"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed.

For C#, you should definitely take a look at
It deals with the TCP sockets and works great.


Data Questions » options Complex Order Books? Nov 17, 2021 08:01 PM (Total replies: 12)

I've been curious about this too. I think the original question was not about executed trades, but about bids/asks at different price levels on the regional options exchanges. The closest I can find on the available DTN subscriptions is the NASDAQ Level II (OpenView) subscription. "This includes the best bid/ask (top of book) from each MMID for NASDAQ and listed stocks)." It doesn't mention options or regional option exchanges, whether top-of-book, or complete-book. It sounds kind of like "NBBO" but broken down by MMID. Top-of Book implies that there is no depth-of-book info (i.e. bid size/ask size at price levels that are above/below BBO price). Just hoping for any clarification available. Much appreciated.


Thank You!


Does this request use real-time price data on the underlying when determining In/Out Of The Money contracts?
If not, can you let us know where/when the underlying price comes from? Thanks!
