Template:Infobox event
Template:Infobox event is a standardized template used on Wikipedia and other MediaWiki-based wikis to provide a concise, visually appealing summary of information about an event. It's a crucial tool for organizing and presenting data consistently across numerous articles. This article will comprehensively guide beginners through understanding, utilizing, and even customizing the `Infobox event` template. We will cover its purpose, parameters, usage examples, customization options, common issues, and best practices. We will also touch on related templates and how to troubleshoot problems. Understanding this template is fundamental to contributing effectively to wikis that utilize it, particularly those dealing with historical events, sporting competitions, festivals, and other time-bound occurrences.
Purpose and Benefits
The primary purpose of the `Infobox event` template is to present key facts about an event in a standardized format. This offers several benefits:
Consistency: Ensures all articles about events follow a uniform structure, making information easily accessible and comparable.
Readability: The box format highlights crucial information, improving the overall readability of the article.
Navigation: Often includes links to related articles, enhancing wiki navigation.
Data Organization: Provides a structured way to organize event details, aiding in data retrieval and analysis.
Visual Appeal: A visually distinct infobox breaks up large blocks of text and makes the article more engaging.
Without a standardized template like `Infobox event`, articles could become cluttered and inconsistent, making it difficult for readers to quickly grasp the essential details of an event. This is particularly important in large wikis where users may be seeking specific information efficiently.
Basic Usage
The `Infobox event` template is implemented by copying the template code and filling in the relevant parameters with specific data. Here's a basic example:
This code will generate an infobox displaying the information provided for each parameter. Let's break down each parameter.
Parameters Explained
The `Infobox event` template uses a variety of parameters to capture different aspects of an event. Here's a detailed explanation of each:
`name` (Required): The official name of the event. This is the most important parameter and should be accurate and concise.
`image` (Optional): The filename of an image related to the event. It's best to use images already uploaded to the wiki. Ensure the image is relevant and has appropriate copyright permissions. Consider using File:…… syntax directly within the caption for more control over image size and alignment.
`caption` (Optional): A brief description of the image. This adds context and clarifies the image's relevance to the event.
`date` (Optional): The date(s) of the event. Use a consistent date format (e.g., 14 October 1066, 2023-10-27). Utilize ISO 8601 date format for clarity and compatibility.
`location` (Optional): The geographical location where the event took place. Be as specific as possible.
`combatant1`, `combatant2`, ... (Optional): The names of the parties involved in a conflict or competition. You can use as many `combatant` parameters as necessary (e.g., `combatant3`, `combatant4`). For non-conflict events, these parameters are not applicable.
`commander1`, `commander2`, ... (Optional): The leaders of the involved parties (if applicable). Similar to `combatant`, you can use multiple `commander` parameters.
`result` (Optional): The outcome of the event. (e.g., Norman victory, Draw, Cancelled).
`casualties` (Optional): The number of casualties (if applicable). Indicate if the figures are estimates.
`deaths` (Optional): The number of deaths (if applicable). More specific than casualties.
`injuries` (Optional): The number of injuries (if applicable).
`type` (Optional): The type of event (e.g., Battle, Festival, Earthquake, Election). This helps categorize the event. Consider using established categories.
`cause` (Optional): The cause or reason for the event. This is particularly relevant for disasters or conflicts.
`partof` (Optional): If the event is part of a larger series or conflict, specify it here (e.g., Norman Conquest, World War II). Link to the relevant article.
`website` (Optional): The official website of the event (if applicable).
`footnotes` (Optional): Allows you to add footnotes to the infobox. Use standard wiki footnote syntax.
`label1`, `data1`, `label2`, `data2`, ... (Optional): These allow you to add custom labels and data to the infobox. This is useful for events with unique characteristics that aren't covered by the standard parameters. Use these sparingly to avoid clutter.
Advanced Usage and Customization
While the basic parameters cover most events, you can further customize the `Infobox event` template:
Styling: While direct CSS styling within the template is generally discouraged, you can influence the appearance by using appropriate image sizes and captions.
Conditional Parameters: Using …|… or similar conditional statements within the template code, you can display parameters based on specific conditions. This requires editing the template itself, which should only be done by experienced users.
Custom Labels: As mentioned earlier, `label1`, `data1`, etc., allow you to add custom information. Be mindful of consistency and clarity when using these.
Template Documentation: Always consult the template's documentation page (usually linked from the template itself) for the most up-to-date information and available parameters. Template documentation is crucial for understanding the template’s capabilities.
Using Modules: More complex customization can be achieved using Lua modules. This requires advanced wiki editing skills.
Common Issues and Troubleshooting
Incorrect Parameter Names: Ensure you're using the correct parameter names. Typos can prevent the template from displaying correctly.
Missing Required Parameters: The `name` parameter is required. Without it, the infobox won't function.
Image Issues: If the image doesn't appear, check that the filename is correct, the image is uploaded to the wiki, and you have the necessary permissions to use it. Also, verify the image's syntax (e.g., `…`).
Date Formatting: Use a consistent date format. ISO 8601 (YYYY-MM-DD) is recommended.
Template Conflicts: If other templates are interfering with the infobox, try adjusting the order in which they're placed in the article.
Rendering Errors: If the infobox doesn't render at all, check the wiki's error logs for clues. Errors often indicate a syntax error in the template code or an issue with a parameter value.
Blank Infobox: If the infobox appears but is empty, double-check all parameter values for errors or omissions.

Template:Start date
Template:Start date is a MediaWiki template designed to display a date in a standardized, human-readable format, particularly useful for indicating the start date of events, projects, or periods within a wiki. This article provides a comprehensive guide to understanding, using, and customizing the `Template:Start date` template for beginners. It will cover its purpose, parameters, examples, potential issues, and related templates. This template is invaluable for maintaining consistency when documenting timelines and historical data.
Purpose
The primary purpose of `Template:Start date` is to consistently format dates across a wiki. Without a standardized template, dates might appear in various formats (e.g., January 1, 2023, 1/1/2023, 2023-01-01), leading to visual clutter and potential confusion. This template ensures that all start dates are displayed in a uniform manner, enhancing readability and professionalism. It’s particularly useful for projects that involve tracking timelines, historical events, or scheduled activities. Effective date formatting is crucial for data integrity and usability, especially when dealing with Time series analysis.
Basic Usage
The simplest way to use the template is to provide a date in YYYY-MM-DD format. The template will then automatically format it into a more readable format, typically "January 1, 2023".
The `Template:Start date` template accepts several parameters to customize the output. Here's a breakdown of each parameter:
1 (Date): This is the *required* parameter. It represents the start date in YYYY-MM-DD format. For example, `2023-12-25` represents December 25, 2023. Incorrectly formatted dates will likely result in errors or unexpected output.
format: (Optional) This parameter allows you to specify a custom date format using PHP's `date()` function format codes. This provides a high degree of flexibility. For example, `format=d.m.Y` would output "25.12.2023". Refer to the PHP date() function documentation for a complete list of format codes. Using custom formats requires a good understanding of these codes.
month: (Optional) This parameter allows you to explicitly specify the month name. This is useful if you want to override the template's automatic month detection, perhaps for localization or specific stylistic requirements. Accepts the month name as a string (e.g., `month=December`).
day: (Optional) This parameter allows you to explicitly specify the day of the month. Similar to 'month', this overrides the template's automatic day detection. Accepts the day as a string (e.g., `day=25`).
year: (Optional) This parameter allows you to explicitly specify the year. Overrides the template's automatic year detection. Accepts the year as a string (e.g., `year=2023`).
hideyear: (Optional) A boolean parameter (true/false) that controls whether the year is displayed. If set to `true`, the year will be omitted. Default is `false` (year is displayed). Example: `hideyear=true`. This can be useful when the context clearly implies the year.
showfullmonth: (Optional) A boolean parameter (true/false) that determines whether the full month name is displayed. If set to `true`, "January" will be displayed instead of "Jan". Default is `false`. Example: `showfullmonth=true`.
link: (Optional) A boolean parameter (true/false) that determines whether the date is linked to a corresponding page (e.g., a page for that specific date). Default is `false`. Example: `link=true`. This is helpful for creating navigable timelines.
separator: (Optional) Allows you to change the separator character between the day, month and year. Default is a comma and a space (", "). Example: `separator=.` will output the date with a period as a separator.
Examples
Here are some examples demonstrating how to use the template with different parameters:
Incorrect Date Format: The most common issue is providing the date in a format other than YYYY-MM-DD. Ensure the date is entered correctly.
Invalid Format Codes: If using the `format` parameter, ensure the format codes are valid PHP `date()` function codes. Incorrect codes will result in errors or unexpected output. Consult the PHP date() function documentation.
Missing Pages for Linked Dates: If the `link` parameter is set to `true`, but the corresponding date page does not exist, the output will be a red link. Create the page to resolve this.
Template Conflicts: Rarely, conflicts can occur if other templates or extensions modify the output of this template. If this happens, investigate the interaction between the templates and extensions.
Localization: The default output is in English. For wikis using other languages, consider using the `month` parameter to specify the month name in the desired language or exploring localization extensions. This is related to Localization strategies.
Related Templates
Several other templates complement `Template:Start date` and provide related functionality:
Template:End date: Displays an end date in a standardized format. Often used in conjunction with `Template:Start date` to define a period.
Template:Duration: Calculates and displays the duration between a start and end date.

Advanced Usage and Customization
For more advanced users, the `Template:Start date` template can be extended and customized through the use of parser functions and Lua modules. This allows for more complex date calculations, conditional formatting, and integration with other wiki features. For example, you could use parser functions to dynamically determine whether a date falls within a specific range or to display different text based on the date. This involves a deeper understanding of MediaWiki's template system and programming languages like Lua. Consider studying MediaWiki extension development for more complex customizations.
Best Practices
Consistency: Always use `Template:Start date` (or a similar standardized template) for all start dates in your wiki.
YYYY-MM-DD Format: Provide the date in YYYY-MM-DD format to ensure correct parsing.
Use Parameters Wisely: Only use the optional parameters when necessary to customize the output. Avoid unnecessary complexity.
Test Thoroughly: After making changes to the template or its usage, test thoroughly to ensure the output is as expected.
Document Your Changes: If you modify the template, document your changes clearly for future maintainers.
Consider Accessibility: Ensure the date format is accessible to users with disabilities. Use clear and concise language.
Understand Date Interpretation: Be mindful of regional differences in date interpretation (e.g., MM/DD/YYYY vs. DD/MM/YYYY) and choose a format that is unambiguous for your target audience. This is relevant to Global market analysis.

**Conditional Parameters:** Some parameters may only be relevant for certain individuals. For example, the `label` parameter is only applicable to musicians. Don’t include parameters that don’t apply to the subject.
**Formatting:** Use standard MediaWiki formatting within the infobox parameters. This includes links (link), bold text (`text`), and italic text (`text`).
**Image Size:** You can control the size of the image using the `image_size` parameter. For example: `|image_size=200px`.
**Collapsible Sections:** For very long infoboxes, consider using collapsible sections to improve readability. This can be achieved using templates like `Template:Collapsible list`.
**Avoiding Redundancy:** Don’t repeat information that is already prominently displayed in the main text of the article. The infobox should *summarize* information, not duplicate it.
**Documentation:** Always refer to the template's documentation page for the most up-to-date information and a complete list of parameters: Template:Infobox person/doc. This is critical for staying informed about changes and new features.
**Parameter Aliases:** Some parameters have aliases for convenience. For example, `birthdate` is an alias for `birth_date`. However, it’s best to use the official parameter names for clarity.
Troubleshooting Common Issues
**Infobox Not Displaying:** Check for syntax errors in your code. Make sure all curly braces are properly matched and that parameter names are spelled correctly. Also, verify that the image file exists and is accessible.
**Image Not Displaying:** Ensure the image filename is correct and that the image has been uploaded to the wiki. Check the image's page to see if it has any restrictions or licensing issues.
**Incorrect Formatting:** Double-check your formatting within the parameters. Use standard MediaWiki formatting and avoid using HTML tags.
**Unexpected Results:** If you’re experiencing unexpected results, try clearing your browser cache or viewing the page in a different browser. Also, consult the template’s documentation or ask for help on the wiki’s help pages.
**Overly Long Infobox:** If the infobox becomes too long, consider using collapsible sections or removing less essential parameters. Prioritize the most important information.
Best Practices for Effective Infoboxes
**Accuracy:** Ensure all information in the infobox is accurate and verifiable. Cite sources where appropriate.
**Conciseness:** Keep the information concise and to the point. Avoid lengthy descriptions.
**Relevance:** Only include parameters that are relevant to the subject of the article.
**Consistency:** Follow the guidelines established in the template’s documentation and maintain consistency across all biographical articles.
**Accessibility:** Consider accessibility when creating infoboxes. Use descriptive captions for images and ensure the text is readable.
**Regular Updates:** Keep the infobox up-to-date with the latest information. Monitor the article for changes and update the infobox accordingly.

Best Practices
Consistency: Always use `Template:Start date` (or a similar standardized template) for all start dates in your wiki.
YYYY-MM-DD Format: Provide the date in YYYY-MM-DD format to ensure correct parsing.
Use Parameters Wisely: Only use the optional parameters when necessary to customize the output. Avoid unnecessary complexity.
Test Thoroughly: After making changes to the template or its usage, test thoroughly to ensure the output is as expected.
Document Your Changes: If you modify the template, document your changes clearly for future maintainers.
Consider Accessibility: Ensure the date format is accessible to users with disabilities. Use clear and concise language.
Understand Date Interpretation: Be mindful of regional differences in date interpretation (e.g., MM/DD/YYYY vs. DD/MM/YYYY) and choose a format that is unambiguous for your target audience. This is relevant to Global market analysis.

Template:End date
Template:End date is a MediaWiki template designed to dynamically display an end date, often used in conjunction with start dates to represent the duration of an event, project, or period. It’s particularly useful in contexts like financial data analysis, project management within a wiki, event planning, or tracking the lifespan of a specific market trend. This article provides a comprehensive guide to using the `Template:End date` template, covering its functionality, parameters, examples, and best practices. It assumes a basic understanding of MediaWiki syntax.
Purpose
The primary purpose of `Template:End date` is to present a date in a consistent and easily readable format across a wiki. Instead of manually typing dates, which can lead to inconsistencies and errors, this template allows you to input a date in a standardized way, and it will render it according to the wiki's default date format. More importantly, it is designed to be used *with* a corresponding Template:Start date template, to easily calculate and display the duration between the two dates. This is crucial for tracking time-sensitive information, especially in fields like Technical Analysis where timing is paramount.
Functionality
The template takes a date as input and formats it according to the wiki’s configured date preferences. It leverages the built-in MediaWiki parser functions, specifically `{{#time}}`, to achieve this formatting. The template essentially acts as a wrapper around this parser function, providing a simplified and standardized interface for date display. Its core functionality also allows for easy integration with other templates to calculate differences between dates, as explained later. Understanding the underlying principles of Candlestick Patterns can be enhanced by accurately representing the timeframes involved, and this template supports that.
Parameters
The `Template:End date` template accepts a single, mandatory parameter:
`1` (or unnamed parameter): This parameter represents the date to be displayed. The date must be in a format that MediaWiki's parser functions can understand. Commonly accepted formats include:
* `YYYY-MM-DD` (e.g., `2023-10-27`) - This is the *recommended* format for consistency.
* `YYYY-MM` (e.g., `2023-10`) - Displays the date to the month level.
* `YYYY` (e.g., `2023`) - Displays the date to the year level.
* Unix timestamp (e.g., `1698403200`) - A numerical representation of the date.
* Natural language (e.g., `tomorrow`, `next Friday`) - MediaWiki will attempt to interpret these, but this is less reliable. Avoid these for critical data.
The template does *not* currently support named parameters, relying solely on the positional parameter `1`. Future iterations might include named parameters for more advanced formatting options. Consider also Fibonacci Retracement when analyzing time-based data, as it often correlates with date-specific price movements.
Usage Examples
Here are several examples demonstrating how to use the `Template:End date` template:
This will display: `October 27, 2023` (The timestamp corresponds to October 27, 2023).
Example 5: Combining with Template:Start date to calculate duration
This is where the real power of these templates becomes apparent. First, assume you have a Template:Start date template that functions similarly, taking a date as a parameter. Then:

Template:Start date
Template:Start date is a MediaWiki template designed to display a date in a standardized, human-readable format, particularly useful for indicating the start date of events, projects, or periods within a wiki. This article provides a comprehensive guide to understanding, using, and customizing the `Template:Start date` template for beginners. It will cover its purpose, parameters, examples, potential issues, and related templates. This template is invaluable for maintaining consistency when documenting timelines and historical data.
Purpose
The primary purpose of `Template:Start date` is to consistently format dates across a wiki. Without a standardized template, dates might appear in various formats (e.g., January 1, 2023, 1/1/2023, 2023-01-01), leading to visual clutter and potential confusion. This template ensures that all start dates are displayed in a uniform manner, enhancing readability and professionalism. It’s particularly useful for projects that involve tracking timelines, historical events, or scheduled activities. Effective date formatting is crucial for data integrity and usability, especially when dealing with Time series analysis.
Basic Usage
The simplest way to use the template is to provide a date in YYYY-MM-DD format. The template will then automatically format it into a more readable format, typically "January 1, 2023".
The `Template:Start date` template accepts several parameters to customize the output. Here's a breakdown of each parameter:
1 (Date): This is the *required* parameter. It represents the start date in YYYY-MM-DD format. For example, `2023-12-25` represents December 25, 2023. Incorrectly formatted dates will likely result in errors or unexpected output.
format: (Optional) This parameter allows you to specify a custom date format using PHP's `date()` function format codes. This provides a high degree of flexibility. For example, `format=d.m.Y` would output "25.12.2023". Refer to the PHP date() function documentation for a complete list of format codes. Using custom formats requires a good understanding of these codes.
month: (Optional) This parameter allows you to explicitly specify the month name. This is useful if you want to override the template's automatic month detection, perhaps for localization or specific stylistic requirements. Accepts the month name as a string (e.g., `month=December`).
day: (Optional) This parameter allows you to explicitly specify the day of the month. Similar to 'month', this overrides the template's automatic day detection. Accepts the day as a string (e.g., `day=25`).
year: (Optional) This parameter allows you to explicitly specify the year. Overrides the template's automatic year detection. Accepts the year as a string (e.g., `year=2023`).
hideyear: (Optional) A boolean parameter (true/false) that controls whether the year is displayed. If set to `true`, the year will be omitted. Default is `false` (year is displayed). Example: `hideyear=true`. This can be useful when the context clearly implies the year.
showfullmonth: (Optional) A boolean parameter (true/false) that determines whether the full month name is displayed. If set to `true`, "January" will be displayed instead of "Jan". Default is `false`. Example: `showfullmonth=true`.
link: (Optional) A boolean parameter (true/false) that determines whether the date is linked to a corresponding page (e.g., a page for that specific date). Default is `false`. Example: `link=true`. This is helpful for creating navigable timelines.
separator: (Optional) Allows you to change the separator character between the day, month and year. Default is a comma and a space (", "). Example: `separator=.` will output the date with a period as a separator.
Examples
Here are some examples demonstrating how to use the template with different parameters:
Incorrect Date Format: The most common issue is providing the date in a format other than YYYY-MM-DD. Ensure the date is entered correctly.
Invalid Format Codes: If using the `format` parameter, ensure the format codes are valid PHP `date()` function codes. Incorrect codes will result in errors or unexpected output. Consult the PHP date() function documentation.
Missing Pages for Linked Dates: If the `link` parameter is set to `true`, but the corresponding date page does not exist, the output will be a red link. Create the page to resolve this.
Template Conflicts: Rarely, conflicts can occur if other templates or extensions modify the output of this template. If this happens, investigate the interaction between the templates and extensions.
Localization: The default output is in English. For wikis using other languages, consider using the `month` parameter to specify the month name in the desired language or exploring localization extensions. This is related to Localization strategies.
Related Templates
Several other templates complement `Template:Start date` and provide related functionality:
Template:End date: Displays an end date in a standardized format. Often used in conjunction with `Template:Start date` to define a period.
Template:Duration: Calculates and displays the duration between a start and end date.
Template:Date: A more general-purpose date formatting template, offering more options than `Template:Start date`.
Template:Now: Displays the current date and time.
Template:Age: Calculates and displays the age based on a birth date.
Template:Timeline: Creates visual timelines based on a series of dates.
Template:Event timeline: Similar to timeline, but optimized for event-based timelines.
Template:Year: Displays only the year from a given date.
Template:Month: Displays only the month from a given date.
Template:Day: Displays only the day from a given date.
Advanced Usage and Customization
For more advanced users, the `Template:Start date` template can be extended and customized through the use of parser functions and Lua modules. This allows for more complex date calculations, conditional formatting, and integration with other wiki features. For example, you could use parser functions to dynamically determine whether a date falls within a specific range or to display different text based on the date. This involves a deeper understanding of MediaWiki's template system and programming languages like Lua. Consider studying MediaWiki extension development for more complex customizations.

```
This will display:
```
Start Date: October 20, 2023
End Date: October 27, 2023
Duration: 7 days
```
The `{{#time:d|...|...}}` parser function calculates the difference in days between the start and end dates. You can change the `d` to `m` for months, `y` for years, or `h` for hours, etc. Remember to explore different Chart Patterns to identify potential turning points based on these durations.
Example 6: Using with a variable
```wiki
{{#let: myDate = 2024-01-15 }}Template loop detected: Template:End date
```
This will display: January 15, 2024. Useful for dynamic date assignment.
Integration with other Templates and Parser Functions
The `Template:End date` template is designed to work seamlessly with other MediaWiki features. Here's how:
`{{#time}}` Parser Function: As mentioned earlier, the template internally utilizes `{{#time}}`. You can directly use this function within the template if you need more complex date formatting. For example, `{{#time:l, d F Y|2023-10-27}}` would display "Friday, 27 October 2023."
`{{#if}}` Conditional Statement: You can use `{{#if}}` to conditionally display the end date based on certain criteria. For example:
```wiki
{{#if: {{#time:Y|Template loop detected: Template:End date}} = 2023 | End Date is in 2023 | End Date is not in 2023}}
```
`{{#switch}}` Multi-Conditional Statement: Similar to `{{#if}}`, `{{#switch}}` allows you to display different content based on the end date's value.
`{{#var}}` and `{{#let}}` Variable Assignment: You can store dates in variables using `{{#let}}` and then use `{{#var}}` to reference them within the `Template:End date`. This is useful for dynamic date calculations.
Template:Start date and Duration Calculation: As demonstrated in the examples, combining `Template:End date` with `Template:Start date` and the `{{#time}}` parser function is the most powerful application of this template.
Understanding Elliott Wave Theory requires precise timing, and these templates can assist in marking potential wave boundaries.
Best Practices
Use YYYY-MM-DD Format: Always use the `YYYY-MM-DD` format for the date parameter to ensure consistency and avoid ambiguity.
Consistency is Key: Use the template consistently throughout the wiki to maintain a uniform date display style.
Test Thoroughly: After creating or modifying the template, test it with various date formats to ensure it functions as expected.
Document Usage: Clearly document the template's parameters and usage examples on its documentation page.
Consider Localization: If your wiki serves a multilingual audience, consider implementing localization features to display dates according to the user's preferred locale. This may require more complex template logic.
Error Handling: While not currently implemented, future versions could include error handling to gracefully handle invalid date formats.
Avoid Natural Language Dates: While MediaWiki *can* interpret natural language dates, it's prone to errors. Always use a standardized date format.
Combine with Start Date Template: Maximize the utility of this template by always using it in conjunction with the Template:Start date template for duration calculations. This is highly relevant when examining Moving Averages and their crossover points.
Be mindful of Time Zones: Dates are often interpreted in UTC. If your data requires a specific time zone, consider incorporating time zone handling into your templates or calculations. This is vital for Forex Trading strategies.
Potential Enhancements
Named Parameters: Adding named parameters would allow for more flexible formatting options (e.g., `format=F j, Y` for "October 27, 2023").
Error Handling: Implementing error handling to gracefully handle invalid date formats and display a user-friendly error message.
Localization Support: Adding support for different date formats based on the user's locale.
Time Zone Support: Allowing users to specify a time zone for the date.
Integration with External Data Sources: Developing a mechanism to fetch dates from external data sources, such as APIs.
Customizable Output: Adding options to customize the output format beyond what's available through `{{#time}}`. These features would greatly enhance its utility for Day Trading and swing trading applications. Analyzing Relative Strength Index (RSI) often requires precise date tracking.
Troubleshooting
Incorrect Date Format: If the date is not displaying correctly, double-check that you are using a valid and supported date format (preferably YYYY-MM-DD).
Parser Function Errors: If you are using the template in conjunction with other parser functions and encounter errors, carefully review the syntax of those functions.
Wiki Configuration: Ensure that your wiki's date format settings are configured correctly. Incorrect wiki settings will affect how the template renders dates.
Template Conflicts: If you have other templates that might be interfering with the `Template:End date`, try disabling them temporarily to see if that resolves the issue. Understanding Bollinger Bands often requires accurate date-based calculations.
Cache Issues: Occasionally, the wiki's cache might be outdated. Try purging the cache to see if that fixes the problem. This is particularly important when analyzing MACD signals.
Check for Typos: Carefully review the template code and your usage of it for any typos or syntax errors. Even a small mistake can prevent the template from working correctly. Keep in mind the principles of Japanese Candlesticks when interpreting date-based price patterns.

Flash Crash refers to an extremely rapid, significant, and temporary decline in market prices, followed by a relatively quick recovery. These events are characterized by their speed and volatility, often occurring within minutes. While "flash crashes" are not new phenomena, the rise of algorithmic trading and high-frequency trading (HFT) has increased their frequency and potential impact. The most well-known flash crash occurred on May 6, 2010, in the U.S. stock market, but similar events have happened in other markets, including currencies and commodities.
Background and History
Before the widespread adoption of electronic trading, market declines, even steep ones, typically unfolded over hours or days. The speed of information dissemination and order execution was limited by human intervention and manual processes. With the advent of computer-based trading systems, particularly in the late 1990s and early 2000s, trading became significantly faster and more automated.
The increasing prevalence of algorithmic trading, where computers execute trades based on pre-programmed instructions, and HFT, which focuses on exploiting tiny price discrepancies with extremely fast execution speeds, changed the dynamics of market liquidity and price discovery. These technologies were initially touted for their ability to enhance market efficiency and reduce transaction costs. However, they also introduced new vulnerabilities.
Early instances of rapid price declines foreshadowed the 2010 flash crash. These events, though less dramatic, highlighted the potential for automated trading systems to exacerbate market movements. The 2010 event served as a wake-up call, prompting regulators to investigate the causes and implement safeguards. However, flash crashes, though less severe, have continued to occur in subsequent years, demonstrating the inherent complexities of modern financial markets.
The May 6, 2010 Flash Crash
The May 6, 2010, flash crash remains the most infamous example of this phenomenon. Around 2:42 PM EDT, the Dow Jones Industrial Average (DJIA) began a steep decline. Within minutes, the DJIA plummeted nearly 1,000 points – a drop of approximately 9% – before partially recovering. Numerous individual stocks experienced even more dramatic, temporary declines, with some briefly trading at prices of just $0.01.
The recovery was almost as rapid as the decline, with the market rebounding significantly by the end of the day. However, the event triggered widespread panic and raised serious questions about the stability of the U.S. stock market.
Key Events During the Crash
**2:30 PM EDT:** Initial selling pressure began, potentially triggered by a large sell order from a mutual fund.
**2:42 PM EDT:** The Dow Jones Industrial Average began its precipitous drop.
**2:45 PM EDT:** A large number of trades were executed at extremely low prices, reflecting a temporary loss of liquidity. Many stocks traded at fractions of a penny.
**2:49 PM EDT:** The decline began to slow, and buying pressure started to emerge.
**3:00 PM EDT:** The market began to recover, with prices rebounding sharply.
**Layering:** A controversial trading strategy involving the placement of multiple orders to create a false impression of buying or selling pressure. While not illegal at the time, layering exacerbated the downward momentum. See Order Book Analysis for more details.
**High-Frequency Trading (HFT):** HFT firms, using sophisticated algorithms, reacted to the initial selling pressure by rapidly withdrawing liquidity and exacerbating the decline. Their algorithms were designed to prioritize self-preservation, leading to a cascade of selling. Study Algorithmic Trading Strategies for more information.
**Order Book Imbalances:** The sudden surge in selling orders overwhelmed the market's ability to absorb the volume, creating a significant imbalance in the order book. Understanding Order Flow is crucial here.
**Lack of Circuit Breakers:** Existing circuit breakers, designed to halt trading during extreme market declines, were not triggered quickly enough to prevent the initial plunge. Explore Risk Management Techniques to understand circuit breakers.
**Intermarket Dynamics:** The futures market, particularly the E-mini S&P 500 futures contract, played a significant role in amplifying the decline. The connection between futures and spot markets is critical. Research Futures Trading to understand this relationship.
Subsequent Flash Crashes and Events
The 2010 flash crash wasn’t an isolated incident. Since then, several other, albeit less severe, flash crashes have occurred:
**August 2015:** A broad market decline impacted U.S. stocks, driven by concerns about China's economic slowdown. Although not as rapid as the 2010 crash, it highlighted the ongoing vulnerability of markets to external shocks.
**February 2018:** A series of rapid declines affected U.S. stocks, attributed to the unwinding of volatility-linked exchange-traded products (ETPs). This event exposed the risks associated with complex financial instruments. Learn about Volatility Trading for more detail.
**September 2023:** A brief but notable flash crash occurred in U.S. Treasury bonds, raising concerns about liquidity in the world's largest bond market.
These events demonstrate that the conditions that contribute to flash crashes—high-frequency trading, complex algorithmic strategies, and potential order book imbalances—persist in modern financial markets.
Impact of Flash Crashes
The impact of flash crashes can be significant, even if the decline is short-lived:
**Investor Confidence:** Flash crashes erode investor confidence in the stability of the market.
**Temporary Losses:** Investors who have orders executed during a flash crash may experience significant temporary losses.
**Market Disruption:** Flash crashes can disrupt the normal functioning of the market, leading to increased volatility and uncertainty.
**Regulatory Scrutiny:** These events typically trigger increased regulatory scrutiny and calls for stricter market safeguards.
**Liquidity Concerns:** Flash crashes can expose vulnerabilities in market liquidity, particularly during periods of stress. Explore Liquidity Analysis to understand these concerns.
Regulatory Responses and Safeguards
Following the 2010 flash crash, regulators implemented several measures to mitigate the risk of future events:
**Limit Up-Limit Down (LULD):** Rules that prevent trades from occurring outside specified price bands, designed to prevent extreme price movements. This is a form of Price Control Mechanism.
**Consolidated Audit Trail (CAT):** A system designed to track all trading activity in U.S. equity and options markets, providing regulators with a comprehensive view of market events.
**Enhanced Surveillance:** Increased monitoring of trading activity to detect and prevent manipulative trading practices, such as layering.
**Circuit Breakers:** Modifications to existing circuit breaker rules to trigger halts more quickly during extreme market declines. Learn about Trading Halts and their effects.
**Regulation ATS (Alternative Trading Systems):** Increased oversight of alternative trading systems, which play a significant role in HFT.
While these safeguards have reduced the frequency and severity of flash crashes, they have not eliminated the risk entirely. The market continues to evolve, and new vulnerabilities may emerge. Understanding Market Microstructure is essential for assessing these risks.
Trading Strategies Related to Flash Crashes (and Risk Management)
While predicting flash crashes is nearly impossible, understanding their dynamics can inform trading strategies:
**Stop-Loss Orders:** Crucial for limiting potential losses during periods of extreme volatility. Implement Trailing Stop Loss for dynamic protection.
**Position Sizing:** Reducing position sizes can limit the impact of a flash crash on overall portfolio value. Learn about Kelly Criterion for optimal position sizing.
**Diversification:** Diversifying across asset classes can help mitigate the impact of a flash crash in any single market.
**Volatility-Based Strategies:** Strategies that profit from increased volatility, such as Straddles and Strangles, can be used to hedge against potential losses.
**Mean Reversion Strategies:** Strategies that capitalize on the tendency for prices to revert to their historical averages may be profitable after a flash crash. (Caution: Requires careful timing.) Study Bollinger Bands and Relative Strength Index (RSI) for mean reversion signals.
**Avoid Trading During Low Liquidity:** Flash crashes are more likely to occur during periods of low liquidity, such as the open or close of trading. Consider Volume Weighted Average Price (VWAP) for better execution.
