Templates

1. Templates

Templates are a fundamental, yet often initially daunting, aspect of MediaWiki editing. They allow for the creation of reusable content blocks, reducing redundancy, ensuring consistency, and simplifying complex edits. This article will provide a comprehensive introduction to templates for beginners, covering their creation, usage, parameters, and advanced techniques. We will also briefly touch upon how templates can be used to structure financial information such as stock data, economic indicators, and trading strategy summaries.

What are Templates?

At their core, a template is a pre-defined page containing wiki markup. Instead of repeatedly typing the same information on multiple pages, you create a template once and then *transclude* it – effectively inserting the template's content into any page where it's needed. Think of them like form letters; the basic structure remains the same, but you can fill in specific details each time you use it.

Why use templates? Here are several key benefits:

• **Consistency:** Templates ensure that information is presented in a uniform manner across the wiki. This is crucial for maintaining a professional and easily navigable resource. For example, a template for displaying a stock's key statistics (price, volume, P/E ratio) will always present that data in the same format.
• **Reduced Redundancy:** Avoid copy-pasting the same content repeatedly. This reduces the wiki's size, makes updates easier, and minimizes the risk of inconsistencies.
• **Simplified Editing:** Instead of editing the same content in multiple places, you only need to edit the template. Changes are automatically reflected on all pages where the template is used. This is especially valuable when updating information like current exchange rates or economic data.
• **Complex Structures:** Templates can handle complex formatting and logic, making it easier to create tables, infoboxes, and other structured content. Consider a template that calculates and displays a Moving Average Convergence Divergence (MACD) indicator for a stock.
• **Code Reusability:** Facilitates the reuse of code snippets and structured data across multiple pages.

Creating a Template

To create a template:

1. **Navigate to the Template Page:** Type `Template:` followed by the template name in the search box. For example, `Template:StockInfo`. If the page doesn't exist, you'll be given the option to create it. 2. **Write the Template Code:** Use standard MediaWiki markup to define the content of the template. This can include text, images, tables, and other wiki elements. 3. **Save the Page:** Once you're satisfied with the template code, save the page.

Let's create a simple example template called `Template:Greeting`.

```wiki This is a greeting template! Hello, User:Templates! ```

This template will display "This is a greeting template! Hello, [username]!" where "[username]" is replaced by the username of the page where the template is used.

Using a Template

To use a template on a page, use the following syntax:

```wiki

1. Template:Greeting

Template:Greeting is a fundamental and highly versatile template within the MediaWiki environment, designed to dynamically generate personalized greetings for users. This article provides a comprehensive guide to understanding, utilizing, and customizing this template, catering specifically to beginners. We will cover its core functionality, parameters, usage examples, advanced customization options, troubleshooting common issues, and its role within the broader context of wiki user engagement.

What is a Template?

Before diving into the specifics of Template:Greeting, it’s crucial to understand what a Template is in MediaWiki. Templates are pre-defined sets of wiki markup that can be inserted into pages to consistently display specific content. They act as reusable building blocks, preventing repetitive typing and ensuring uniformity across the wiki. Think of them as functions in programming – you provide certain inputs (parameters), and the template generates a pre-defined output. Using templates promotes efficient content management and a consistent user experience. They are essential for maintaining a professional and organized wiki. Related concepts include Help:Variables and Help:Magic words.

Core Functionality of Template:Greeting

Template:Greeting’s primary purpose is to display a customized greeting message to a user, often incorporating their username. It typically leverages MediaWiki's built-in parser functions to determine the current time and tailor the greeting accordingly (e.g., "Good morning," "Good afternoon," "Good evening"). Beyond a simple greeting, the template can also be extended to display welcome messages, recent activity notifications, or links to helpful resources for new users. It's a crucial element in fostering a welcoming and engaging community environment. Understanding Help:Linking and referencing is key to adding helpful links within the greeting.

Parameters

Template:Greeting utilizes several parameters to control its behavior and output. These parameters are specified when the template is included on a page using the `` syntax. Here's a breakdown of the common parameters:

• `username`: (Optional) The username to greet. If omitted, the template will automatically attempt to determine the current user’s username.
• `greeting`: (Optional) Allows you to override the default greeting message. This can be useful for special occasions or themed greetings.
• `time-format`: (Optional) Specifies the format for displaying the time. Defaults to a 12-hour format. Acceptable values include "12" or "24".

• **Styling Issues:** If the colors or other styling are not displaying as expected, double-check the HTML color codes and ensure they are valid.

Template Documentation

Every template should have comprehensive documentation. This is typically created on a subpage of the template, such as `Template:Greeting/doc`. The documentation should include:

• A clear description of the template’s purpose.
• A list of all available parameters, with detailed explanations and examples.
• Usage examples demonstrating common use cases.
• Troubleshooting tips for common issues.
• Links to related templates and documentation.

Relationship to Trading and Financial Analysis (for context, as requested)

While seemingly unrelated, the principles behind a well-designed template like Template:Greeting mirror best practices in financial analysis and trading. Just as a template provides a consistent and reliable output based on input parameters, successful trading relies on consistent application of strategies and analysis. Consider these analogies:

• **Parameters as Indicators:** The template’s parameters (username, greeting, time-format) are analogous to technical indicators like Moving Averages, MACD, or RSI. Each parameter modifies the output, just as each indicator provides a different perspective on market data.
• **Template Logic as Trading Strategy:** The logic within the template (determining the greeting based on time) resembles a trading strategy. A defined set of rules (time of day) leads to a specific action (greeting). Similar to a Breakout strategy, the template responds to a specific condition.
• **Customization as Risk Management:** The ability to customize the template reflects the need for risk management in trading. Adjusting parameters allows for tailoring the output to specific circumstances, just as adjusting position size or stop-loss orders manages risk.

• **Volatility and Parameter Sensitivity:** The sensitivity of the template's output to parameter changes mirrors the concept of volatility in financial markets. Small changes in input can lead to significant differences in the outcome.
• **Correlation & Parameter Interdependence:** The interaction between different template parameters is similar to correlations between different assets.
• **Support and Resistance Levels & Template Limits:** The limitations of the template (e.g., the types of parameters it accepts) are like support and resistance levels in a market – boundaries that define the range of possible outcomes.
• **Fibonacci Retracements & Template Refinement:** Iteratively refining the template's code and parameters is analogous to using Fibonacci Retracements to identify potential price targets.
• **Elliot Wave Theory & Template Evolution:** The evolution of a template over time, with new features and improvements, can be compared to Elliot Wave Theory, where patterns repeat at different scales.
• **Candlestick Patterns & Template Visualizations:** The visual presentation of the greeting (colors, images) can be considered a form of visualization, similar to how Candlestick patterns provide a visual representation of price action.
• **Bollinger Bands & Template Boundaries:** The parameters of the template define its boundaries, similar to how Bollinger Bands define a range around a moving average.
• **Ichimoku Cloud & Template Conditions:** The conditional logic within the template (e.g., displaying different greetings based on user groups) is analogous to the complex conditions defined by the Ichimoku Cloud.
• **Stochastic Oscillator & Template Momentum:** The dynamic nature of the greeting (changing based on the time of day) can be compared to the momentum indicators like the Stochastic Oscillator.
• **Average True Range (ATR) & Template Variability:** The degree to which the template’s output can vary based on parameter changes is similar to the Average True Range (ATR), which measures market volatility.
• **Donchian Channels & Template Range:** The range of possible outputs from the template, defined by its parameters, can be compared to Donchian Channels, which define a price range over a specific period.
• **Parabolic SAR & Template Acceleration:** The ability to customize the template to respond quickly to changing conditions is analogous to the Parabolic SAR, which accelerates as prices move.
• **Volume Weighted Average Price (VWAP) & Template Importance:** The frequency with which the template is used can be compared to the Volume Weighted Average Price (VWAP), which reflects the importance of price levels based on trading volume.
• **Harmonic Patterns & Template Complexity:** The intricate logic and interdependencies within a highly customized template can be compared to the complexity of Harmonic Patterns.
• **Renko Charts & Template Simplification:** Simplifying the template to focus on essential parameters is analogous to using Renko Charts to filter out noise and focus on significant price movements.
• **Heikin Ashi Charts & Template Smoothing:** Using the template to smooth out variations in the user experience is similar to using Heikin Ashi Charts to smooth out price data.
• **Keltner Channels & Template Volatility:** The template’s responsiveness to changes in user data or system settings is similar to how Keltner Channels adapt to changing market volatility.
• **Pivot Points & Template Key Levels:** The key parameters of the template can be considered pivot points that define its behavior.

This requires a basic understanding of MediaWiki markup and parser functions. You can access the template’s source code by clicking the "View source" tab on the Template:Greeting/doc page (or the template itself if documentation doesn't exist).

Here are some advanced customization possibilities:

• **Conditional Greetings:** Use `#if` statements to display different greetings based on user groups (e.g., administrators, registered users, anonymous users). This requires using the `{{#ifeq:Template:USERGROUPS...}}` construct. See Help:Conditional statements for more details.
• **Dynamic Content:** Integrate with other templates or extensions to display dynamic content based on user preferences or recent activity.
• **Custom Time Formats:** Use the `Template:Formattime` parser function to create highly customized time formats. Refer to Help:FormatTime for comprehensive documentation.
• **Error Handling:** Implement error handling to gracefully handle cases where a username is not provided or an image file is missing. Use `#ifexist` to check for file existence.
• **Localization:** Support multiple languages by using the Extension:Translate extension and defining translations for the greeting messages.

Troubleshooting Common Issues

• **Template Not Displaying:** Ensure that the template is correctly included on the page using the `` syntax. Check for typos in the template name.
• **Incorrect Username:** If the template is not displaying the correct username, verify that the user is logged in. If you are specifying a username manually, double-check the spelling.
• **Time Not Displaying Correctly:** Ensure that the server’s time is correctly configured. Verify the `time-format` parameter is set to the desired value ("12" or "24").
• **Image Not Displaying:** Make sure the image file exists in the wiki and that the filename is correct. Verify that the image syntax is correct (e.g., `File:Example.png`).
• **Styling Issues:** If the colors or other styling are not displaying as expected, double-check the HTML color codes and ensure they are valid.

Template Documentation

Every template should have comprehensive documentation. This is typically created on a subpage of the template, such as `Template:Greeting/doc`. The documentation should include:

• A clear description of the template’s purpose.
• A list of all available parameters, with detailed explanations and examples.
• Usage examples demonstrating common use cases.
• Troubleshooting tips for common issues.
• Links to related templates and documentation.

Relationship to Trading and Financial Analysis (for context, as requested)

While seemingly unrelated, the principles behind a well-designed template like Template:Greeting mirror best practices in financial analysis and trading. Just as a template provides a consistent and reliable output based on input parameters, successful trading relies on consistent application of strategies and analysis. Consider these analogies:

• **Parameters as Indicators:** The template’s parameters (username, greeting, time-format) are analogous to technical indicators like Moving Averages, MACD, or RSI. Each parameter modifies the output, just as each indicator provides a different perspective on market data.
• **Template Logic as Trading Strategy:** The logic within the template (determining the greeting based on time) resembles a trading strategy. A defined set of rules (time of day) leads to a specific action (greeting). Similar to a Breakout strategy, the template responds to a specific condition.
• **Customization as Risk Management:** The ability to customize the template reflects the need for risk management in trading. Adjusting parameters allows for tailoring the output to specific circumstances, just as adjusting position size or stop-loss orders manages risk.
• **Consistency as Backtesting:** The consistent output of the template is akin to the need for backtesting in trading. A reliable template ensures predictable results, just as backtesting validates the performance of a trading strategy.
• **Documentation as Trading Journal:** The documentation for the template is like a trading journal. It records the rules, parameters, and expected outcomes, allowing for review and improvement.
• **Market Trends & Template Updates:** Just as market trends change, requiring adjustments to trading strategies (e.g., shifting from a Trend Following to a Mean Reversion approach), templates may need updates to remain relevant and effective.
• **Volatility and Parameter Sensitivity:** The sensitivity of the template's output to parameter changes mirrors the concept of volatility in financial markets. Small changes in input can lead to significant differences in the outcome.
• **Correlation & Parameter Interdependence:** The interaction between different template parameters is similar to correlations between different assets.
• **Support and Resistance Levels & Template Limits:** The limitations of the template (e.g., the types of parameters it accepts) are like support and resistance levels in a market – boundaries that define the range of possible outcomes.
• **Fibonacci Retracements & Template Refinement:** Iteratively refining the template's code and parameters is analogous to using Fibonacci Retracements to identify potential price targets.
• **Elliot Wave Theory & Template Evolution:** The evolution of a template over time, with new features and improvements, can be compared to Elliot Wave Theory, where patterns repeat at different scales.
• **Candlestick Patterns & Template Visualizations:** The visual presentation of the greeting (colors, images) can be considered a form of visualization, similar to how Candlestick patterns provide a visual representation of price action.
• **Bollinger Bands & Template Boundaries:** The parameters of the template define its boundaries, similar to how Bollinger Bands define a range around a moving average.
• **Ichimoku Cloud & Template Conditions:** The conditional logic within the template (e.g., displaying different greetings based on user groups) is analogous to the complex conditions defined by the Ichimoku Cloud.
• **Stochastic Oscillator & Template Momentum:** The dynamic nature of the greeting (changing based on the time of day) can be compared to the momentum indicators like the Stochastic Oscillator.
• **Average True Range (ATR) & Template Variability:** The degree to which the template’s output can vary based on parameter changes is similar to the Average True Range (ATR), which measures market volatility.
• **Donchian Channels & Template Range:** The range of possible outputs from the template, defined by its parameters, can be compared to Donchian Channels, which define a price range over a specific period.
• **Parabolic SAR & Template Acceleration:** The ability to customize the template to respond quickly to changing conditions is analogous to the Parabolic SAR, which accelerates as prices move.
• **Volume Weighted Average Price (VWAP) & Template Importance:** The frequency with which the template is used can be compared to the Volume Weighted Average Price (VWAP), which reflects the importance of price levels based on trading volume.
• **Harmonic Patterns & Template Complexity:** The intricate logic and interdependencies within a highly customized template can be compared to the complexity of Harmonic Patterns.
• **Renko Charts & Template Simplification:** Simplifying the template to focus on essential parameters is analogous to using Renko Charts to filter out noise and focus on significant price movements.
• **Heikin Ashi Charts & Template Smoothing:** Using the template to smooth out variations in the user experience is similar to using Heikin Ashi Charts to smooth out price data.
• **Keltner Channels & Template Volatility:** The template’s responsiveness to changes in user data or system settings is similar to how Keltner Channels adapt to changing market volatility.
• **Pivot Points & Template Key Levels:** The key parameters of the template can be considered pivot points that define its behavior.

This will display "This is a greeting template! Hello, Alice! You are 30 years old."

Named Parameters

While using numbered parameters is simple, it can become confusing when you have many parameters. Named parameters offer a more readable and maintainable solution.

To define a named parameter, use the `{{{parameter_name=default_value}}}` syntax. The `default_value` is optional and will be used if the parameter is not specified when the template is used.

Let's modify our `Template:Greeting` template to use named parameters:

```wiki This is a greeting template! Hello, John! You are unknown years old. ```

Now, you can use the template like this:

```wiki

1. Template:Greeting

Template:Greeting is a fundamental and highly versatile template within the MediaWiki environment, designed to dynamically generate personalized greetings for users. This article provides a comprehensive guide to understanding, utilizing, and customizing this template, catering specifically to beginners. We will cover its core functionality, parameters, usage examples, advanced customization options, troubleshooting common issues, and its role within the broader context of wiki user engagement.

What is a Template?

Before diving into the specifics of Template:Greeting, it’s crucial to understand what a Template is in MediaWiki. Templates are pre-defined sets of wiki markup that can be inserted into pages to consistently display specific content. They act as reusable building blocks, preventing repetitive typing and ensuring uniformity across the wiki. Think of them as functions in programming – you provide certain inputs (parameters), and the template generates a pre-defined output. Using templates promotes efficient content management and a consistent user experience. They are essential for maintaining a professional and organized wiki. Related concepts include Help:Variables and Help:Magic words.

Core Functionality of Template:Greeting

Template:Greeting’s primary purpose is to display a customized greeting message to a user, often incorporating their username. It typically leverages MediaWiki's built-in parser functions to determine the current time and tailor the greeting accordingly (e.g., "Good morning," "Good afternoon," "Good evening"). Beyond a simple greeting, the template can also be extended to display welcome messages, recent activity notifications, or links to helpful resources for new users. It's a crucial element in fostering a welcoming and engaging community environment. Understanding Help:Linking and referencing is key to adding helpful links within the greeting.

Parameters

Template:Greeting utilizes several parameters to control its behavior and output. These parameters are specified when the template is included on a page using the `` syntax. Here's a breakdown of the common parameters:

• `username`: (Optional) The username to greet. If omitted, the template will automatically attempt to determine the current user’s username.
• `greeting`: (Optional) Allows you to override the default greeting message. This can be useful for special occasions or themed greetings.
• `time-format`: (Optional) Specifies the format for displaying the time. Defaults to a 12-hour format. Acceptable values include "12" or "24".
• `show-time`: (Optional) A boolean value (true/false) that determines whether the current time is displayed alongside the greeting. Defaults to "true".
• `custom-message`: (Optional) Allows you to add a completely custom message after the greeting. This parameter is perfect for displaying specific announcements or welcome information.
• `image`: (Optional) Specifies the name of an image to be displayed alongside the greeting. Use standard MediaWiki image syntax (e.g., `File:Example.png`).
• `link`: (Optional) A URL to link from the greeting. Useful for linking to a user's profile or a welcome page.
• `linktext`: (Optional) The text to display for the link specified by the `link` parameter.
• `bgcolor`: (Optional) Sets the background color of the greeting box. Accepts standard HTML color codes (e.g., `#f0f0f0`).
• `textcolor`: (Optional) Sets the text color of the greeting. Accepts standard HTML color codes.

Usage Examples

Here are several examples demonstrating how to use Template:Greeting with different parameters:

1. **Basic Usage (Automatic Username & Default Greeting):**

This will display "This is a greeting template! Hello, Charlie! You are unknown years old." because the `age` parameter was not specified, so the default value "unknown" is used.

Template Documentation

It's crucial to document your templates so that other editors understand how to use them. Create a subpage called `Template:TemplateName/doc` to document your template. This page should include:

• **A description of the template's purpose.**
• **A list of all parameters, their names, descriptions, and default values.**
• **Examples of how to use the template.**

For example, for `Template:Greeting`, you would create a page called `Template:Greeting/doc` with the following content:

1. Template:Greeting

Template:Greeting is a fundamental and highly versatile template within the MediaWiki environment, designed to dynamically generate personalized greetings for users. This article provides a comprehensive guide to understanding, utilizing, and customizing this template, catering specifically to beginners. We will cover its core functionality, parameters, usage examples, advanced customization options, troubleshooting common issues, and its role within the broader context of wiki user engagement.

What is a Template?

Before diving into the specifics of Template:Greeting, it’s crucial to understand what a Template is in MediaWiki. Templates are pre-defined sets of wiki markup that can be inserted into pages to consistently display specific content. They act as reusable building blocks, preventing repetitive typing and ensuring uniformity across the wiki. Think of them as functions in programming – you provide certain inputs (parameters), and the template generates a pre-defined output. Using templates promotes efficient content management and a consistent user experience. They are essential for maintaining a professional and organized wiki. Related concepts include Help:Variables and Help:Magic words.

Core Functionality of Template:Greeting

Template:Greeting’s primary purpose is to display a customized greeting message to a user, often incorporating their username. It typically leverages MediaWiki's built-in parser functions to determine the current time and tailor the greeting accordingly (e.g., "Good morning," "Good afternoon," "Good evening"). Beyond a simple greeting, the template can also be extended to display welcome messages, recent activity notifications, or links to helpful resources for new users. It's a crucial element in fostering a welcoming and engaging community environment. Understanding Help:Linking and referencing is key to adding helpful links within the greeting.

Parameters

Template:Greeting utilizes several parameters to control its behavior and output. These parameters are specified when the template is included on a page using the `` syntax. Here's a breakdown of the common parameters:

• `username`: (Optional) The username to greet. If omitted, the template will automatically attempt to determine the current user’s username.
• `greeting`: (Optional) Allows you to override the default greeting message. This can be useful for special occasions or themed greetings.
• `time-format`: (Optional) Specifies the format for displaying the time. Defaults to a 12-hour format. Acceptable values include "12" or "24".
• `show-time`: (Optional) A boolean value (true/false) that determines whether the current time is displayed alongside the greeting. Defaults to "true".
• `custom-message`: (Optional) Allows you to add a completely custom message after the greeting. This parameter is perfect for displaying specific announcements or welcome information.
• `image`: (Optional) Specifies the name of an image to be displayed alongside the greeting. Use standard MediaWiki image syntax (e.g., `File:Example.png`).
• `link`: (Optional) A URL to link from the greeting. Useful for linking to a user's profile or a welcome page.
• `linktext`: (Optional) The text to display for the link specified by the `link` parameter.
• `bgcolor`: (Optional) Sets the background color of the greeting box. Accepts standard HTML color codes (e.g., `#f0f0f0`).
• `textcolor`: (Optional) Sets the text color of the greeting. Accepts standard HTML color codes.

Usage Examples

Here are several examples demonstrating how to use Template:Greeting with different parameters:

1. **Basic Usage (Automatic Username & Default Greeting):**

   ```wiki
   
   ```

   This will display a greeting like "Good morning, [Your Username]!" along with the current time.

2. **Specifying a Username:**

   ```wiki
   
   ```

   This will display "Good morning, ExampleUser!"

10. **Combining Parameters:**

   ```wiki
   
   ```

   This demonstrates how to combine multiple parameters for a comprehensive greeting message.

Advanced Customization

While the parameters described above cover most common use cases, Template:Greeting can be further customized by modifying the template’s source code. This requires a basic understanding of MediaWiki markup and parser functions. You can access the template’s source code by clicking the "View source" tab on the Template:Greeting/doc page (or the template itself if documentation doesn't exist).

Here are some advanced customization possibilities:

• **Conditional Greetings:** Use `#if` statements to display different greetings based on user groups (e.g., administrators, registered users, anonymous users). This requires using the `{{#ifeq:Template:USERGROUPS...}}` construct. See Help:Conditional statements for more details.
• **Dynamic Content:** Integrate with other templates or extensions to display dynamic content based on user preferences or recent activity.
• **Custom Time Formats:** Use the `Template:Formattime` parser function to create highly customized time formats. Refer to Help:FormatTime for comprehensive documentation.
• **Error Handling:** Implement error handling to gracefully handle cases where a username is not provided or an image file is missing. Use `#ifexist` to check for file existence.
• **Localization:** Support multiple languages by using the Extension:Translate extension and defining translations for the greeting messages.

Troubleshooting Common Issues

• **Template Not Displaying:** Ensure that the template is correctly included on the page using the `` syntax. Check for typos in the template name.
• **Incorrect Username:** If the template is not displaying the correct username, verify that the user is logged in. If you are specifying a username manually, double-check the spelling.
• **Time Not Displaying Correctly:** Ensure that the server’s time is correctly configured. Verify the `time-format` parameter is set to the desired value ("12" or "24").
• **Image Not Displaying:** Make sure the image file exists in the wiki and that the filename is correct. Verify that the image syntax is correct (e.g., `File:Example.png`).
• **Styling Issues:** If the colors or other styling are not displaying as expected, double-check the HTML color codes and ensure they are valid.

Template Documentation

Every template should have comprehensive documentation. This is typically created on a subpage of the template, such as `Template:Greeting/doc`. The documentation should include:

• A clear description of the template’s purpose.
• A list of all available parameters, with detailed explanations and examples.
• Usage examples demonstrating common use cases.
• Troubleshooting tips for common issues.
• Links to related templates and documentation.

Relationship to Trading and Financial Analysis (for context, as requested)

While seemingly unrelated, the principles behind a well-designed template like Template:Greeting mirror best practices in financial analysis and trading. Just as a template provides a consistent and reliable output based on input parameters, successful trading relies on consistent application of strategies and analysis. Consider these analogies:

• **Parameters as Indicators:** The template’s parameters (username, greeting, time-format) are analogous to technical indicators like Moving Averages, MACD, or RSI. Each parameter modifies the output, just as each indicator provides a different perspective on market data.
• **Template Logic as Trading Strategy:** The logic within the template (determining the greeting based on time) resembles a trading strategy. A defined set of rules (time of day) leads to a specific action (greeting). Similar to a Breakout strategy, the template responds to a specific condition.
• **Customization as Risk Management:** The ability to customize the template reflects the need for risk management in trading. Adjusting parameters allows for tailoring the output to specific circumstances, just as adjusting position size or stop-loss orders manages risk.
• **Consistency as Backtesting:** The consistent output of the template is akin to the need for backtesting in trading. A reliable template ensures predictable results, just as backtesting validates the performance of a trading strategy.
• **Documentation as Trading Journal:** The documentation for the template is like a trading journal. It records the rules, parameters, and expected outcomes, allowing for review and improvement.
• **Market Trends & Template Updates:** Just as market trends change, requiring adjustments to trading strategies (e.g., shifting from a Trend Following to a Mean Reversion approach), templates may need updates to remain relevant and effective.
• **Volatility and Parameter Sensitivity:** The sensitivity of the template's output to parameter changes mirrors the concept of volatility in financial markets. Small changes in input can lead to significant differences in the outcome.
• **Correlation & Parameter Interdependence:** The interaction between different template parameters is similar to correlations between different assets.
• **Support and Resistance Levels & Template Limits:** The limitations of the template (e.g., the types of parameters it accepts) are like support and resistance levels in a market – boundaries that define the range of possible outcomes.
• **Fibonacci Retracements & Template Refinement:** Iteratively refining the template's code and parameters is analogous to using Fibonacci Retracements to identify potential price targets.
• **Elliot Wave Theory & Template Evolution:** The evolution of a template over time, with new features and improvements, can be compared to Elliot Wave Theory, where patterns repeat at different scales.
• **Candlestick Patterns & Template Visualizations:** The visual presentation of the greeting (colors, images) can be considered a form of visualization, similar to how Candlestick patterns provide a visual representation of price action.
• **Bollinger Bands & Template Boundaries:** The parameters of the template define its boundaries, similar to how Bollinger Bands define a range around a moving average.
• **Ichimoku Cloud & Template Conditions:** The conditional logic within the template (e.g., displaying different greetings based on user groups) is analogous to the complex conditions defined by the Ichimoku Cloud.
• **Stochastic Oscillator & Template Momentum:** The dynamic nature of the greeting (changing based on the time of day) can be compared to the momentum indicators like the Stochastic Oscillator.
• **Average True Range (ATR) & Template Variability:** The degree to which the template’s output can vary based on parameter changes is similar to the Average True Range (ATR), which measures market volatility.
• **Donchian Channels & Template Range:** The range of possible outputs from the template, defined by its parameters, can be compared to Donchian Channels, which define a price range over a specific period.
• **Parabolic SAR & Template Acceleration:** The ability to customize the template to respond quickly to changing conditions is analogous to the Parabolic SAR, which accelerates as prices move.
• **Volume Weighted Average Price (VWAP) & Template Importance:** The frequency with which the template is used can be compared to the Volume Weighted Average Price (VWAP), which reflects the importance of price levels based on trading volume.
• **Harmonic Patterns & Template Complexity:** The intricate logic and interdependencies within a highly customized template can be compared to the complexity of Harmonic Patterns.
• **Renko Charts & Template Simplification:** Simplifying the template to focus on essential parameters is analogous to using Renko Charts to filter out noise and focus on significant price movements.
• **Heikin Ashi Charts & Template Smoothing:** Using the template to smooth out variations in the user experience is similar to using Heikin Ashi Charts to smooth out price data.
• **Keltner Channels & Template Volatility:** The template’s responsiveness to changes in user data or system settings is similar to how Keltner Channels adapt to changing market volatility.
• **Pivot Points & Template Key Levels:** The key parameters of the template can be considered pivot points that define its behavior.

Parameters

• `name`: The name of the person to greet. Default value: John.
• `age`: The age of the person. Default value: unknown.

```

Advanced Techniques

• **Conditional Statements:** Use `#if` statements to display different content based on parameter values. This is useful for creating templates that adapt to different situations. For instance, a template for displaying a stock's performance could show "Up" or "Down" based on whether the current price is higher or lower than the previous close.
• **Loops:** Use `#loop` or `#recurse` to iterate over lists or perform repetitive tasks. This is useful for creating templates that display multiple items, such as a list of trading signals.
• **Functions:** MediaWiki provides a number of built-in functions that can be used within templates to perform calculations, manipulate strings, and more. These functions can be extremely powerful for creating dynamic templates. For example, you could use a function to calculate the Relative Strength Index (RSI) and display it in a template.
• **TemplateData:** A JSON-based format for defining template parameters and documentation in a structured way. This allows for better integration with the visual editor.
• **Modules:** For more complex logic, consider using Lua modules. Modules allow you to write code in a more powerful and flexible language than the MediaWiki template language. Modules are particularly useful for creating templates that perform complex calculations or interact with external data sources. They're also critical for implementing advanced Elliott Wave analysis visualizations.

Templates and Financial Information

Templates are exceptionally useful for organizing and displaying financial data. Here are some examples:

• **Stock Infoboxes:** A template could display key stock information such as symbol, company name, current price, volume, P/E ratio, earnings per share, and a link to a financial news source. This ensures consistency in how stock data is presented across the wiki.
• **Economic Indicator Tables:** Templates can create tables displaying economic indicators like GDP growth, inflation rates, unemployment figures, and interest rates. The data could be updated regularly to provide current information. Consider linking to sources like the Bureau of Economic Analysis.
