Stream Real-Time Gamma Data with QM_Stream_Gamma

The QM_Stream_Gamma function provides real-time streaming of gamma values for a given stock or option symbol directly in Excel. By leveraging MarketXLS’s advanced data subscription and RTD (Real-Time Data) capabilities, you can track how the option’s delta changes as the underlying asset price moves—an essential metric for options traders and analysts.

Why Use This Function?

• Gain Real-Time Insights: Receive gamma data as it updates in real-time, providing immediate insight into option price sensitivity.
• Improved Options Analysis: Understand how a small change in the underlying stock price can significantly impact an option's delta.
• Sensitivity Tracking: Combine gamma with other option Greeks (e.g., delta, theta) to develop strategic trading models.
• Automated Excel Integration: The function keeps your spreadsheet live without needing constant manual refreshes, ideal for intraday analysis.
• Versatile Application: Capitalize on the ability to view gamma for various symbols, from single-leg options to complex multi-leg strategies.

How to Use in Excel

1. Open Excel with MarketXLS installed.
2. In any cell, type the above formula.
3. Replace "SYMBOL" with the desired stock/option symbol.
4. Press Enter to view the real-time gamma value.

• If you have a valid data subscription, the cell will automatically update in real time.

Example Usage

Basic Examples

1. Single Stock Example
   =QM_Stream_Gamma("AAPL")
   This retrieves the real-time gamma of Apple’s option chain contracts (if available), streaming directly in your spreadsheet.

2. Cell Reference Example
   Suppose cell A1 contains the symbol TSLA. Use:
   =QM_Stream_Gamma(A1)
   This automatically updates the gamma in real time for the symbol in cell A1.

3. Simple Option Symbol Example
   =QM_Stream_Gamma("TSLA230120C700")
   If properly recognized by your data provider, this retrieves the gamma of the 700-strike call option on Tesla, expiring on a specified date.

Advanced Scenarios

• Multi-Symbol Dashboard: Create a grid in Excel where each row references a different option symbol:

• “AAPL230120P100” (Put option)
• “TSLA230120C700” (Call option)
• “AMZN230120C3500”
  Each cell will show the real-time gamma, updating as the market moves.

• Combined Greeks Analysis: Use QM_Stream_Gamma alongside other option Greeks like QM_Stream_Delta or QM_Stream_Theta to create robust option trading models in Excel. Display all values side by side for a comprehensive view of option sensitivity.

• Intraday Trading Strategy: Automate alerting by using Excel’s conditional formatting. For instance, highlight gamma cells that exceed a certain threshold, indicating potential high-risk or high-reward situations.
