IQFeed Developer Support » Code Changes for CME MDP 3.0 protocol Aug 12, 2015 10:06 PM (Total replies: 0)

I am trying to understand the code changes in C++ I will need to make to keep using the IQFeed. From what I read in the DTN Forums the changes effect the items TickID and "Message Contents" which are part of the Level1 Port System Messages. Is there a document describing the code changes we need to make when processing these values after August 23?

Message Contents
C - Last Qualified Trade.
E - Extended Trade = Form T trade.
O - Other Trade = Any trade not accounted for by C or E.
b - A bid update occurred.
a - An ask update occurred.
o - An Open occurred.
h - A High occurred.
l - A Low occurred.
c - A Close occurred.
s - A Settlement occurred.

The CME Group ends pit trading on July 2, 2015. Is there a DTN notice how the symbols will change. I guess only Globex symbols from now on.

Dear Eric,

I posted the original message. The problem I had was caused by multiple computers using the same wireless internet connection. When I disconnected all computer but the one I was using DTN with and the login did not hang.

I see there is a new version iqfeed_client_5_1_3_1 which may solve a problem you had with

Good luck

IQFeed Developer Support » web page to update developer information May 6, 2015 12:34 PM (Total replies: 1)

The link below is not working for the web page to update developer information. Is this a temporary problem or is there a new web page to update dev information.

500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.

I am experiencing a new login problem that started in the past few days. The login has been working and I am doing the final testing for my application. The login still works on my Windows 8 test computer but does not work on the Windows 7 test computer.

My application is using the socket connection to DTN created by calling iqconnect.exe. I am using IQFeed Version, The iqconnect.exe shows the message Retrieving IP information and pauses, never moving past this point.

Below is my log file named: IQConnectLog.txt I see the items LookupError,L2Error,L1Error in the log file but I am not sure what this means. Can you suggest a solution?

IQFeed Developer Support » Help With History Request Time Stamps Jan 29, 2015 01:26 AM (Total replies: 3)

Dear Steve S.

I believe I understand your answer. Let me ask about the first time stamp of the day 00:00:00. Based on your answer 00:00:00 is actually the last data set for the previous day. Is this correct? In the example below, 2015-01-29 00:00:00 is the last data for 2015-01-28. Is this correct?

60 minute data
2015-01-29 02:00:00 = (01:00:00 - 01:59:59)
2015-01-29 01:00:00 = (00:00:00 - 00:59:59)

2015-01-29 00:00:00 = (23:00:00 - 23:59:59 Previous day 2015-01-28)

2015-01-28 23:00:00 = (22:00:00 - 22:59:59)
2015-01-28 22:00:00 = (21:00:00 - 21:59:59)


IQFeed Developer Support » Help With History Request Time Stamps Jan 28, 2015 09:54 PM (Total replies: 3)

It was my understanding the time stamps on a history requests for the S&P500 mini futures contract symbol ES were the time periods Opening Time in East Coast Time. The Level 1 time stamp was also East Coast Time. My Problem is that the newest record returned from a 60 minute history request seems to have a time stamp that is 1 hour ahead.

Here is a real situation:

At 8:47pm ET (20:47:00) I request 60 minuet data for @ESH15

The most current data point I get back has a time stamp of 21:00:00 which is 9:00pm ET. The three newest time stamps for this 60 min data request are below.
2015-01-28 21:00:00
2015-01-28 20:00:00
2015-01-28 19:00:00

I am using the 10 minute delay data for @ESH15 so my Level 1 time stamp is 20:37:28:646 which is 8pm 37min 28sec 646milsec.

My problem is the newest data from the history request has a 21 (9pm) time stamp. How can I get a 21(9pm) time stamp before 9pm?

I seem to have misunderstood what a Synthentic contract is. Below are three soybean Synthentic but they do not seem to return much data and I am not sure what the data is. Can you explain what a Synthentic item is?




I am trying to find the symbol that will call a continuous futures contract that rolls to the same contract month. For example a symbol for November Soybean that rolls from Nov12-Nov13-Nov14-Nov15 always rolling into the next November contract. Is the symbol below the correct symbol for this?

Continuous November Contract rollover?

IQFeed Developer Support » How to Get the Previous Day's Close Nov 18, 2014 02:12 PM (Total replies: 1)

I am accessing the DTN IQfeed through a Socket.

I am looking for the recommended way to get the previous day's closing price that is used to calculate the Change and Percent Change values.

I have been looking at the Fundamental Messages and Update/Summery Messages and Level1 Messages but I don't see anything called previous close.
