Lets get a thread going on websites you use or know about pertaining to option data. Free or paid subscription. I use finviz.com a lot for their heat map and also scanner. They have a lot of useful stuff for free. I just found this website alphaquery.com ...Its free and offers a ton of data. Anyone else use this website? I was googling "AAPL volatility" and this website popped up. They have data on implied vol, historical vol, and much more, you can customize the timeframe etc. Its a really great site. Please contribute if you have any cool sites. Cheers!
