Where can I read or download the socket interface documentation?

I searched the IQfeed, but only found the quick start guide which wasn't really helpful
I intend to use it under Wine / Linux, so if anyone can also share examples in Perl or Ruby, that would be great too, as I will also be learning socket programming as I go

From what I collected online, I believe I will connect to a socket on the loopback IP 127.0.0.1 and port 5009.

And that I should be able to send messages to query the feed, so I believe the documentation should include the message formats like how to specify a symbol or symbol list, a date range, how to request for delayed vs historical vs real time, does this detailed documentation exist somewhere?

Thanks,
AMS

The full documentation is only available to registered developers. The IQFeed API service is $300 per year and includes sample applications/source-code, full documentation, direct support from our developers and early access to upgrades for testing (to ensure changes we make doesn't break your application).

I will say that if you are learning socket programming, IQFeed may not be a good place to start. Processing thousands of messages per second off a socket isn't trivial. In order to write applications to IQFeed, we recommend that you are proficient in socket and multi threaded application programming.

Thanks Jay for your prompt reply.

I just installed IQfeed under Wine/Linux, it seem to work, I was able to

> telnet localhost 5009

which i took as a good sign, it keeps sending records that look like this thought

I am not sure what this mean.
I hope I didn't break anything! If you can explain this please do

The next step for me would be to buy the developer registration to receive the full docs, I think I would need anyway no matter which route I decide to go

thanks again.

You definitely need to register for the developer docs. What you are seeing is the regular time stamp from the client. So, what you are seeing is a good thing... you have a good connection.
