"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam
"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
"Can I get another account from you? I am tired of ******* going down so often" - Comment from George

IQFeed for Mac Installation


NOTICE: The Apple Catalina operating system supports 64-bit programs only. Currently, IQFeed is 32-bit, so it will not run under Catalina. We are working on a 64-bit version of IQFeed to overcome this limitation. The instructions below are for Mac OSX version Mojave and older.

Overview

IQFeed is a windows application. As a result, we (DTN) utilize a 3rd party application called Wine to run our Windows application on Mac OS X.

On previous IQFeed versions, through 6.0.0.5, we used a package manager called Winebottler to package Wine and IQFeed into a single, standard Mac OS X installation. Due to conditions outside of our control, this package manager no longer works for our installations. Rather than delay IQFeed development while searching for a new Mac OS X installation, we are temporarily offering manual installation instructions.

We realize this is a less convenient approach, and we are currently working towards having an integrated installer again. If you run into any issues or would like help walking through this installation, please contact our Technical Support using the chat link to the left or call our support hotline.

Prerequisites

  • MacOSX Snow Leopard (10.6.3) or later, excluding Catalina.
  • XQuartz 2.7.11 or newer - This is required by Wine.
  • Wine (any version, but we recommend 4.0 or newer).

If you have already installed any of these, there is no need to re-install them (skip those sections). If you do not have them, follow the instructions below to install:

Before Starting

Before beginning this process, be aware of the following:

  • You must be on a Mac OS version earlier than Catalina.
  • You should uninstall any previous versions of IQFeed. If you installed IQFeed 6.0.0.5 or earlier using WineBottler via download from iqfeed.net, this should be uninstalled before proceeding with the below instructions.
    • If you have any saved Watchlists in IQFeed, they can be brought over to the new location. Watchlists are saved in .WAT files. Just navigate to wherever the .WAT files are saved and put them in a safe location. Then, after the new install is complete, you can open the watch files from that location, or move them wherever you want to store them. DO NOT SKIP THIS STEP. If you are unsure, please contact our support group BEFORE uninstalling the previous version of IQFeed.
  • MotiveWave users will need to manually launch IQFeed before entering MotiveWave. The MotiveWave functionality to automatically launch the feed will not work properly. If you follow the steps in the Installing IQFeed section below, you will end up with an icon on your desktop that can be used to launch IQFeed for this purpose.
    Once we again have a integrated solution we will work with MotiveWave developers to streamline this process once again.

Installing XQuartz

  1. Go to The XQuartz Homepage.
  2. Download latest .DMG file.
  3. In your browser's download area or the Downloads folder, double-click the .DMG file.
  4. Double-click XQuartz.pkg to begin the installation.
  5. Follow the prompts in the install program. Grant any permission that is requested.
  6. You may get a message "you must log out and back in to make Quartz your X11 server." Disregard this message.

Installing Wine

  1. Go to The Wine Downloads page on winehq.org.
  2. Click Wine Builds, then macosx, then download.
  3. Click Installer For Wine Stable link at the top. This will download a .PKG file to your system.
  4. Double-click the .PKG file to begin the installation.
  5. Follow the prompts in the install program. Grant any permission that is requested.
    1. You may get messages that wine-mono and Gecko packages are missing. Install them.
    2. Use the "Install For All Users" option, unless you have a specific reason for doing otherwise.
    3. 64 bit support for Wine is not currently needed for IQFeed. This option can be left unchecked, unless you plan to use Wine to run other Windows software.

Installing IQFeed

If you are installing IQFeed under Wine for the first time, follow the below steps:

  1. Go to The IQFeed Download page and click Download to download the latest .EXE file.
  2. Double click the .EXE file.
  3. A Windows-style install process will begin. Follow the prompts and accept all defaults.
  4. Cleanup. Unfortunately, the windows installer for IQFeed creates a bunch of icons on your MacOSX desktop that won't work for you. Here is how you clean them up and replace them with usable ones:
    1. Delete the 9 new icons on your desktop with generic icons by dragging each one to the trash.
    2. Open Finder.
    3. Click Documents.
    4. Navigate to the MacintoshHD location. Depending upon your settings, you can get there through ⌘H (home) or ⌘↑ (up one folder).
    5. Click your user.
    6. Press ⌘ + Shift + . to view hidden files. A folder called .wine will appear:
    7. Open the .wine folder, then drive_c, then Program Files, then DTN, then IQFeed.
    8. Right-click IQSnapQuote.exe.
    9. Select Make Alias. A copy of the wine glass icon, with a small arrow and the name "alias", will appear:
    10. Left-click the alias, and drag it to the Desktop, or wherever you want to store it.
    11. Repeat steps h-j for all the icons you want to create.
      NOTE: A single icon will allow you to launch the feed and is all that is required. You can access each of the other apps from within the first one you launch.

FAQ

Q. What is Wine?

A. Wine is a technology that lets you run Windows programs within macOS. More technically, the makers of Wine describe it as "a compatibility layer capable of running Windows applications on POSIX-compliant operating systems", which includes macOS. For more information, see their website at winehq.org.

Q. Why do I need to install Wine to run IQFeed?

A. Unfortunately, DTN can no longer offer the WineBottler install of IQFeed. To make IQFeed work on a macOS operating system, you must install Wine, and run IQFeed under Wine.

Q. Why do I need to install XQuartz?

A. It is a pre-requisite of Wine.

Q. I already have XQuartz and/or Wine, do I need to install them again? Do I need to install them each time IQFeed releases a new version?

A. No. But it is advisable to ensure you are on the latest version of XQuartz/Wine, and update if necessary.

Q. I have the Windows operating system installed on my Mac under Boot Camp. Do I need to install Wine?

A. No. You may download, install, and run IQFeed under Windows. The installation process is the same as for any Windows computer.

Q. I use something other than Wine (e.g., Crossover) to run Windows programs under MacOS. Can I use that instead?

A. Yes, but DTN can only provide limited support if it doesn't work.
