Can anyone provide how to get the data of historical options with hits of the Google Finance API? Mbe Yahoo API can do this? Thanks.
AFAIK, there is no free API that makes it easy to request historical option prices.
It’s best to collect it daily for the promotions you’re interested in: http://www.google.com/finance/option_chain?q=AAPL&output=json
I have never seen free pricing data on historical options. Neither Yahoo nor Google provides them. I downloaded data at the end of the day to day from optiondata.net. It includes daily prices, Greeks and IV. As far as I can tell, this seems accurate. There are several paid sources, but I did not check their data.
