Are you able to replicate this your end? Basically the level 1 feed is not providing millisecond data. Many thanks.

Hi Steve - no the response I get is the one posted above, for the particular symbol I specified.

What I am doing is no more than asking for data back from IQ Feed like so:

CString csCommand = "S, SET PROTOCOL, 5.1\r\n";

This is immediately followed by a call to SendRequestToIQFeed, passing csCommand.

csCommand.Format("w%s\r\n", m_csRequestedData);

This is also immediately followed by a call to SendRequestToIQFeed, passing csCommand.

csCommand = "S,REQUEST ALL UPDATE FIELDNAMES\r\n";

This is also immediately followed by a call to SendRequestToIQFeed, passing csCommand.

The SendRequestToIQFeed function which contains:

void CDataEngine::SendRequestToIQFeed(CString csCommand)
{
int iSentBytes = m_IQConnectSocket.Send(csCommand, csCommand.GetLength());
m_lstData1.InsertItem(0, "Successfully connected to IQFeed.");
if (iSentBytes != csCommand.GetLength())
{
m_lstData1.InsertItem(1, "Unable to send Request to IQFeed.");
}
}

Hello Tim,

Can I check if there are differences between MSFT and @ESH15? If I ask the IQ Feed connector what it can give me in terms of fieldsets, after setting the symbol, it reports as below. None of which relate to millisecond precision. Can you test your end and suggest any enlightenment?:

E,Last TimeMS is not a valid fieldset field.,

DTN.IQ Client Software Support » No millisecond resolution data Feb 10, 2015 01:30 PM (Total replies: 7)

The marketing material says that millisecond data is available, but when the following request is sent to DTN IQ Feed 5.0 for the symbol @ESH15:

S,SET PROTOCOL,5.0\r\n
S,SELECT UPDATE FIELDS,Symbol,Last,Last Trade Time,Bid TimeMS\r\n

Instead of getting update messages with millisecond accuracy, IQ Feed replies:

"Bid TimeMS is not a valid fieldset field."

The legacy IQ Feed 4.9 field: "Last Trade Time" is only accurate to the nearest second.

Am I missing something? Why are the documented version 5.0 fields not available? Thanks.

DTNIQ Client Software Wish List » Dynamic Fieldsets for Level 2 Data Feb 4, 2015 12:34 PM (Total replies: 0)

Wish it were possible to configure Dynamic Fieldsets for Level 2 data just like you can with Level 1 data.

Reasons:

1. Level 2 data is highly frequent.
2. Level 2 data lines can be somewhat verbose.
3. Can save DTN IQ on bandwidth and processing costs.

Thanks for considering it.
