"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

IQFeed Developer Support » chronological order of ticks received? Apr 19, 2018 04:34 AM (Total replies: 1)

Am I safe with the assumption that the messages I receive for one symbol will be in chronological order, or do I need to code for the possibility that an exchange or IQFEED may send a tick out of chronological order occasionally?

Particularly, if my requests are

S,SELECT UPDATE FIELDS,Symbol,Most Recent Trade,Most Recent Trade Time
t@ES#

Will Most Recent Trade always be the most recent? Or do I need to use CPU checking its timestamp against the previous tick's timestamp?

Data and Content Support » Can't Connect via iqconnect.exe Apr 19, 2018 12:04 AM (Total replies: 10)

I ran into this same problem. Found this thread in a search. I fixed my problem already, but for anyone just starting out with the API:

the example on http://www.iqfeed.net/dev/api/docs/docs52/InitializingTheFeed.cfm has small typo so can't copy/paste it into your code and replace with your parameters

IQConnect.exe ?product YOUR_PRODUCT_HERE?version 1.0.0.0 ?login 100000 ?password 1234 ?autoconnect

It is missing a space between YOUR_PRODUCT_HERE and -version. Once I fixed that it works.

Makes sense. Thanks.

IQFeed Developer Support » C# sample program for Leve1Socket Apr 4, 2018 08:55 PM (Total replies: 5)

I've found all of the sample C# programs very helpful and the comments make for easy following. I have one question about the Level1Socket program.

In Level1SocketForm.cs, lines 201-202 are:

 
// move on to the next message. This isn't very efficient but it is simple (which is the focus of this example).
sData = sData.Substring(sLine.Length + 1);


Do you have any examples showing more efficient ways? If not, can you please point me towards a better solution. Thank you.

IQFeed Developer Support » How are derivative bars built? Mar 15, 2018 04:57 AM (Total replies: 1)

I have a few technical questions regarding derivative bars in IQfeed. Apologies if I missed this information in the documentation, but I could not find it.

1. Lets say I have requested streaming bars with an interval of 60 seconds. In the messages my client receive, what will [DateTime] represent? Will it be the start time of the interval or the end time of the interval? E.g. Would 12:00:00 be for interval 2:00:00 to 12:00:59, or interval 11:59:01 to 12:00:00?

2. Within IQFeed, what determines when a bar is "finished" being built and sent out to my client? Is it my internal computer clock, IQfeed's server clock, or timestamps on ticks? If it is timestamps of ticks, then I suppose the bar won't be sent to the client until a tick with timestamp OUTSIDE that interval has arrived. That could cause delays in instruments with low volume.
