You can use it freely following the link I provided. Or, maybe I haven't understood your question ... ?
Just wonder if we can use it without internet connection. Is there anyway we can link it with real-time data? Or are there similar software with real-time data connection?
If you can handle Excel and Visual Basic (or another programming language), you can do it yourself using an option model. It's pretty simple programming.
cnms2, Thanks. How do you connect your VBA or excel to real-time datafeed? I am using ameritrade, and there is no way to export the real-time data. Which brokers will provide real-time option data with greeks?
You don't need the greeks. The point is that once you know the underlying price, the strike, date, and market price, you can compute everything else including all the greeks.
Thinkorswim, Optionsxpress among others. To connect real-time data feed to excel you need a platform that offers DDL link.
