"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
"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum
"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
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei
"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.

Using IQFeed with Interactive Brokers (IB) » Conversion between IQFeed <--> Interactive Brokers Ticker Symbols ? Mar 21, 2017 02:41 AM (Total replies: 2)

Good morning.
I am trading through IB but would like to use IQFeed as a data feed.
Is there a way to convert symbol names between IB and IQFeed?
I would like to automate this conversion because I have 500+ symbols...

Thanks

IQFeed Developer Support » Historical OHLC bars for quotes (bid/ask)? Mar 21, 2017 02:17 AM (Total replies: 5)

Thanks Tim for your reply. I will try to see what I can do with the data available through the API first and come back to you if I need additional data.

IQFeed Developer Support » Historical OHLC bars for quotes (bid/ask)? Mar 15, 2017 08:06 AM (Total replies: 5)

I am just getting started with IQFeed. In order to backtest some strategies, I need to retrieve 1-minute OHLC bars over extended periods of time (years)
So far, I only managed to get 1-minute OHLC bars for trades, but not quotes (bid and ask).
Is there a way to retrieve 1-minute OHLC bars for quotes?

Quotes are interesting too because they provide knowledge of the time-varying bid/ask spread and allow to simulate more accurately fills during backtesting.
I am familiar with Interactive Broker historical data. With Interactive Brokers, I can request OHLC bars for either the bid, the ask, the midpoint or for trades. Is there anything similar with IQFeed?

Thanks.
