As you know, the DTN.IQ/IQFeed Core service includes the most comprehensive data available at an unmatched price. In addition to exchange data, our service includes streaming real-time news, over 40,000 DTN calculated market breadth/statistical indicators and 1-minute historical bars going back more than 10 years. As a value-add, we also include dozens of fundamental data fields that provide insight into a stock's corporate actions, trading metrics, and value.

We recently received notice from both the Nasdaq and New York Stock Exchange (NYSE) that they have implemented new fees for the receipt of certain fundamental data fields that are currently included in the DTN.IQ/IQFeed Core service (see below for the fields affected). Because most of our customers find these fields critical to their trade analysis, and to avoid any disruption in the receipt of these fields, we have added a new premium service called “Extended Fundamental Data” to the account of DTN.IQ/IQFeed users. This new add-on service is priced at $5 per month starting October 1, 2017. If you don't require access to these fields you may login to the Account Management Portal at www.iqfeed.net and remove the Extended Fundamental Data service from your account at any time prior to October 1 to avoid the $5 fee and stop receiving these fundamental data fields.

Fundamental Data Fields moving to the new Extended Fundamental Data premium service:


  • Dividend Yield

  • Dividend Amount

  • Dividend Rate

  • Dividend Pay Date

  • Ex-Dividend Date

  • Short Interest

Please note that due to a change in schedule by the exchanges, this change is now scheduled for the weekend of October 1. Please be sure to change your symbols during the weekend of October 1 to ensure you are receiving data October 2.

Vice President, Active Trader Products



In order to improve consistency within our symbology in DTN.IQ and IQFeed, US and Canadian equity warrant symbol formats will be changing effective the weekend of September 16th. The current symbol for warrants will change from having a “+” at the end of the symbol (ie. AIG+), to now ending in “.WS” (ie. AIG.WS). For various classes of stock warrants, the class indicator will follow the “.WS” (ie. BAC.WS.A or BAC.WS.B instead of the current symbols of BAC+A or BAC+B).

If you are watching any warrants from US or Canadian markets, please be sure to change your symbols during the weekend of September 16th to continue receiving data. If you have any questions, please contact our support group at 800-779-7299, support@iqfeed.net or chat with us by visiting our website at www.iqfeed.net.

Some additional Examples of the symbol changes:
US Equity Warrants:
DYN+ --> DYN.WS
DYN+A --> DYN.WS.A
JPM+ --> JPM.WS

Canadian Equity Warrants:
C.NDM+ --> C.NDM.WS
C.NDM+A --> C.NDM.WS.A
C.NDM+B --> C.NDM.WS.B

Based on customer feedback, effective this evening we will be changing the roll rule for @GF (Feeder Cattle) contracts to roll 2 weeks prior to expiration. This will provide continuation chart data that will more closely follow volume/OI on this contract.

A cross platform version of IQFeed continues to be on the roadmap. IQFeed will continue to be a GUI based product however as the exchanges continue to tighten their fee structure around non-display applications. While there are users who would like to build non-display applications off our service, you would be required to pay thousands of dollars per month to the exchanges for the privilege. Unless the exchanges change their tune and create more trader friendly fee structures, our plan is to continue providing our display applications in order to provide service to a broader audience.

Yes we do. It is now called "Live briefs Pro Global Markets". Because we now have more global markets such as London Stocks, we upgraded our users to the global feed from MT Newswires.

Our engineers are looking into this. It appears a login server is having issues.

Unfortunately you can't. Your data subscription has a symbol limit and we don't allow users to systematically/programatically scan the market by watching and unwatching symbols. If you need a full market feed, please take a look at our NxCore service at www.nanex.net.

IQFeed Developer Support » forex: last always == bid? Apr 16, 2017 09:02 AM (Total replies: 5)

The field "Last", or "Last Trade Price" is always equal to the bid with forex data since forex is a quote only (bid/ask) feed (doesn't report actual trades). IQFeed uses the Last field for historical data. Thus, the historical data is derived from the Bid field.

Hey Tony,

You will need the CME S&P Global Indexes (SPG1200.X) and the Dow Jones Indexes (GDOW.X) as those indexes are fee liable regardless of delay. Thus, by adding the service the data will be in real-time.

IQFeed Developer Support » the fly on the wall news Mar 28, 2017 09:44 AM (Total replies: 1)

Yes, the news within IQFeed is available as part of the API.

Jay Froscheiser
Vice President, Active Trader Products



We provide a professional level of service to our customers as you see by the fast response to your inquiry. It appears you have already tried to hack your way toward using IQFeed in your application, which may be good enough for some of our users. There is no additional cost to doing this other than time and frustration. The level of support we provide to developers is unmatched and is provided for those who can't afford for their software to stop working because they took shortcuts or weren't aware of changes made to the API that could break their code. The API service includes full documentation, sample code, direct support from our development team, notification of changes, and access to pre-production systems or beta versions to allow you time to test your software before we release to the general public. At $360 per year, this should be one of the smallest investments you can make into your trading system.

There is cheap and free data out there. Many have come and gone over the years because they either provided poor service or had a bad financial model. Providing quality service is neither cheap nor easy.

We would love the opportunity to serve your needs and help ensure you have a trading system that will be operational for years to come.

Thanks everyone for posting your suggestions and feedback. While we won't be providing a non-GUI version of DTN IQFeed, we do have plans to make IQFeed run more easily in cross platform environments. It's in the early stages at this time but is on our Roadmap.

We received your follow up email as well and a response is coming shortly. For those on this forum with the same question, I will also answer here:

We store tick data for 180 days. This data can be retrieved in nVolume, nTick or nSecond intervals where “n” is whatever interval you choose. We store many years of 1 minute data. This data can be retrieved in nMinute intervals. Thus, you can request 60 minute bars and you will get data up to the latest tick with the last bar being a partial bar.

We store daily data with bars generated at the end of each day. When you ask for weekly or monthly bars, we derive that from the daily bars. These intervals will not include the current day's trading session until the end of the day. Our customers are traders, and thus they are nearly always also watching a stream of the instruments they are interested in. The stream includes everything they need to create their own partial/current bar for the day/session including OHLCV.

You don't need to hand crank over a load of data. You just need to watch the stream on the symbol. When you watch a symbol we send the current session OHLCV immediately and update it with every tick throughout the session so your chart/analysis can stay current.

Bob, we don't have any plans to provide a bundled/summary feed. Our customers overwhelmingly prefer the fact that we unbundle the information provided in the MDP 3 protocol.

We are however working to bring additional information to our customers that will give them more insight into the makeup of trades. This includes Tag 346 as well as a few others. I don't have timing for when this will be made available, but it is on our roadmap and will be implemented along with other enhancements we are working on for IQFeed.

Right now, a user can determine trades that we unbundled from the exchange by looking at the TickID field as all trades that we unbundled will have the same TickID.
