"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim

"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip

"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

"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

"I cannot believe what a difference it makes trading with ProphetX!" - Comment from Bruce in Los Angeles

"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe

"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger

Craig -DTN Guru- Posts: 326 Joined: Apr 16, 2010	Posted: Aug 3, 2010 02:13 PM Msg. 1 of 4 Today I had a series of disconnects from the Level 1 feed, I reconnected successfully but then noticed that the history connection has silently stopped working. Am I to assume that if I have to reconnect to the Level 1 port that I also have to reconnect to the history port? (Despite the fact no connection error is given on the history port). Update: I didn't notice before, but in my logs I see a E,Could not connect to History Socket. It would be amazingly helpful if the various errors one could receive on the history socket were documented, instead of having to find these things out via trial and error.

I'm not sure what would cause the history to stop working unless it is the same cause of your L1 disconnects. It certainly sounds like you had some network issues either on your end or somewhere between your ISP and our servers. After taking a look at the other thread, it sounds like there might be something else at work here. I'm going to continue this on that other thread http://forums.dtn.com/index.cfm?page=topic&topicID=2871 (for anyone else following along).
