"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email

"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"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

"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

"I used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post

"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

"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.

"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

"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike

"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen

This was caused by issues with the exchange feed. https://www.wsj.com/articles/some-stock-prices-delayed-as-glitch-hits-nyse-run-data-feed-11565654989 - Has/will it been rectified? The data cannot be corrected, there is no source of data to correct from as it was bad from the exchange. But yes the exchange has fixed its issues. - Does it affect other symbols? Yes, this could have occurred for any NYSE/NYSE American/ARCA/BATS stocks. Most likely you are seeing regional market quotes updating in the streaming feed. These quotes are not stored in the tick history, only the best bid/ask at the time of the trade are stored and the bed bid was stuck during this time due to the issues at the exchange.
