What discounts are available?

DTN offers a 10%, 20% and 30% discount off our service fees for customers who lock into a quarterly, annual or two year license agreement, respectively. Please contact DTN IQFeed Sales if you are interested in receiving one of these discounts.

Why is my data delayed?

Real-Time data is only available through DTN IQFeed when an exchange has been added to your DTN IQFeed Core Service. If you believe you are subscribed to an exchange but are still seeing delayed data on that exchange, please contact DTN IQFeed Support.

Can I use DTN IQFeed on more than one computer at the same time?

No. While you may install DTN IQFeed on as many computers as you wish, you can only connect with your DTN IQFeed user ID on one computer at a time. If you attempt to connect on a second computer, DTN IQFeed will be disconnected from the first computer.

How fast is the DTN IQFeed?

DTN IQFeed is one of the fastest internet-based data feeds available for the trading markets. Since it runs over the internet, it is to be expected that there will be latency based on your internet bandwidth and the distance the data has to travel. With a good connection, it is not uncommon for a U.S.

What is the API cancellation policy?

The DTN IQFeed API license is an annual agreement. Because the feed is tested and known to work, no refunds will be issued once access has been granted to the developer area. You may cancel your API subscription, but we cannot refund your annual fee.

How do I contact DTN IQFeed Developer Support?

Developer support is reserved for registered developers only. An IQFeed developer can be reached primarily by email (unlimited support) or by chat (limited availability), or by posting in our forums. Note there is no phone support for the API.
