"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 would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"You have an excellent product !!!!!!" - Comment from Arely
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"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
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"You have an excellent feed. Very few spikes for Spot Forex." - Comment from Public Forum Post
"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles
"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

Data and Content Support » IQFeed Change To Simultaneous Requests (sudden "E,Too Many Connections" errors) Jan 20, 2021 05:20 AM (Total replies: 13)

That's strange. I believe your limit is a little bit behind 50 requests per second. I mean it should be less than 50 not equal to 50. My code has been well tested and I'm using high precision timers in order to throttle the output and using 50 triggers the exception. Received confirmation from others that adjusting it a little below fixed the issue.

I'll let you know once I have more info.
Thanks,
Mathieu

Data and Content Support » IQFeed Change To Simultaneous Requests (sudden "E,Too Many Connections" errors) Jan 16, 2021 09:37 AM (Total replies: 13)

My changes with 2.6.0 works well but you need to limit to 8 concurrent clients. For some reasons, passed this limit, even with the throttler in place, I'm getting ErrorMessage: Too many simultaneous history requests., MessageTrace: E,Too many simultaneous history requests.,

Hope this helps.

Hey Tim, thanks for your reply.

Since you dont really offer any support yet, is it possible to download archived version of mktsymbols_v2.zip for every week? This way I will be able to build my chains...
