If you have a TD Ameritrade account you can use US market streaming quotes and option chains from TD Ameritrade:

	with the Hoadley Options Strategy Analysis applications
	in your own Excel spreadsheets.

The Options Strategy Evaluation Tool will retrieve live US equity and index Options Chain shapshots from TD Ameritrade for advanced analysis of options strategies, including strategy comparisons, probability of profit analysis, ROI, position hedging, early exercise analysis and much more.

The Implied Volatility Calculator will use TD Ameritrade option chains for monthly volatility smile/skew analysis, implied volatility surface analysis including 3D volatility surface graphing, valuation analysis and hedging optimization.
 

The Hoadley Finance Add-in for Excel contains a function to connect your own spreadsheets directly to the TD Ameritrade streamer. 

The quotes are fully streaming -- no refresh required -- and the quote functions  can be used in your spreadsheets in exactly the same way as you would use any of the normal Excel functions (SUM, AVERAGE, NPV...).

The add-in also includes a component, for use in a VBA module, for bringing live option chains into your own spreadsheets for analysis.

Unlike most common streaming quote solutions, the Hoadley Finance Add-in for Excel does not use Microsoft's obsolete DDE technology for bringing quotes into spreadsheets.  Instead it uses the newer RTD (Real-Time Data) technology developed by Microsoft to replace DDE. 

RTD is much more robust and flexible than DDE.  For instance, with DDE you need to "hard-code" symbols and field names in your spreadsheet formulas.  The Hoadley Finance Add-in for Excel on the other hand does not require the "hard coding" of symbols and field names in formulas. It therefore provides much more power, flexibility and ease of use compared with conventional DDE solutions.

A function Wizard in the Finance Add-in for Excel guides you through the simple process of inserting streaming quotes into your own spreadsheet cells. No programming is required and the add-in includes sample worksheets containing examples using TD Ameritrade data.

This combination of the Finance Add-in for Excel plus live data from TD Ameritrade provides a powerful analysis platform for traders.  You can use the power of Excel with the Hoadley Finance Add-in to look behind market data to gain a much deeper understanding of option pricing, volatility, probabilities, and hedging.
 

Microsoft Excel version 2002 (office XP) or above running under Microsoft Windows.  Earlier versions of Excel cannot be used as the real-time data technology (RTD)  required for a robust streaming service was first released in Excel 2002.
