"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

"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
"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat
"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 cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles

IQFeed Developer Support » Do not hide to system tray Jan 13, 2022 04:24 PM (Total replies: 1)

I ended up switching from fluxbox to twm as a window manager. Wine is able to emulate windows system tray in twm. Problem solved.

IQFeed Developer Support » Do not hide to system tray Jan 12, 2022 08:04 AM (Total replies: 1)

Hi,

I'm running iqconnect.exe on Linux using wine. Is there a way to prevent iqconnect.exe from minimizing to Windows system tray upon startup as my window manager does not have system tray and as a result I don't have any visual indication that iqconnect is running?

Thank you

Thank you for a reply, super helpful. Talking about "data must be received and consumed on the same machine" clause. Does it apply to the physical machines or to virtual machines as well? If I run iqfeed on the Windows VM, running on linux, and connect to its socket from the host machine, does it still violate the agreement?

IQFeed Developer Support » API questions Nov 9, 2021 01:04 PM (Total replies: 2)

Hi,

I'm considering becoming an iqfeed customer. To make this decision, I have to close on a few open questions.

I have a trading system which needs tick-by-tick trades stream for NASDAQ e-mini futures to operate.

Questions:
- My trading systems runs on Linux. I don't want to use wine. Can I run iqfeed on a separate machine (under Windows) and connect to its sockets over the LAN? Does iqfeed listen on all IP addresses or only on the localhost (and therefore will require running some bridge / proxy to make it available outside of localhost)?
- In case something bad happens (iqfeed crashes, network disconnects), is it possible to recover the tick-by-tick stream using historical data during the trading hours? Let's say my app has identified there is a gap in real-time data between 10:00am and 10:05am. Will I be able to request historical data between 10:00am and 10:05am to backfill (and do it during regular trading hours such that once backfill is over I could proceed with business as usual)?
- As a follow-up to the previous question. Does iqfeed provide some unique tick identifier (IIRC, CME has them) such that during backfill I could easily distinguish between ticks I have received already through real-time stream and those which I haven't?

Thanks
