Options and Equity Quality Data

[lampost]

Where is the best site to source Options and Equity data along with Volumes.

- I have tried Google but the Volume isn't accurate.
-Where would be the best place to source intraday data, 15mins interval?

Thanks

1st stop should be your broker, as it is typically free. There are paid services;-- for SPX I like CBOE Livevol.

You can get options charts and data from www.interactivebrokers.com.

What about historical data for back testing

Interactive brokers offer options history as as well as EOD/intraday history via API for free.

I use Quandl extensively for all my end of day stuff. They have some data sets for options and futures that I find really helpful and have reduced my workload in terms of processing data. For intraday I use InteractiveBrokers.

About a decade ago, I used to buy from deltaneutral.com and eoddata.com. One of them stopped providing bid and ask numbers for US equity options, only providing open, high, low, and close. I hope that that problem has been fixed since then.
