"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

"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email

IQFeed Developer Support » Derivative data ports problem Mar 6, 2021 09:36 AM (Total replies: 0)

Hi,

I think that the derivative data connection is not respecting the ports settings in Registry when it is spawning underlying connections to the history port and the Level1 data port. Can someone confirm this?

Moreover, I would like to know how does the derivative data connection filter out bad ticks? Can someone disclose the maths here?

Thanks.

Data and Content Support » No (backfilling?) data on Amibroker and IQFeed Charts Feb 21, 2021 06:04 PM (Total replies: 3)

Hello again :),

Just talked to tech support and everything is working now. I really love the quality of the customer service.

For anyone who is hitting the same problem. It turns out that, IQFeed is using same port with logitech GHub. Close it and it is working.

Data and Content Support » No (backfilling?) data on Amibroker and IQFeed Charts Feb 20, 2021 07:16 PM (Total replies: 3)

Hello,

I have just subscribed to the service and all charts are not displaying any data. I understand that the US Stock market is close at the moment when I am performing the test but should I be getting any backfilling data? I have attached a screenshot. Any suggestions?

Thanks.
