"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
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"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
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email
"Everything is working great with the API. I love it." - Comment from Calvin
"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
"IQ feed is brilliant. The support is mind-bending. What service!" - Comment from Public Forum Post
"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
"You have an excellent product !!!!!!" - Comment from Arely

IQFeed Developer Support » Java API for IQFeed - IQFeed4j Jun 11, 2021 06:08 PM (Total replies: 0)

Hey everyone,

I've been using IQFeed for several months now and it has been great. Thank you to all IQFeed staff for building an excellent platform for high quality market data and giving developers easy access to it!

I've been developing in Java for over 6 years now and when I started to use IQFeed, I noticed there wasn't a full Java API on Github or anywhere else. So, I made one! It's called IQFeed4j available here: https://github.com/Petersoj/IQFeed4j
I wrote it with ease-of-use and performance in mind. Try it out if you've programmed in Java! It works wonders when used with Interactive Brokers' IBKR Java API.

Give it a Star on Github!

Thanks,

Jacob Peterson
