"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton

"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

"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email

"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email

"IQ feed is brilliant. The support is mind-bending. What service!" - Comment from Public Forum Post

"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum

"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

"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

"Version 4.0.0.2 has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

Author	Topic: Delayed Data On CLM (11 messages, Page 1 of 1)
Craig -DTN Guru- Posts: 326 Joined: Apr 16, 2010	Posted: Oct 10, 2018 04:54 PM Msg. 1 of 11 Today I had some trouble closing out positions. Up on examining what went wrong, it appears CLM data was delayed. I have attached the downloaded tick data from today and what I recorded live...quite a lag.

Craig -DTN Guru- Posts: 326 Joined: Apr 16, 2010	Posted: Oct 10, 2018 04:56 PM Msg. 2 of 11 ...and here is the recorded data, notice how the peak at 12 is already behind. I checked other higher volume contracts I was trading and they were all fine. This is making me nervous... File Attached: recorded.png (downloaded 1207 times)

We don't have any way for only some of the symbols to become delayed. All outgoing data is placed on the same stack for broadcast to your client and is sent in a single thread. Did you happen to check the clientstats for this at the time or do you have your IQFeed log from when it happened? Tim

Craig -DTN Guru- Posts: 326 Joined: Apr 16, 2010	Posted: Oct 11, 2018 02:04 PM Msg. 7 of 11 Yahoo seems to indicate a last trade time of approx 3, the snap quote still shows 14:49 for bid/ask time.

DTN_Tim Walter -DTN Guru- Posts: 1238 Joined: Apr 25, 2006	Posted: Oct 11, 2018 02:39 PM Msg. 9 of 11 Craig, That is listed as a NYSE_AMERICAN (formerly NYSE_AMEX) symbol and I don't see that as something that you are subscribed to currently for real time data. It looks like you just have the real time data on Nasdaq and NYSE only. I don't see any recent changes on your account, but if something sounds amiss with that just let me know and we can try to figure it out. Is this a new symbol that you recently started watching? Tim

I'll check my subscriptions. Edit: My bad. I'm just glad it was something obvious :) Edited by Craig on Oct 11, 2018 at 02:46 PM
