"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

IQFeed Developer Support » SELECT UPDATE FIELD return value question Jul 5, 2016 02:14 AM (Total replies: 8)

Hi Tim,

thanks for your reply. As per the following description:

Field Name = Tick
Field Type = integer
Field Description = Direction of change from last Trade
Origin of Data = Calculated by IQConnect.exe based upon previous trade

Depending on the I consistently get 3 integer values of:


After examining a log file of the output it appears the values have the following meaning:

173 = price was higher than the previous price;
175 = price was lower than the previous price;
183 = price was the same as the previous price;

Is this correct?

when I issue a "S,SELECT UPDATE FIELDS,Symbol,Last,Most Recent Trade Time,Most Recent Trade Date,Ask,Bid,Spread,Tick\r\n" command in a WATCH (forex data) request, the Tick field value is returned as an integer. Subsequently, I have the following question:

1. What integer values are expected to be returned for the Tick field?

Thanks in advance

It turns out that the customer did not have an uptodate subscription to streaming data for the new machine!!!

IQFeed Developer Support » Symbol not found - Visual Studio 2010 Jul 15, 2014 05:43 AM (Total replies: 2)


I compiled the example Level1Socket example using Visual Studio 2010 Ultimate (which is up todate) on an Asus laptop running Windows 8 and I get 'Symbol not found' message when I submit a watch symbol command.

The asus is a G750JX i7 2.4GHz with 16GB of DD3 RAM and SSD

It works when compiled on an Asus laptop running Windows 7. Is anyone else experiencing this problem?

If I request records such as 5 min bars on the Asus running Windows 8 I do not get an error and bars are updated correctly.

Thanks in advance

IQFeed Developer Support » Protocol 5.1 - Invalid Symbol Apr 3, 2014 08:18 PM (Total replies: 2)

the simple solution to this problem was to add a TrimRight() to the symbol string before formatting the

CString csCommand(m_csUserData);
if (m_csUserData == csCommand)
// add this line

csCommand.Format("w%s\r\n", m_csUserData);
m_IQConnectSocket.Send(csCommand, csCommand.GetLength());

IQFeed Developer Support » Protocol 5.1 - Invalid Symbol Apr 2, 2014 10:19 PM (Total replies: 2)

I compiled the sample LevelOne app using MSVC 2008 on both Windows 7 and Windows 8 OS and if I don't use Protocol 5.0 or 5.1 and request GBPUSD.FXCM as a watch I get the correct data and fields as requested. If I use Protocol 5.0 or 5.1 I get an invalid symbol message. Is there something I am missing here...see attached image...thanks in advance

Hi Steve,

as for the machine, I am running Asus i7 processor with 16GB RAM and 2 x SSD's while watching only 4 symbols. The heartbeat actually stops so the problem could be internet related at either end but having said that I run an app to check time against the atomic clocks and it is unaffected.

The heartbeat problem is can go for days without problem and then stop several times in a session.

My app shows approx. 22 MB as working set memory and 8 MB private working set memory so it is not exactly placing a huge demand on the available RAM,

I also get random failures with the heartbeat message. I added a check to measure the delay against the PC clocks. If the delay is > 30 secs I display a dialog to let the user know while at the same time switching off the connections and feed which at least prevents crashes but it does require a restart.
