the `Template:Infobox` tag in MediaWiki, specifically geared towards users new to wiki editing. Infoboxes are a crucial part of a well-structured and informative wiki, offering a concise summary of key facts about a topic. We will cover what infoboxes are, why they're useful, how to use them, common parameters, customization, troubleshooting, and best practices. This guide is written for MediaWiki 1.40.
What is an Infobox?
An infobox (short for "information box") is a standardized template used to present a summary of vital information about a subject in a consistent and visually appealing format. Typically located in the top-right corner of a wiki page, the infobox acts as a quick reference guide for readers. Think of it as a snapshot of the most important details. Unlike free-form text within the article body, infoboxes are structured, using predefined fields (parameters) to display data. This standardization aids readability and allows for easy comparison between different topics. For example, an infobox for a country might include fields for population, capital, official language, and area. An infobox for a stock might include fields for ticker symbol, company name, industry, and current price. The aim is to present essential information in a concise, easily digestible manner. Understanding Help:Templates is fundamental to understanding infoboxes; they *are* templates.
Why Use Infoboxes?
Infoboxes offer several significant advantages:
**Improved Readability:** A well-formatted infobox allows readers to quickly grasp the core details of a topic without having to scan through large blocks of text.
**Consistency:** Using templates ensures consistent presentation across all articles, making the wiki more professional and user-friendly. This consistency helps readers navigate and understand the information presented. Compare this to the chaotic appearance of articles without consistent formatting.
**Data Summarization:** Infoboxes condense complex information into a manageable format, highlighting key facts.
**Navigation:** Infoboxes often contain links to related articles, enhancing navigation within the wiki.
**Data Mining & Automated Processing:** The structured data within infoboxes can be used for automated tasks such as generating lists, reports, and other derived content. This is particularly useful for large wikis with extensive databases of information.
**Visual Appeal:** Infoboxes break up the monotony of text and add visual interest to a page.
How to Use an Infobox: A Step-by-Step Guide
1. **Find an Existing Infobox Template:** Before creating a new infobox, check if one already exists for your topic. Browse the Special:Templates page to search for relevant templates. For example, if you're writing about a chemical compound, search for "Infobox chemical." Using an existing template is *always* preferred, as it ensures consistency and reduces maintenance.
2. **Include the Template in Your Article:** Once you've found a suitable template, include it in your article using the following syntax:
Replace "Infobox Chemical" with the actual name of the template. This will insert the basic structure of the infobox into your article.
3. **Populate the Parameters:** Infobox templates have predefined parameters (fields) that you need to fill in with specific data. The documentation for each template will list these parameters and explain their purpose. You can find the documentation by clicking the "What links here" link on the template's page (e.g., Special:WhatLinksHere/Template:Infobox Chemical). Parameters are typically specified as `parameter_name = parameter_value`. For example:
```wiki
{{Infobox Chemical
name = Water
formula = H₂O
molar_mass = 18.015 g/mol
density = 1.00 g/cm³
}}
```
4. **Preview and Edit:** Always preview your changes before saving the article. This allows you to check that the infobox is displaying correctly and that all the data is accurate. Edit the parameters as needed to refine the appearance and content of the infobox.
Common Infobox Parameters
While the specific parameters vary depending on the template, some common ones include:
**name:** The primary name of the subject.
**image:** The name of an image file to display in the infobox. Use `image = Example.jpg`.
**caption:** A caption for the image.
**alt:** Alternative text for the image (for accessibility).
**label1/data1, label2/data2, etc.:** Generic parameters for adding custom labels and data. These are useful when a template doesn't have a specific parameter for a particular piece of information.
**unit1, unit2, etc.:** Units associated with the data values.
**link1, link2, etc.:** Links associated with the data values.
**color:** Background color of the infobox (use cautiously).
**above:** Text that appears above the main content of the infobox.
**below:** Text that appears below the main content of the infobox.
The specific parameters and their usage are *always* documented on the template's page. Refer to that documentation for accurate information.
Customizing Infoboxes
While using existing templates is recommended, you may sometimes need to customize them to suit your specific needs. There are several ways to do this:
**Using Generic Parameters:** As mentioned earlier, `label1/data1`, `label2/data2`, etc., allow you to add custom fields without modifying the template itself.
**Creating New Templates:** If you need significant customization, you can create a new infobox template. This requires a good understanding of MediaWiki template syntax and is best left to experienced users. See Help:Creating templates for more information.
**Modifying Existing Templates (with Caution):** If you have the necessary permissions, you can modify existing templates. However, this should be done with extreme caution, as changes to templates can affect many articles. Always discuss significant changes with other editors before implementing them. Consider creating a sub-template for customization instead of directly altering the main template. This allows for easier rollback if necessary.
**Using Conditional Statements:** You can use conditional statements (e.g., `#if`, `#ifeq`) within templates to display different content based on the values of certain parameters. This allows for greater flexibility and adaptability.
Troubleshooting Infobox Issues
Here are some common problems you might encounter when working with infoboxes and how to fix them:
**Infobox Not Displaying:** Ensure you've included the template correctly using the `Template:Template Name` syntax. Check for typos in the template name. Make sure the template exists.
**Incorrect Data Displaying:** Double-check the parameter values you've entered. Ensure you're using the correct units and formatting. Consult the template documentation for guidance.
**Image Not Displaying:** Verify that the image file exists and is uploaded to the wiki. Ensure you've entered the correct image name in the `image` parameter. Check the image's alt text.
**Infobox Formatting Issues:** Incorrect parameter usage or syntax errors can cause formatting problems. Review the template documentation and your code carefully. Use the preview function to identify and correct errors.
**Template Errors:** If a template contains errors, it may not display correctly. Check the template's page for error messages. Report the error to the template's maintainer.
Best Practices for Infoboxes
**Consistency is Key:** Use existing templates whenever possible. If you create a new template, ensure it's consistent with the style and format of other infoboxes on the wiki.
**Accuracy:** Ensure that all the data in the infobox is accurate and up-to-date. Cite your sources if necessary.
**Conciseness:** Keep the infobox concise and focused on the most important information. Avoid including unnecessary details.
**Accessibility:** Provide alternative text for images to ensure accessibility for users with visual impairments.
**Documentation:** Document your templates clearly, explaining the purpose of each parameter.
**Maintainability:** Write templates that are easy to maintain and update.
**Avoid Excessive Customization:** While customization is possible, avoid making changes that deviate significantly from the standard template format.
**Test Thoroughly:** Always test your infoboxes thoroughly before saving the article.
**Collaboration:** Discuss significant changes to templates with other editors before implementing them.
Advanced Infobox Techniques
**Template Loops:** For displaying lists of data, you can use template loops (using parser functions like `#recurse`).
**Data Structures:** Utilize data structures within templates to organize and manage complex information.
**Modules:** Leverage Lua modules to create more powerful and flexible templates. This requires advanced programming knowledge. See Help:Lua for details.
**External Data Sources:** Integrate data from external sources (e.g., databases, APIs) using extensions like Wikidata.

Introduction
The “Blow-Off Top” is a crucial pattern for traders, particularly those involved in binary options, to recognize. It signals a potential reversal of a strong uptrend, often preceding a significant and rapid price decline. Understanding this pattern can help traders avoid being caught on the wrong side of the market and potentially profit from the anticipated downturn. This article will delve into the characteristics of a Blow-Off Top, its causes, how to identify it, and strategies for trading it, specifically within the context of binary options trading. We will also cover the risks associated with trading this pattern and how to mitigate them.
What is a Blow-Off Top?
A Blow-Off Top is a technical analysis pattern that occurs after a prolonged uptrend. It's characterized by a final surge in price, accompanied by significantly increased trading volume, followed by a sharp and substantial price drop. This final surge is often fueled by speculative buying, creating a temporary peak before the trend reverses. The “blow-off” refers to the explosive nature of the final move before the collapse. It’s not simply a pullback or a consolidation; it’s a dramatic and often unexpected reversal.
Think of it like inflating a balloon – the more air you pump in (the longer the uptrend and increasing volume), the more pressure builds. Eventually, the balloon reaches its limit and bursts (the blow-off top and subsequent price collapse).
Causes of a Blow-Off Top
Several factors can contribute to the formation of a Blow-Off Top:
Exhaustion of Buyers: After a sustained uptrend, the number of new buyers willing to enter the market diminishes. The remaining buyers are often more speculative and less committed.
Profit-Taking: Long-term investors who profited from the uptrend begin to take profits, adding selling pressure.
News or Events: Unexpected negative news or events can trigger a sudden shift in sentiment and accelerate the reversal.
Speculation & FOMO (Fear Of Missing Out): The final surge is often driven by short-term traders and speculators who fear missing out on further gains, pushing the price to unsustainable levels.
Market Manipulation: In some cases, large players may intentionally create a Blow-Off Top to profit from the subsequent decline. This is less common but possible.
Identifying a Blow-Off Top requires careful observation of price action and volume analysis. Here are key characteristics to look for:
Prolonged Uptrend: The pattern typically occurs after a substantial and sustained uptrend.
Increased Volume: Volume should be steadily increasing throughout the uptrend, culminating in a significant spike during the final surge. This is *crucial*. A blow-off top *without* a volume spike is often just a normal correction.
Accelerating Price Increase: The final surge in price is often steeper than previous moves in the uptrend. The rate of increase accelerates, creating a parabolic-like curve.
Breakaway Gap: A gap up in price can sometimes signal the start of the final surge.
Divergence:Technical divergence between price and momentum indicators (like MACD or RSI) can foreshadow a reversal. For example, if the price is making new highs but the RSI is making lower highs, it suggests weakening momentum.
Failed Breakouts: Attempts to break through key resistance levels may fail, indicating a loss of buying momentum.
Wide-Spreading Bars: The candlesticks during the final surge often have wide bodies, reflecting the intense buying and selling pressure.
Sharp Reversal: The most definitive sign is a sharp and rapid price decline after the final surge.
Blow-Off Tops in Binary Options Trading
Binary options traders can utilize the Blow-Off Top pattern to predict the direction of price movement and execute trades accordingly. However, it's important to understand the nuances of trading this pattern with binary options.
Put Options: The primary way to profit from a Blow-Off Top is by purchasing put options. A put option gives you the right, but not the obligation, to sell an asset at a specific price (the strike price) before a specific date (the expiration date). If the price declines as anticipated, the put option will be "in the money" and you will receive a payout.
Timing is Critical: The timing of your put option purchase is crucial. Buying too early can result in a losing trade if the price continues to rise for a short period. Buying too late can reduce your potential profit.
Expiration Date: Choose an appropriate expiration date for your put option. A shorter expiration date will offer a higher payout but also a greater risk of losing the trade if the price doesn't decline quickly enough. A longer expiration date will offer a lower payout but more time for the price to move in your favor.
Strike Price: Select a strike price that is slightly below the current market price. This will maximize your potential profit if the price declines significantly.
Here's a table summarizing binary options strategies for Blow-Off Tops:
{'{'}| class="wikitable"
|+ Binary Options Strategies for Blow-Off Tops
|!-| Strategy | Description | Risk Level | Expiration Time |
|-| Put Option | Purchase a put option anticipating a price decline. | High | Short-term (minutes to hours) |
|-| High/Low Option | Predict the price will be lower at expiration than the current price. | Medium | Short-term (minutes to hours) |
|-| Boundary Option | Predict the price will stay *below* a specified boundary. | Medium-High | Short-term to Medium-term (hours to days) |
|}
Risk Management and Mitigation
Trading a Blow-Off Top pattern involves inherent risks. Here's how to manage and mitigate them:
Confirmation: Don't trade solely on the appearance of a Blow-Off Top. Wait for confirmation of the reversal, such as a break below a key support level or a significant decline in volume.
Stop-Loss Orders: If you're trading traditional options or CFDs alongside binary options for hedging, use stop-loss orders to limit your potential losses. While not directly applicable to standard binary options, understanding risk management is crucial.
Position Sizing: Never risk more than a small percentage of your trading capital on a single trade. A general rule of thumb is to risk no more than 1-2% of your account balance per trade.
Diversification: Don't put all your eggs in one basket. Diversify your trading portfolio across different assets and strategies.
Understand Market Context: Consider the broader market context before trading a Blow-Off Top. Is the overall market bullish or bearish? Are there any major economic events scheduled that could impact the price?
Beware of False Signals: Not all Blow-Off Tops are genuine. Sometimes, the price may reverse slightly before continuing its uptrend. Be prepared for false signals and adjust your strategy accordingly.
Use Multiple Timeframes: Analyze the pattern on multiple timeframes to get a more comprehensive view of the market.
Blow-Off Top vs. Other Reversal Patterns
It's important to differentiate a Blow-Off Top from other reversal patterns:
Head and Shoulders: A Head and Shoulders pattern is a more gradual reversal pattern with distinct left shoulder, head, and right shoulder formations. The volume pattern is different.
Double Top/Bottom:Double Tops/Bottoms involve two attempts to break through a resistance/support level. They are less dramatic than Blow-Off Tops.
Rounding Top: A Rounding Top is a more gradual and less explosive reversal pattern.
The key difference is the *speed* and *volume* of the final surge in a Blow-Off Top. It's a much more violent reversal than these other patterns.
Example of a Blow-Off Top (Hypothetical)
Imagine a stock has been steadily rising for six months, driven by positive news and strong earnings reports. Volume has been consistently increasing. In the final week, the stock experiences a massive surge in price, with volume spiking to record levels. News headlines proclaim "Stock to $100!" However, a critical analyst report is released questioning the company's valuation. The stock immediately plunges, erasing all of the gains from the previous week. This is a classic example of a Blow-Off Top. A trader who recognized the pattern could have purchased put options before the decline and profited from the reversal.
Bollinger Bands - Using volatility to identify potential trading opportunities.
Conclusion
The Blow-Off Top is a powerful pattern that can signal a significant reversal of a strong uptrend. By understanding its characteristics, causes, and how to trade it, binary options traders can potentially profit from the anticipated decline. However, it's crucial to remember that trading this pattern involves risks, and effective risk management is essential for protecting your capital. Always confirm the pattern, use appropriate position sizing, and stay informed about market context.
