Free historical option prices?

Anyone know of a source for free historical equity option prices? Thanks, Cardshark

I don’t think anybody offers a free service. I’ve looked around before for my personal account to no avail.

It’s a very large data set.

Unlike a single equity, you’re talking about 20 or 30 different strike price contracts (calls & puts) being traded for each expiration month. Tick by tick would produce an enormous amount of data.

you can get a pretty close by backing into it with the vol and stock price.

Cardshark doesn’t have the vols.
