I've been using IqFeed for several years to get end-of-day option data along with quotes, dividend info, and split info for optionable stocks. I absolutely need end-of-day data and being able to monitor the market in real-time is desirable, but not required at this point. The reliability of the IqFeed for downloading approximately 300,000 items a day in chunks of 500 (due to the symbol limit) along with the format of the data, and stability of the API leaves a lot to be desired.

Is there a better product available for EOD option data?
