Retrieve the Lowest Stock Price from the Last X Weeks

The x_week_low function empowers users to quickly reference the lowest daily price recorded for a given stock (or other supported symbols) over a specified number of weeks. This can be particularly useful when tracking market trends, confirming investment decisions, and managing portfolios – all without leaving the ease of your Excel spreadsheet.

Below, you’ll learn how the function works, explore detailed usage examples, and see how to maximize its benefits in real-world scenarios.

Why Use This Function?

• Ideal for rolling performance checks: Find the minimum daily price in a dynamic range (e.g., 2 weeks, 4 weeks, etc.).
• Real-time decision-making: Track near-term lows to spot potential buy points.
• Simple integration: Combine with other Excel functions (e.g., conditional logic, lookups, or charting) for deeper analysis.
• Automated outputs: No need to manually track or import data. Once set up, the function regularly retrieves the latest minimum price.
• Versatile usage: Works for most common US stocks, and may also retrieve data for certain ETFs, indexes, and other tradable instruments if supported.

How to Use in Excel

=x_week_low(Symbol, weeks)

1. Select a cell in your Excel spreadsheet where you want the result.
2. Type the formula “=x_week_low(” followed by the ticker symbol in quotes (e.g., "AAPL") and the number of weeks (e.g., 4).
3. Press Enter to confirm.
4. The function will return the lowest daily price for that symbol over the last “weeks” number of weeks.

Once entered, your Excel file will automatically fetch the relevant data from MarketXLS’ backend service. If there is any ongoing data refresh or if an invalid symbol is requested, the function may return "Refreshing" or "NA" until data is properly retrieved.

Parameters Explained

Example Usage

Basic Examples

1. Retrieving 4-Week Low for AAPL
   =x_week_low("AAPL", 4)
   • Returns the lowest Apple stock price in the last 4 weeks.

2. Checking 2-Week Low for MSFT
   =x_week_low("MSFT", 2)
   • Returns Microsoft’s lowest daily price within the last 14 days.

3. Invalid Symbol Example
   =x_week_low("INVALID", 3)
   • Returns "NA" if the symbol doesn’t exist or isn’t recognized.

Advanced Scenarios

1. Using Cell References
   If cell A1 contains the symbol "GOOG" and cell B1 contains the value 6, you can do:
   =x_week_low(A1, B1)
   • This dynamically references your desired symbol and weeks range, which is especially handy when building templates.

2. Integrating with Other Excel Functions
   =IF(x_week_low("TSLA", 8) < 1000, "Buy", "Hold")
   • Automate a conditional decision based on whether Tesla’s 8-week low is under $1000.

3. Trend Analysis with Charting
   • Retrieve the low price for multiple symbols (e.g., AAPL, NFLX, AMZN) in adjacent cells for a consistent date range.
   • Create a bar or line chart to quickly visualize how each stock’s near-term lows stack up against each other.

Common Questions and Troubleshooting

1. Why am I seeing "NA"?
   • Possible reasons:
   – The symbol is invalid or unsupported.
   – A non-numeric or negative weeks parameter was entered.
   – Data retrieval failed temporarily (e.g., network issues, invalid license).

2. Why do I get "Refreshing"?
   • This can occur if MarketXLS is currently updating its data cache. The function will return the correct week low after the refresh completes.

3. Can I use this function for non-US stocks or mutual funds?
   • While x_week_low is primarily used for US stocks, it may support certain other securities if the data is available. Check your MarketXLS plan or data coverage to confirm.

4. How often is the data updated?
   • MarketXLS regularly updates data. The function itself will call the most recent cached data. If new requests are queued, a short delay may occur.

Remember:

• This function is a quick way to view the minimum price within any recent set of weeks you choose.
• Combine x_week_low with other analytics in Excel to create powerful trading dashboards and actionable insights.
• Always double-check your parameters (symbol spelling and weeks value) to ensure accurate results.

By fully leveraging x_week_low in Excel with MarketXLS, you can streamline monitoring tasks, discover potential investment opportunities, and make data-driven decisions faster than ever before.
