I want intraday real-time data for entire option chains in a format that's easily downloadable (so I can get it into Excel.) There are obviously plenty of data providers that sell end-of-day files of historical data, but as for real-time / intraday quotes, I can't quite find it. I currently use the IB API to stream data into Excel, but I'm that amt of data I want to import (quotes for entire option chains for perhaps 100 underlyings) quickly overwhelms Excel / their API. But if I could download CSV's of real-time data, it would be much easier to run a script to pull them all into Excel as hardcoded values. Obviously a downloaded file would only be a *snapshot* of the quotes at any given time (rather than updating/streaming), but that would be fine for my purposes. I just can't seem to find providers who offer this kind of real-time data that's easily downloadable.
