Nasdaq has notified us that they are having issues disseminating quotes or trade reports in Nasdaq listed securities..

Our customers like the Realtimetraders news that is included in the basic service of our DTN.IQ, IQFeed and ProphetX Active Trader services, but many also buy theflyonthewall or Midnight Trader for pre and post market information. All of these services are available for purchase direct from the...

Can you elaborate on your statement that there is no technical help available? We have 800# support (800-532-0136), email support with < 1 hour response time (prophetx@dtn.com), and forums (http://forums.dtn.com). ProphetX documentation is available at...

If you have a DTN.IQ subscription feeding Ensign ($59/month with annual subscription), you can run the DTN.IQ software along side Ensign (at no extra charge) and get close to what you are looking for. In the DTN.IQ T&S app, there are tick marks "<<" next to the bid or the ask if the trade was...

The CBOE has informed vendors that the VIX is not being calculated or disseminated. This issue is being investigated by the CBOE and no timeframe was given for its resolution. Jay

Yes, it is for historical data only. We have on our project list the push of minute bars to the client, but as of yet it hasn't been assigned a priority. Once we clear the plate with our next server release currently scheduled for April, we will begin to evaluate the projects. I think this...

We do it as you request already (except we also return Volume in the record). I'm not sure what software you interface us with, but we support (x)Minute requests, build the data into that interval on the server, and return it to the client that way. If you want 109 minute bars, you will get...

You are correct with DDE. However, we were looking at 1800 symbols using a couple 3rd party apps (QuoteIN and XLQ) which run off IQFeed and utilize RTD to feed Excel instead of DDE. Running 1800 symbols is obviously a strain with the amount of data being processed (by IQFeed, 3rd party app...

IQFeed can feed AmiBroker and QT at the same time as long as you have an IQFeed for AmiBroker subscription (www.iqfeed.net/amibroker). Plus, I talked to Tomasz yesterday, and he will be releasing a new IQFeed plugin that will remove the hard coding to our old 120 calendar day minute data limit...

They must have it hard coded to the previous limit of 120 days. For @ES#, you should be getting data back to 5/11/05. I will contact Tomasz and see if it is something in AmiBroker limiting the history. Jay

Thanks for the comment about our service. In case you missed our announcement today, we increased the intraday (minute) data available on IQFeed from 120 Calendar days to over 8 months. On the Emini contracts (@ES#, @NQ#, @YM#, etc), we have as much as 1.5 years of minute data now available...

We actually just announced today that we now provide approx. 1.5 years of minute data on the most highly traded Emini contracts. We also increased the amount of minute data for all other symbols from 120 calendar days to over 8 months of data. Some 3rd party software had built in the limit of...

The only data we get from Reuters is some of our International futures data. All US Futures and Equities is direct from the exchanges.

Since you are running QuoteTracker, you should look at the number under the "Start/Stop" button. QT will queue data if it can't process it fast enough, and this would explain the bursting of data. Jay

on AMG, those bad trades were cancelled by the exchange, but unfortunately we don't have tick correct being processed in our IQFeed product yet. Our ProphetX Active Trader does process the tick corrections, so these spikes don't affect the charts or other analytics. Tick correction is coming...

VWAP is a field within the software/Feed, so there is no need to program it to display in a Quote Sheet of via DDE in Excel. If you are wanting to calculate data for display in the quote sheet or charts, you can use free form functions such as a+b+c+d/e for example. You can also use the...

You folks (and our support group) are correct that we don't filter the data within IQFeed. Some people appreciate it, while others would prefer we filter. One of the main reasons for not filtering is we prefer to leave it up to the software interface to implement the filtering. This allows...

DDE is an older technology, although it is nearly a standard for market data applications. DDE is mainly limited to the number of "conversations". The definition of a "conversation" varies by provider and how they wrote their DDE server, but in the case of DTN IQFeed a conversation is a field...

Not at all. I have been in communication with Jerry regarding the changes, and things are as good as ever between DTN, QuoteTracker, and TD Ameritrade (who was already a large client of DTN). IQFeed is one of the smallest businesses of DTN. While it is a great business, we have many more...
