I really do not like working with text-based protocols, as they're clumsy, expensive to parse, and take longer to write parsers for.

I'm wondering if there could be a mode added where data will be sent in binary fixed-width structures rather than CSVs. It pains my love for optimization to know that you guys take in binary data, convert it to CSV, and I convert it right back the second I read it.

I know it's probably something that most people do not ask for, but I can't imagine it would take too long for you guys to implement it.

Yes a binary protocol would be better. I suspect that the Windows IQ Feed client probably gets fed binary data but then serves it as ASCII.

Actually a protobuf+gRPC API would be best. Then I don't have to build + maintain decoders for IQ's data protocols.

I agree, IQFeed developers should be able to handle binary protocol just as easily and it should be much more efficient to transfer to clients too. Especially with the hopefully coming soon (?) Market By Order depth protocol this would seem quite desirable to limit the number of bytes sent over the network.

Thank you for your input.

If you haven't already please email support@iqfeed.net with your 6 digit IQ Login ID and that you would like to see Binary Protocol added to the IQ Feed and I will add you to the customer request.

I can verify that the additional Market Depth or MBO is on it's way. Unfortunately I cannot give you an ETA.

Thank you. I have received your request. I will add this to our Customer enhancement for this feature. Please keep in mind our Product Managers review these requests on a monthly basis. If they decide to add this feature I will email all customers that have requested it.

Unfortunately this will be something that requires some development and will not likely not have an ETA initially if we go forward.

Hello guys,

I'm curious, which programming languages are you using ?

Thanks,
Mathieu

I don't think the complexity of a binary protocol is worth it, or adding on an external dependency such as protobuf (and the beast of gRPC) because it is the latest fad.
IQFeed is a simple straight forward protocol is more than ample, and I can literally guarantee that protobuf+grpc overhead will not give any benefit.
