"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

Author	Topic: 2.3.0.3 Timing issue for watch list (5 messages, Page 1 of 1)
ensign -Interested User- Posts: 2 Joined: Jun 6, 2005	Posted: Jun 6, 2005 04:16 PM Msg. 1 of 5 Testing with 2.3.0.3 and using the watch command in a loop to ask for 40+ symbols to be watched. Upon initial request for 40 symbols, the Connection Manager Feed Stats form will show 6 symbols. If I repeat the request the number of symbols followed will go to 11, repeat full list again, number of symbols followed will go to 16, then to 21, etc. This I can verify by seeing which Fundamental records are returned. My conclusion is that I am making requests to the watch list faster than the IQfeed Connect can process the requests, or is there a handshake I should be using so I do not overrun the request process. I interface directly with the DLL using Delphi 6. The TCP/IP socket is using this type of an example string: tcp5009.sendln('wIBM'+#13+#10+#0+#1,#1) I have a 1/50th of a second delay after the string is sent to the socket, as that seemed to be an effective delay pace for the 2.3.0.1 version. How should I be sending the watch list so all symbols are reliably processed and begin to update? Thanks. Sincerely, Howard Arrington www.ensignsoftware.com

I wasn't aware of this issue, but will look into it. It there a watchlist file that you can send to the developer support email, so I can test with ensign and IQFeed? Thanks!

Posted: Jun 7, 2005 11:28 AM Msg. 3 of 5 Quote: tcp5009.sendln('wIBM'+#13+#10+#0+#1,#1) I am curious why you send the extra 'stuff' at the end of the watch request. The DTN API shows: w[symbol]\n. I just send the symbol followed by the #10 linefeed character (as per API and empirical testing). Has been working well for all client versions. Maybe I am missing something...

ensign -Interested User- Posts: 2 Joined: Jun 6, 2005	Posted: Jun 8, 2005 02:02 PM Msg. 4 of 5 This issue has been resolved via a change in Ensign to watch all symbols using one request instead of making multiple requests with 1 symbol per request. Thanks for the feedback. Sincerely, Howard Arrington www.ensignsoftware.com

But, you can also watch one symbol at a time. If anyone is having issues with that, let me know. I need to make sure that either way is reliable. Thanks! Natalie Natalie Hannan DTN Market Access, LLC.
