Stream Real-Time Stock Open Price Data

The QM_Stream_Open function lets you access live “Open” price data for a given security directly in Excel. It leverages real-time RTD/streaming technology, ensuring that whenever the market updates, your worksheet reflects the latest open price. By integrating real-time data directly into your workflow, you can make more informed decisions faster without ever leaving Excel.

Why Use This Function?

• Gain instant access to the live “Open” price of a stock.
• Monitor multiple securities in real-time without manual refreshes.
• Automate trading dashboards, watchlists, or portfolio trackers.
• Quickly identify and respond to market changes.
• Integrate seamlessly with Excel’s built-in formulas, charts, and pivot tables.

How to Use in Excel

=QM_Stream_Open("SYMBOL")

1. Enter the function into an Excel cell.
2. Replace "SYMBOL" with the ticker symbol you want real-time open price data for (e.g., "AAPL").
3. Press Enter to display streaming open price data in your sheet.

Remember that you need a valid MarketXLS license and an active data subscription configured properly. If there are any subscription or licensing issues, you will receive an error message or an NA result.

Parameters Explained

• Only one parameter is needed. Ensure it’s a non-empty string.
• Input is case-insensitive; the function automatically normalizes the symbol.

Example Usage

Basic Examples

1. =QM_Stream_Open("AAPL")
   • Streams the real-time open price of Apple (AAPL).
   • The cell updates in real-time as the market changes.

2. =QM_Stream_Open("MSFT")
   • Displays the live open price of Microsoft (MSFT).
   • Perfect for building dashboards tracking multiple stocks side by side.

3. =QM_Stream_Open("GOOG")

Advanced Scenarios

• Combining with Excel’s charting:

• Use =QM_Stream_Open("AAPL") in one cell and reference that cell in a chart to visualize intraday movements of Apple’s open price.
  • Building real-time alerts:
• Combine QM_Stream_Open with additional logic (e.g., an IF function comparing two real-time cells) to trigger alerts when the open price hits a threshold.
  • Multi-stock watchlist:
• Put multiple =QM_Stream_Open() formulas across a row or column, each referencing a different symbol, to create a dynamic watchlist.

Common Questions and Troubleshooting

1. Why am I getting “NA” or a blank cell?
   • The ticker symbol might be invalid, blank, or incorrectly formatted. Double-check the symbol and try again.
   • Your MarketXLS license or data subscription may be inactive or not configured.

2. Why does the function show a configuration error message?
   • Make sure your data provider settings in MarketXLS are fully set up under Settings ? Data Subscriptions.

3. Do I need to update the data manually?
   • No. This function uses real-time RTD streaming, so data automatically stays current.

4. What if the market is closed?
   • The value may not update until the next trading session or until your data provider pushes new updates.

By using the QM_Stream_Open function from MarketXLS, you can easily create a powerful, real-time trading view in Excel. Whether you want a simple single-symbol open price tracker or a complex multi-symbol watchlist with alerts, this function helps you stay on top of market events.
