backtesting options?

I'm trying to do a "rough" backtest of a QQQQ options strategy. Is there a way to get options pricing data from several month ago? thanks.

 

Some links/sites from few months back (from ET forum):

Are you just looking for freebies, or do you want to pay for the service?

 

Was hoping for a freebie (of course) but would pay if needed.

 

www.thinkorswim.com

register and use the desktop software

use their 'thinkback' feature

 

Optionetic's Platinum has it very nicely. http://www.optionetics.com/
good luck

 

Curious - what software are you using?

Commercial or proprietary?

I've looked at almost all software for backtesting options and
none offers genuine backteting.

Try these sites below. I suggest you pay a vendor so that
you get good clean data. It's worth it.
