"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

"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

It is our highest priority and we continue to make strides towards re-applying the historical data. Hopefully I will have enough information to provide an ETA in the next couple days for you, and the rest of the IQFeed community. Tim

We apologize for the interruption in the data, but please let us know if you see anything else going forward. Tim

Craig -DTN Guru- Posts: 326 Joined: Apr 16, 2010	Posted: Jul 14, 2014 05:41 PM Msg. 6 of 10 Would it be to much trouble to get the list? Can I infer from your post that this only affects 1 minute data?

jonnyb -DTN Evangelist- Posts: 122 Joined: Aug 15, 2012	Posted: Jul 15, 2014 06:05 PM Msg. 9 of 10 Tim, in the future, can you guys please make developers/users aware of such problems with blast emails? Unbeknownst to me, it looks like I've had automated systems running on bad data for weeks. Granted, I need to add some error checks to catch this behavior going forward, but if there's a known problem IQFeed should feel obligated to report it widely. Handling these things "quietly" is dead wrong.
