Can you try the Iqlinklancher.exe to start the IQFeed client?
Since it seems like it runs with the Diagnostic ok.

DTN.IQ Client Software Support » Cannot make work Apr 5, 2016 01:11 PM (Total replies: 7)

by shutting off the Firewall you have shut off the controls to the firewall the Firewall systems run in the background.
the best way is to allow the IQconnect.exe through the firewall or make it a exemption in the Zonealarm.

We can help if you can give us a log file with the debug checked. This would help to figure out the exact steps the software takes and what is happening at each step.

Can you log out of the Feed and login with a new connection. We have had sporadic symbol issue and it should be corrected now.

DTN.IQ Client Software Support » Eurex MiniDax Data Jan 27, 2016 07:00 AM (Total replies: 4)

to start with, can you bring up the IQ Watch Quote Application that is installed with the IQFeed Client and enter the symbol DXM# or DXMH16 there?

This is the data coming in to your computer from our servers.
In Sierra Charts, can you do a manual input of the symbol: Go to File and then new Intraday chart, on the file Name: Enter the symbol in capital letters DXM# or DXMH16
I have attached a pdf of the page.

Multi-charts is a very versatile software. It will depend on the actual result you want to see.
From what your describing, It sounds like you will be using tick data to generate the 15 minute data points.
The short answer is ,Yes, you can do this by selecting “use tick data to create minute or Daily charts”.
It will always take the tick data and convert. I do not know if that is exactly what you want to work with. This may be a better question for Multi-charts support.

You will use the Bid/ask to focus in on the very current information of the chart. if you use the trade you can look at a longer time frame.
It will depend on how you set the chart as to the interaction between the Software and the data-feed.
Multi-charts is a very Robust software that can utilize our data-feed to the max.

Data and Content Support » Understanding intraday vs EOD futures data Aug 12, 2015 12:28 PM (Total replies: 2)

Since the e-mini S&P is exclusively a electronic the term RTH may not be correct.
Here is the trading hours from the CME web site in Central time:
Trading Hours MON – FRI: 5:00 p.m. previous day – 4:15 p.m.; trading halt from 3:15 p.m. – 3:30 p.m.

Our data does comes in with an Eastern Time stamp so the time for the data is 18:00 on 1-27-2014 through 17:15 on 1-28-2014 for the daily bar data.
For the intraday data of any minute data you may need to look at the OHLC the same as the daily stamp.

Your logic is correct. We do retain the minute and daily data (the tick would end after 180 days)
