ImpliedVolatility90d Function for 90-Day Implied Volatility

The ImpliedVolatility90d function in MarketXLS is designed to help you quickly retrieve 90-day implied volatility data for any stock symbol directly in Excel. Implied volatility is a key measure in understanding option pricing and market sentiment. With this function, traders and analysts can make more informed decisions by monitoring volatility trends within their Excel workflows.

Why Use This Function?

• Effortless Data Retrieval: Automatically fetch the latest 90-day implied volatility data without leaving Excel.
• Streamlined Analysis: Smoothly integrate implied volatility into existing spreadsheets and trading models for deeper insights.
• Versatile Date Handling: Optionally specify a start date to request historical volatility for a particular trading date.
• Reliable Data Caching: Benefit from caching that may help improve performance and reduce repeated requests.
• Options Strategy Support: Combine implied volatility data with your option pricing or volatility-driven trading strategies to refine entry and exit decisions.

How to Use in Excel

=ImpliedVolatility90d(Symbol, [StartDate])

• Symbol – required string representing the stock ticker (e.g., "AAPL").
• StartDate – optional date parameter used for fetching volatility as of a specific date. When omitted or if it is before the year 1978, the function returns the most recently available volatility data.

To use it in Excel, simply type the function in a cell, passing in your chosen symbol. Optionally, include a valid date to retrieve the volatility for that specific point in time.

Parameters Explained

• If “Symbol” is invalid, the function returns “NA.”
• If the MarketXLS license is not valid, the function returns a corresponding message indicating a licensing issue.

Example Usage

Basic Examples

1. Retrieve the latest 90-day implied volatility for AAPL:
   =ImpliedVolatility90d("AAPL")
   ? Returns the most recent 90-day implied volatility figure from the MarketXLS data feed.

2. Retrieve the latest 90-day implied volatility for MSFT:
   =ImpliedVolatility90d("MSFT")
   ? Provides Microsoft’s current 90-day implied volatility data.

Advanced Scenarios

1. Fetch Historical Data for a Specific Date:
   =ImpliedVolatility90d("AAPL", "03/15/2023")
   ? Attempts to return the 90-day implied volatility for AAPL specifically on March 15, 2023. If no data exists for that exact date, the function may return “NA.”

2. Integrating with Other Excel Functions:
   Suppose you want to compare implied volatility across multiple symbols on the same date. Combine it with an average function or reference another cell storing the date:
   =AVERAGE(
   ImpliedVolatility90d("AAPL", $B$2),
   ImpliedVolatility90d("MSFT", $B$2),
   ImpliedVolatility90d("AMZN", $B$2)
   )

3. Building an Options Trading Model:
   Use ImpliedVolatility90d in an options pricing dashboard to quickly see how volatility changes over time. This helps you watch for potential breakouts or significant volatility shifts ahead of earnings or major market events.

Common Questions and Troubleshooting

• Why am I getting “NA”?
– The symbol might be invalid, or no volatility data is available for the requested date. Check the symbol spelling and ensure the date is valid.

• Why does the function sometimes show “Refreshing”?
– If data is currently being updated, you may see “Refreshing.” MarketXLS queues requests to ensure accurate data retrieval. Give it a moment and recalculate.

• Do I always need to include a date?
– No. If you do not specify a date or if the date provided is before 1978, the function fetches the most recently available data.

• Can I input future dates?
– The function will attempt to retrieve data for the provided date, but if no data exists (e.g., a future date), it will likely return “NA.”

By leveraging the ImpliedVolatility90d function, you gain greater insight into an underlying stock’s 90-day implied volatility trend. This can be a powerful component of an overall market analysis or an options trading strategy, all within the familiar interface of Excel.
