I use PolygonIO live stream to get all trades over all options, including SPX ones But, I see nothing coming before market opens whereas CBOE is trading it almost 24h a day (https://go.cboe.com/24x5) @PolygonIO: Is there a way to have SPX on extended hours? Do you know any data provider for such live feed (trades, quotes)? Regards.
Hello, We offer SPX options during global trading hours. I noticed in another thread that you are interested in Level 2, Indices and Futures, which is also something we can provide. You can learn more about our solutions here: https://www.nxcoredata.com/ If you would like more specifics about our feeds, please reach out to us at sales@nanex.net
